Fig. 1 is the flow diagram for the display control method that one embodiment of the application provides, and this method is applied to three-dimensional The control of virtual camera in virtual world, the virtual camera exist according to the screen accounting of the display screen in user terminal Two-dimensional display area is mapped out in the display screen, the virtual camera shoots it in the three-dimensional virtual world Virtual scene is mapped in two-dimensional display area, and the virtual scene includes target roles.User terminal for example can for mobile phone, Tablet computer, laptop etc., the present exemplary embodiment does not do particular determination to this.Fig. 2 provides for one embodiment of the application Virtual camera view centrum schematic diagram.Virtual camera 201 is virtual camera 201 three-dimensional empty depending on centrum 202 The visual field in the quasi- world, i.e. visual range include hither plane 203 and far plane 304 depending on centrum 202, depending on close flat in centrum 202 Face 203 and far plane 204 define the visual range of virtual camera 201.Specifically, if role distance virtual camera 201 Distance be greater than far plane 204 or be less than hither plane 203, then role will not be taken by virtual camera 201, thus also not It can show on the display screen, in other words, can virtually be taken the photograph depending on role of the centrum 202 between hither plane 203 and far plane 204 Camera 201 takes, and then shows on the display screen.Based on this, two-dimensional display area is virtual camera 201 according to user Visual range between its hither plane 203 and far plane 204 is mapped to display screen by the screen accounting of the display screen in terminal In region, due to regarding 202 own form of centrum, two-dimensional display area is rectangular area.As shown in Figure 1, this method It may include step S110~S140, in which:

Step S110, the first predeterminable area and the second predeterminable area are set in the two-dimensional display area, wherein described Second predeterminable area is in first predeterminable area；

Step S120, based on first predeterminable area and second predeterminable area setting first direction and second party To；

Step S130, the most big end and smallest end and described second of the target roles in said first direction are determined Most big end and smallest end on direction；

Step S140, judge whether the target roles are overlapped and on the first direction with second predeterminable area Most big end and smallest end in most big end and smallest end and second direction are preset in first predeterminable area and described second Between region, if it is not, then adjusting shooting angle and/or the camera site of the virtual camera.

In the embodiment of the present application, on the one hand, judge whether target roles are overlapped with the second predeterminable area and target roles exist Most big end in smallest end and most big end and second direction and smallest end on first direction is pre- in the first predeterminable area and second If between region, if it is not, then adjust shooting angle and/or the camera site of virtual camera, in other words, in target roles and the Under the premise of two predeterminable areas are overlapped, as long as ensuring target roles smallest end in a first direction and most big end and second direction On smallest end and most big end be between the first predeterminable area and the second predeterminable area, then do not adjust the shooting of virtual camera Angle and/or camera site, i.e., ensuring that target roles under the premise of will not remove two-dimensional display area, mention for target roles Biggish space has been supplied, so that the control to target roles is more flexible, expansibility is strong, and the user experience is improved, and Virtual camera need not be moved according to the movement of target roles in real time；On the other hand, in advance due to the first predeterminable area and second If region can be set in any region of two-dimensional display area, therefore, the control to target roles is further increased Flexibility.

The display control method provided in the embodiment of the present application is described further next, with reference to Fig. 1.

In step s 110, the first predeterminable area and the second predeterminable area are set in the two-dimensional display area, wherein Second predeterminable area is in first predeterminable area.

In the embodiment of the present application, the shape of first predeterminable area and the second predeterminable area for example can for rectangle, Circle, triangle etc., the present exemplary embodiment does not do particular determination to this.The shape of first predeterminable area and the second predeterminable area It may be the same or different, do not do particular determination in the present exemplary embodiment to this.First predeterminable area and the second preset areas Domain can be set in any one of two-dimensional display area position, for example, the middle position of two-dimensional display area is set, then For example, the position etc. in the upper left corner of two-dimensional display area is arranged in, the present exemplary embodiment does not do particular determination to this.

Since two-dimensional display area is that virtual camera is close flat by it according to the screen accounting of the display screen in user terminal Visual range between face and far plane is mapped to the region in display screen, therefore can pass through the view vertebra in virtual camera The first preset areas is arranged in the mode that two nested regions are arranged between the hither plane and far plane of body in two-dimensional display area The region of domain and the second predeterminable area, two of them nesting can be the first detection zone and the second detection zone, and second examines Region is surveyed in the first detection zone, the first detection zone is mapped to the region in two-dimensional display area is determined as first and preset Second detection zone is mapped to the region in two-dimensional display area and is determined as the second predeterminable area by region.It should be noted that The first predeterminable area and the second predeterminable area can be set by the shape of the first detection zone of setting and the second detection zone Shape, can by setting the first detection zone and the second detection zone view centrum in hither plane and far plane between Position is arranged the position of the first predeterminable area and the second predeterminable area in two-dimensional display area.

For example, Fig. 3 is that the first predeterminable area in two-dimensional display area that one embodiment of the application provides and second are pre- If the schematic diagram in region, as can be known from Fig. 3, two-dimensional display area 301, the first predeterminable area 302 and the second predeterminable area 303 It is rectangle, and the second predeterminable area 303 is arranged in the first predeterminable area 302.

In the step s 120, first direction and second is arranged based on first predeterminable area and second predeterminable area Direction.

In the embodiment of the present application, it can be set by point on the basis of the center of the first predeterminable area and the second predeterminable area First direction and second direction are set, can also be set using the point of other in the first predeterminable area and the second predeterminable area as datum mark First direction and second direction are set, the present exemplary embodiment does not do particular determination to this.It should be noted that first direction and Two directions can be vertical, and first direction and second direction can not also do particular determination to this with out of plumb, the present exemplary embodiment.

In step s 130, the target roles most big end in said first direction and smallest end and described are determined Most big end and smallest end in second direction.

In the embodiment of the present application, the determination process of target roles most big end in a first direction and smallest end can wrap Include: maximum in the positive direction for determining first direction in all boundary points subpoint in a first direction of target roles is thrown Minimum projection's point in the negative direction of shadow point and first direction, and the maximal projection point in the positive direction of first direction is determined as Minimum projection's point in the negative direction of first direction is determined as target roles and existed by the most big end of target roles in a first direction Smallest end on first direction.Similarly, the determination process of target roles most big end in a second direction and smallest end can wrap It includes: the most projection in positive direction for determining second direction in all boundary points subpoint in a second direction of target roles Minimum projection's point in a little bigger and negative direction of second direction, and the maximal projection point in the positive direction of second direction is determined as Minimum projection's point in the negative direction of second direction is determined as target roles and existed by the most big end of target roles in a second direction Smallest end in second direction.

For example, Fig. 4 provides the most big end and minimum of role in a first direction that set the goal really for one embodiment of the application The schematic diagram of end and the most big end in second direction and smallest end.As shown in Figure 4, target roles 304 are a five-pointed star, two dimension Display area 301, the first predeterminable area 302 and the second predeterminable area 303 are rectangle, first direction 305 and second direction 306 Vertically.Wherein, the positive direction in the direction 305 that the direction that arrow is directed toward in first direction 305 is first, arrow in first direction 305 The opposite direction that head is directed toward is the negative direction of first direction 305, and the direction that arrow is directed toward in second direction 306 is second direction 306 Positive direction, the opposite direction that arrow is directed toward in second direction 306 is the negative direction of second direction 306.As shown in Figure 4, subpoint 307 be the most big end in target roles 304 in a first direction 305, and subpoint 308 is in target roles 304 in a first direction 305 Smallest end, subpoint 309 be most big end of the target roles 304 in second direction 306, subpoint 310 be target roles 304 Smallest end in second direction 306.

In step S140, judge whether the target roles are overlapped and the first direction with second predeterminable area On most big end and the most big end in smallest end and second direction and smallest end in first predeterminable area and described second Between predeterminable area, if it is not, then adjust shooting angle and/or the camera site of the virtual camera so that target roles with Second predeterminable area is overlapped and the most big end on first direction and the most big end in smallest end and second direction and smallest end exist Between first predeterminable area and the second predeterminable area.

In the embodiment of the present application, Fig. 5 is the shooting angle for the adjustment virtual camera that one embodiment of the application provides Degree and/or the flow diagram of camera site.As shown in figure 5, may comprise steps of:

Step S510, judge whether the target roles are overlapped and on the first direction with second predeterminable area Most big end and smallest end in most big end and smallest end and second direction is in first predeterminable area.

In the embodiment of the present application, target roles can refer to that target roles are default with second with being overlapped for the second predeterminable area Region is at least partly overlapped, and is based on this, if there is the part being overlapped in target roles and the second predeterminable area, target roles and the Two predeterminable areas are overlapped, if target roles are not overlapped completely with the second predeterminable area, target roles and the second predeterminable area are not It is overlapped.

Judge that the process whether target roles are overlapped with the second predeterminable area may include: to establish based on two-dimensional display area Rectangular coordinate system；The coordinate of each point of target roles is obtained in rectangular coordinate system；It is pre- that second is obtained in rectangular coordinate system If the coordinate of each point in region；By the coordinate of each point in target roles respectively with each point in the second predeterminable area Coordinate be compared, and judge target roles and the second predeterminable area with the presence or absence of the identical point of coordinate according to comparison result； If it exists, then target roles are overlapped with the second predeterminable area, and if it does not exist, then target roles are not overlapped with the second predeterminable area.

Judge the most big end of target roles in a first direction and most big end and minimum in smallest end and second direction Whether end may include: the seat that the most big end on first direction is obtained in rectangular coordinate system in the process in the first predeterminable area Mark, the coordinate of smallest end on first direction, the coordinate of most big end in second direction, smallest end in second direction seat Mark；The coordinate range of the first predeterminable area is obtained in rectangular coordinate system；Judge the most big end on first direction coordinate whether In the coordinate range of the first predeterminable area, if so, the most big end on first direction is in the first predeterminable area, if it is not, then Most big end on first direction is outside the first predeterminable area；Due to judging the smallest end on first direction, in second direction most Smallest end in big end and second direction whether in the first predeterminable area principle and above-mentioned judgement first direction on most Whether principle in the first predeterminable area is identical for big end, therefore is not repeating herein.

For example, as shown in figure 4, in conjunction with above-mentioned deterministic process it is found that target roles 304 are overlapped with the second predeterminable area 303, And the most big end in the most big end 307 and smallest end 308 and second direction 306 on 305 in a first direction of target roles 304 309 and smallest end 310 in the first predeterminable area 302.

It should be noted that the process for obtaining the coordinate of each point of target roles can be with are as follows: in virtual camera Depending in centrum construct three-dimensional perpendicular coordinate system, wherein Z axis with view centrum hither plane and far plane it is vertical, X-axis and Y-axis composition Plane is parallel with hither plane and far plane；Obtain coordinate of each point in target roles in three-dimensional perpendicular coordinate system；To mesh It marks coordinate of each point in role in three-dimensional perpendicular coordinate system and carries out projective transformation and matrix algorithm, to calculate target roles In each point from the coordinate that should be arranged in two-dimensional display area in virtual three-dimensional scene.It should be noted that can also basis The coordinate of each point needed for above-mentioned principle acquisition above.

Step S520, if it is not, then adjusting shooting angle and/or the camera site of the virtual camera, so that the mesh Mark role is overlapped and in most big end and smallest end and second direction on the first direction with second predeterminable area Most big end and smallest end are in first predeterminable area.

In the embodiment of the present application, by according to following different situation to adjustment virtual camera shooting angle and/or The process of camera site is described in detail.

The first, if the target roles be overlapped with second predeterminable area and the most big end on the first direction and One in most big end and smallest end in smallest end and second direction then controls the void outside first predeterminable area Quasi- direction rotary taking angle of the video camera to the end outside first predeterminable area, so that target roles and the second preset areas Domain is overlapped and the most big end on first direction and the most big end in smallest end and second direction and smallest end are default first In region.

In the embodiment of the present application, for example, Fig. 6 is the target roles and the second predeterminable area that one embodiment of the application provides It is overlapped, and schematic diagram of the smallest end of target roles in a first direction outside the first predeterminable area.As can be known from Fig. 6, due to Target roles 304 be overlapped with the second predeterminable area 303 and only target roles 304 in a first direction the smallest end 308 on 305 Outside one predeterminable area 302, therefore control the direction rotary taking angle of smallest end 308 of the virtual camera on first direction 305 Degree, so that the smallest end 308 on first direction 305 enters the first predeterminable area 302, to make target roles 304 and second in advance If region 303 is overlapped, and the most big end 307 and smallest end 308 on first direction 305 and the most big end in second direction 306 309 and smallest end equal 310 in the first predeterminable area 302.

Similarly, if target roles be overlapped with the second predeterminable area and only the most big end of target roles in a first direction Outside one predeterminable area, then the direction rotary taking angle of most big end of the virtual camera on first direction is controlled.If target angle Color is overlapped with the second predeterminable area and only the most big end of target roles in a second direction then controls void outside the first predeterminable area The direction rotary taking angle of quasi- most big end of the video camera in second direction.If target roles be overlapped with the second predeterminable area and Only the smallest end of target roles in a second direction then controls virtual camera in second direction outside the first predeterminable area The direction rotary taking angle of smallest end.

It should be noted that the first predeterminable area and second is preset due in the shooting angle rotation of virtual camera Region also with rotation, therefore can according to the current location of the first predeterminable area and make end outside the first predeterminable area just into Enter the rotation angle of the shooting angle of the position calculating virtual camera of the critical edge of the first predeterminable area；It can also be according to first The current location of predeterminable area and the position for making the end outside the first predeterminable area be moved to designated position in the first predeterminable area are counted The rotation angle of shooting angle etc. of virtual camera is calculated, the present exemplary embodiment does not do particular determination to this.

Second, if the target roles be overlapped with second predeterminable area and the most big end on the first direction and One in smallest end and one in the most big end and smallest end in the second direction are outside first predeterminable area, then The virtual camera is controlled successively to the direction rotary taking angle at two ends outside first predeterminable area, so that mesh Mark role is overlapped with second predeterminable area and the most big end in most big end and smallest end and second direction on first direction With smallest end in the first predeterminable area.

In the embodiment of the present application, Fig. 7 is that the target roles that one embodiment of the application provides are overlapped with the second predeterminable area, And schematic diagram of the most big end outside the first predeterminable area in the smallest end and second direction of target roles in a first direction.From figure In 7 it is found that since target roles 304 are overlapped with the second predeterminable area 303, and target roles 304 in a first direction on 305 most Most big end 309 on small end 308 and second direction 306 is outside the first predeterminable area 302, therefore, control virtual camera first to 308 rotary taking angle of smallest end on the first direction 305 309 rotary taking angle of most big end in second direction 306 again, Or control virtual camera first 309 rotary taking angle of most big end in second direction 306 again on first direction 305 308 rotary taking angle of smallest end, so that most big end 309 enters the in smallest end and second direction 306 on first direction 305 One predeterminable area 302, to make target roles 304 be overlapped with the second predeterminable area 303, and the most big end on first direction 305 307 and the most big end 309 in smallest end 308 and second direction 306 and smallest end equal 310 in the first predeterminable area 302.

Similarly, if target roles be overlapped with the second predeterminable area and in most big end and second direction on first direction most Big end outside the first predeterminable area, then control virtual camera first most big end rotary taking angle on first direction again to the Most big end rotary taking angle on two directions, or the first most big end rotary taking in second direction of control virtual camera The angle most big end rotary taking angle on first direction again.

If target roles are overlapped with the second predeterminable area and the smallest end in most big end and second direction on first direction Outside the first predeterminable area, then most big end rotary taking angle of the virtual camera first on first direction is controlled again to second party Upward smallest end rotary taking angle, or the first smallest end rotary taking angle in second direction of control virtual camera Most big end rotary taking angle on first direction again.

If target roles are overlapped with the second predeterminable area and the smallest end in smallest end and second direction on first direction Outside the first predeterminable area, then smallest end rotary taking angle of the virtual camera first on first direction is controlled again to second party Upward smallest end rotary taking angle, or the first smallest end rotary taking angle in second direction of control virtual camera Smallest end rotary taking angle on first direction again.

It should be noted that the determination principle of the rotation angle of the shooting angle of virtual camera and the first situation above In principle it is identical, therefore do not repeating herein.

The third, if the target roles be overlapped with second predeterminable area and the most big end on the first direction and Smallest end then controls the virtual camera and claps to the direction adjustment far from the target roles outside first predeterminable area It acts as regent and sets, so that target roles are overlapped with second predeterminable area and the most big end on first direction and smallest end and second party Upward most big end and smallest end are in the first predeterminable area.

In the embodiment of the present application, Fig. 8 is that the target roles that one embodiment of the application provides are overlapped with the second predeterminable area, And the schematic diagram of smallest end and most big end outside the first predeterminable area of target roles in a first direction.As can be known from Fig. 8, by It is overlapped in target roles 304 with the second predeterminable area 303, and 305 most big end 307 and smallest end 308 exist on first direction Outside first predeterminable area 302, therefore, control virtual camera adjusts camera site to the direction far from target roles 304, to subtract Few target roles 304 area shared in two-dimensional display area 301 so that on first direction 305 most big end 307 and minimum End 308 enters the first predeterminable area 302, and then is overlapped target roles 304 and on first direction with the second predeterminable area 303 Most big end 309 and smallest end 310 in 305 most big end 307 and smallest end 308 and second direction 306 is default first In region 302.

It should be noted that can be according to the current area (area i.e. under current state) of target roles and first Area (the face under dbjective state of target roles when most big end and smallest end on direction are just into the first predeterminable area Product) distance of the virtual camera far from target roles is calculated, it can also be according to the current area of target roles (i.e. under current state Area) and target angle when entering corresponding position in the first predeterminable area of most big end in a first direction and smallest end The area (area i.e. under dbjective state) of color calculates distance etc. of the virtual camera far from target roles, the present exemplary embodiment Particular determination is not done to this.

4th kind, if the target roles be overlapped with second predeterminable area and the most big end in the second direction and Smallest end then controls the virtual camera and claps to the direction adjustment far from the target roles outside first predeterminable area It acts as regent and sets, so that target roles are overlapped with second predeterminable area and the most big end on first direction and smallest end and second party Upward most big end and smallest end are in the first predeterminable area.

In the embodiment of the present application, Fig. 9 is that the target roles that one embodiment of the application provides are overlapped with the second predeterminable area, And the schematic diagram of smallest end and most big end outside the first predeterminable area of target roles in a second direction.As can be known from Fig. 9, mesh Mark role 304 is overlapped with the second predeterminable area 303, and most big end 309 in second direction 306 and smallest end 310 are first Outside predeterminable area 302, therefore, control virtual camera adjusts camera site to the direction far from target roles 304, to reduce mesh The area shared in two-dimensional display area 301 of role 304 is marked, so that most big end 309 and smallest end in second direction 306 310 move into the first predeterminable area 302, and then are overlapped target roles 304 with the second predeterminable area 303 and 305 on first direction Most big end 307 and most big end 309 in smallest end 308 and second direction 306 and smallest end 310 in the first predeterminable area In 302.

It should be noted that determination of distance principle of the virtual camera far from target roles and above the third situation In determination principle it is identical, therefore do not repeating herein.

5th kind, if the target roles be overlapped with second predeterminable area and the most big end on the first direction and At least three in most big end and smallest end in smallest end and second direction then control institute outside first predeterminable area It states virtual camera and adjusts camera site to the direction far from the target roles, so that target roles and second preset areas Domain is overlapped and the most big end in most big end and smallest end and second direction on first direction and smallest end are in the first preset areas In domain.

In the embodiment of the present application, for example, Figure 10 is the target roles and the second preset areas that one embodiment of the application provides Domain is overlapped, and smallest end in the smallest end and second direction of target roles in a first direction and most big end are in the first preset areas Overseas schematic diagram.As shown in Figure 10, it is overlapped due to target roles 304 with the second predeterminable area 303, and on first direction 305 Smallest end 308 and second direction 306 on most big end 309 and smallest end 310 outside the first predeterminable area 302, therefore, control Virtual camera processed adjusts camera site to the direction far from target roles 304, to reduce target roles 304 in two-dimentional viewing area Shared area in domain 301, so that most big end 309 in smallest end 308 and second direction 306 on first direction 305 and most Small end 310 is moved into the first predeterminable area 302, and then is overlapped target roles 304 with the second predeterminable area 303 and first direction Most big end 309 and smallest end 310 in upper 305 most big end 307 and smallest end 308 and second direction 306 is pre- first If in region 302.

It should be noted that determination of distance principle of the virtual camera far from target roles and situation in above third In determination principle it is identical, therefore do not repeating herein.

6th kind, if the target roles are not overlapped with second predeterminable area, adjust the virtual camera The shooting angle and camera site of shooting angle or the adjustment virtual camera, so that the target roles and described second Predeterminable area is overlapped and the most big end on the first direction and the most big end in smallest end and second direction and smallest end exist In first predeterminable area.

In the embodiment of the present application, when target roles are not overlapped with the second predeterminable area, according to target roles and second The positional relationship of predeterminable area rotates the shooting angle of virtual camera, is overlapped target roles with the second predeterminable area, example Such as, target roles then rotate the shooting angle of virtual camera in the top position of the second predeterminable area upwards；For another example mesh Role is marked in the left location of the second predeterminable area, then rotates to the left the shooting angle of virtual camera.In target roles and the After two predeterminable areas are overlapped, can according to it is above-mentioned the first to the 5th kind of situation adjustment virtual camera shooting angle or shooting Position is overlapped target roles with the second predeterminable area and in most big end and smallest end and second direction on first direction Most big end and smallest end are in the first predeterminable area.It should be noted that be not overlapped with the second predeterminable area in target roles and When not in two-dimensional display area, the camera site of virtual camera can be adjusted first, target roles is made to enter two-dimentional display Region is overlapped target roles with the second predeterminable area further according to above-mentioned adjustment process, finally, according to it is above-mentioned the first to the 5th The shooting angle of kind of situation adjustment virtual camera or camera site are overlapped target roles with the second predeterminable area and first party Most big end and smallest end in upward most big end and smallest end and second direction is in the first predeterminable area.

Step S530, judge the target roles most big end in said first direction and smallest end and second direction On most big end and smallest end whether outside second predeterminable area.

In the present example embodiment, step S530 is to be overlapped in target roles with the second predeterminable area, and target roles Most big end and smallest end on most big end and smallest end and second in a first direction is reversed is in the first predeterminable area On the basis of, judge the most big end of target roles in a first direction and most big end and smallest end in smallest end and second direction Whether outside the second predeterminable area.It should be noted that due to having determined target roles and the second predeterminable area in step 520 It is overlapped, therefore in this step no longer judges whether target roles are overlapped with the second predeterminable area.

Due to judge the most big end in the most big end and smallest end and second direction of target roles in a first direction and Smallest end whether outside the second predeterminable area principle and step S510 in judge the most big end of target roles in a first direction Whether principle in the first predeterminable area is identical with most big end and the smallest end in smallest end and second direction, therefore herein It is not repeating.

Step S540, if it is not, then adjusting shooting angle or the camera site of the virtual camera, so that the target angle Color is overlapped with second predeterminable area and the maximum in most big end and smallest end and second direction on the first direction End and smallest end are between first predeterminable area and second predeterminable area.

In the embodiment of the present application, by the shooting angle or shooting according to following different situation to adjustment virtual camera The process of position is described in detail.

The first, if in the most big end and smallest end and second direction of the target roles in said first direction One in most big end and smallest end then controls the virtual camera to pre- described second in second predeterminable area If the opposite direction rotary taking angle at the end in region, so that target roles are overlapped with the second predeterminable area and on first direction Most big end in most big end and smallest end and second direction and smallest end are between the first predeterminable area and the second predeterminable area.

In the embodiment of the present application, for example, Figure 11 is the target roles and the second preset areas that one embodiment of the application provides Domain is overlapped, and schematic diagram of the smallest end of target roles in a first direction in the second predeterminable area.As can be known from Fig. 11, mesh Smallest end 308 of the role 304 in a first direction on 305 is marked in the second predeterminable area 303, then controls virtual camera to first The opposite direction rotary taking angle of smallest end 308 on direction 305, i.e., control virtual camera on first direction 305 most The direction rotary taking angle of big end 307, so that the smallest end 308 on first direction 305 is removed in the second predeterminable area 303, And then it is overlapped target roles 304 with second predeterminable area 303 and most big end 307 and smallest end on first direction 305 308 and the most big end 309 in second direction 306 and smallest end 310 in the first predeterminable area 302 and the second predeterminable area 303 Between.

Similarly, if the most big end of target roles in a first direction controls virtual camera in the second predeterminable area The opposite direction rotary taking angle of most big end on first direction；If the most big end of target roles in a second direction is second In predeterminable area, then the opposite direction rotary taking angle of most big end of the virtual camera in second direction is controlled；If target angle The smallest end of color in a second direction then controls smallest end of the virtual camera in second direction in the second predeterminable area Opposite direction rotary taking angle.

It should be noted that the first predeterminable area and second is preset due in the shooting angle rotation of virtual camera Region according to the current location of the second predeterminable area and can be such that the end in the second predeterminable area moves just also with rotation The position of the critical edge of the second predeterminable area calculates the rotation angle of the shooting angle of virtual camera out；It can also be according to second The current location of predeterminable area and the position for making the end in the second predeterminable area be moved to the outer designated position of the second predeterminable area are counted The rotation angle of shooting angle etc. of virtual camera is calculated, the present exemplary embodiment does not do particular determination to this.

Second, if one in the most big end and smallest end of the target roles in said first direction and described the One in most big end and smallest end on two directions then controls the virtual camera successively in second predeterminable area To the opposite direction rotary taking angle at two ends in second predeterminable area, so that target roles and the second predeterminable area It is overlapped and the most big end on first direction and the most big end in smallest end and second direction and smallest end is in the first predeterminable area And second between predeterminable area.

In the embodiment of the present application, for example, Figure 12 is the target roles and the second preset areas that one embodiment of the application provides Domain is overlapped, and most big end the showing in the second predeterminable area in the smallest end and second direction of target roles in a first direction It is intended to.As can be known from Fig. 12, target roles 304 in a first direction the smallest end 308 on 305 and in second direction 306 most Big end 309 is in the second predeterminable area 303, therefore, can control smallest end of the virtual camera first on first direction 305 The opposite direction rotary taking angle of the 308 opposite direction rotary taking angle most big end 309 in second direction 306 again, or The opposite direction rotary taking angle of most big end 309 of the virtual camera first in second direction 306 is controlled again to first direction 305 On smallest end 308 opposite direction rotary taking angle so that in smallest end 308 and second direction 306 on first direction 305 Most big end 309 remove the second predeterminable area 303, and then be overlapped target roles 304 with the second predeterminable area 303 and first party It is pre- first to the most big end 307 and smallest end 308 on 305 and the most big end 309 in second direction 306 and smallest end 310 If between region 302 and the second predeterminable area 303.

Similarly, if the most big end in the most big end and second direction of target roles in a first direction is in the second predeterminable area It is interior, then the opposite direction rotary taking angle of the first most big end on first direction of virtual camera is controlled again in second direction The opposite direction rotary taking angle of most big end, or the opposite direction rotation of the first most big end in second direction of control virtual camera Turn the opposite direction rotary taking angle of most big end of the shooting angle again on first direction；If target roles are in a first direction One in smallest end in most big end and second direction then controls virtual camera first to first party in the second predeterminable area The opposite direction rotary taking angle of the opposite direction rotary taking angle of the upward most big end smallest end in second direction again, or Person control virtual camera first smallest end in second direction opposite direction rotary taking angle again on first direction most The opposite direction rotary taking angle of big end；If the smallest end in the smallest end and second direction of target roles in a first direction exists In second predeterminable area, then control virtual camera first smallest end on first direction anti-reverse rotation shooting angle again to The opposite direction rotary taking angle of smallest end in second direction, or the first minimum in second direction of control virtual camera The opposite direction rotary taking angle of the opposite direction rotary taking angle at the end smallest end on first direction again.

It should be noted that the determination principle of the rotation angle of the shooting angle of virtual camera and above the first feelings Determination principle in condition is identical, therefore is not repeating herein.

The third, if the target roles most big end in said first direction and smallest end are in second preset areas In domain, then control the virtual camera to close to the target roles direction adjust camera site so that target roles with Second predeterminable area is overlapped and the most big end on first direction and the most big end in smallest end and second direction and smallest end exist Between first predeterminable area and the second predeterminable area.

In the present example embodiment, Figure 13 is the target roles and the second predeterminable area weight that one embodiment of the application provides It closes, and the schematic diagram of smallest end and most big end in the second predeterminable area of target roles in a first direction.Due to 13 it is found that The smallest end 308 on 305 and most big end 307 are in the second predeterminable area 303 in a first direction for target roles 304, therefore, control Virtual camera adjusts shooting angle to the direction close to target roles 304, to increase target roles 304 in two-dimensional display area In shared area, and then make the smallest end 308 and most big end 307 the second predeterminable area 303 of removal on first direction 305, from And make target roles 304 be overlapped with the second predeterminable area 303 and the most big end 307 on first direction 305 and smallest end 308 and Most big end 309 in second direction 306 and smallest end 310 are between the first predeterminable area 302 and the second predeterminable area 303.

It should be noted that can be according to the current area (area i.e. under current state) of target roles and first Area (the face i.e. under dbjective state of target roles when most big end and smallest end on direction are just moved out the second predeterminable area Product) calculate virtual camera close to the distance of target roles, can also be according to the current area of target roles (i.e. under current state Area) and target when being moved to corresponding position outside the second predeterminable area of most big end in a first direction and smallest end The area (area i.e. under dbjective state) of role calculates virtual camera close to the distance etc. of target roles, this exemplary implementation Example does not do particular determination to this.

It can be according to the most big end and minimum on the position of most big end and smallest end on first direction and first direction End is just moved out the distance that the position of the second predeterminable area determines virtual camera close to target roles, can also be according to first party The upward position of most big end and smallest end and the most big end on first direction and smallest end are moved to outside the second predeterminable area Corresponding designated position determines that distance etc. of the virtual camera close to target roles, the present exemplary embodiment do not do special limit to this It is fixed.

4th kind, if the target roles most big end in this second direction and smallest end are in second preset areas In domain, then control the virtual camera to close to the target roles direction adjust camera site so that target roles with Second predeterminable area is overlapped and the most big end on first direction and the most big end in smallest end and second direction and smallest end exist Between first predeterminable area and the second predeterminable area.

In the present example embodiment, Figure 14 is the target roles and the second predeterminable area weight that one embodiment of the application provides It closes, and the schematic diagram of smallest end and most big end in the second predeterminable area of target roles in a second direction.Due to 14 it is found that Target roles 304 in the second predeterminable area 303, therefore, are controlled in the smallest end 310 in second direction 306 and most big end 309 Virtual camera adjusts shooting angle to the direction close to target roles 304, to increase target roles 304 in two-dimensional display area In shared area, and then make the smallest end 310 and most big end 309 the second predeterminable area 303 of removal in second direction 306, from And make target roles 304 be overlapped with the second predeterminable area 303 and the most big end 307 on first direction 305 and smallest end 308 and Most big end 309 in second direction 306 and smallest end 310 are between the first predeterminable area 302 and the second predeterminable area 303.

It should be noted that virtual camera is in the determination of distance principle and the third situation above of target roles Determination principle it is identical, therefore do not repeating herein.

5th kind, if in the most big end and smallest end and second direction of the target roles in said first direction In most big end and smallest end at least three in second predeterminable area, then control the virtual camera to close to described The direction of target roles adjusts camera site, so that target roles are overlapped with the second predeterminable area and the most big end on first direction And most big end in smallest end and second direction and smallest end are between the first predeterminable area and the second predeterminable area.

In the embodiment of the present application, for example, Figure 15 is the target roles and the second preset areas that one embodiment of the application provides Domain is overlapped, and the most big end of target roles in a first direction and the most big end in smallest end and second direction and smallest end exist Schematic diagram in second predeterminable area.As shown in Figure 15, due to 307 He of most big end in target roles 304 in a first direction 305 Most big end 309 and smallest end 310 in smallest end 308 and second direction 306, therefore can be in the second predeterminable area 303 It controls virtual camera and adjusts shooting angle to the direction close to target roles 304, shown with increasing target roles 304 in two dimension Shared area in region, and then make in the most big end 307 and smallest end 308 and second direction 306 on first direction 305 Most big end 309 and smallest end 310 remove the second predeterminable area 303, to make 303 weight of target roles 304 and the second predeterminable area Conjunction and the most big end 307 on first direction 305 and most big end 309 and smallest end in smallest end 308 and second direction 306 310 between the first predeterminable area 302 and the second predeterminable area 303.

If step S550, the described target roles are overlapped with second predeterminable area and the most big end on the first direction With in smallest end and second direction most big end and smallest end in first predeterminable area, then judge the target roles Whether most big end and smallest end in said first direction and the most big end in second direction and smallest end are described second Outside predeterminable area.It should be noted that the judgement in the step could be explained above later, therefore herein It is not repeating.

Step S560, if it is not, then adjusting shooting angle or the camera site of the virtual camera, so that the target angle Color is overlapped with second predeterminable area and the maximum in most big end and smallest end and second direction on the first direction End and smallest end are between first predeterminable area and second predeterminable area.It should be noted that due to the process Through being explained above, therefore do not repeating herein.

It should be noted that being overlapped in target roles with the second predeterminable area and most big end and smallest end on first direction And the most big end in second direction and smallest end be between the first predeterminable area and second predeterminable area, not to virtually taking the photograph The shooting angle of camera and camera site adjust.

In the following, by process of the citing to the rotation angle for the shooting angle for calculating virtual camera is illustrated.

If target roles are overlapped with the second predeterminable area, and only the smallest end of target roles in a first direction is pre- first If outside region, then controlling the direction rotary taking angle of the smallest end of virtual camera in a first direction to target roles, making The smallest end of target roles in a first direction enters the boundary of the first predeterminable area just, the shooting angle of virtual camera The calculating process for rotating angle is as follows:

As shown in figure 16, three-dimensional perpendicular coordinate system is constructed in the view centrum of the virtual camera in three-dimensional virtual world, Wherein, X-axis, Y-axis, Z axis be mutually perpendicular to and, Z axis is vertical with the hither plane of view centrum and far plane, the plane that X-axis and Y-axis are constituted It is parallel with hither plane and far plane.

Determine coordinate (nx, ny, nz) of the smallest end N1 of target roles in a first direction in three-dimensional perpendicular coordinate system, Determine coordinate (ox, oy, oz) of the virtual camera in three-dimensional perpendicular coordinate system；

Calculate target roles smallest end N1 in a first direction and virtual camera in three-dimensional perpendicular coordinate system away from From L1:

The normal 601 and virtual camera and target roles for calculating the view centrum of virtual camera are in a first direction The angle a1 of the line of smallest end N1:

Determine coordinate of the intersection point T1 of the negative direction of the first predeterminable area and first direction in three-dimensional perpendicular coordinate system The intersection point T1 of the negative direction of first predeterminable area and first direction is moved to point T2 as shown in Figure 16 by (tx1, ty1, tz1) (tx2, ty2, tz2) can make the smallest end N1 of target roles in a first direction move to the boundary of the first predeterminable area.Due to During rotation, the first predeterminable area and the second predeterminable area also rotate with the shooting angle of virtual camera, and by It is millisecond rank in the monitoring frequency of target roles hereinbefore, the distance of far plane and virtual camera is larger in addition, because The angle that the shooting angle of this virtual camera rotates every time is all very small, therefore the first predeterminable area and second can be preset The rotation in region can approximation regard translational motion as.Based on this, the coordinate value of the X-axis of point T2 (tx2, ty2, tz2) are as follows: tx2= tz1*tan(a1)；

Virtual camera is calculated during rotation, the intersection point T1 of the negative direction of the first predeterminable area and first direction with The amount of first predeterminable area translation is S1, wherein S1=tx1-tx2；

The rotation angle a2 of the shooting angle of virtual camera are as follows:

It should be noted that in other cases, since the calculating of the rotation angle of the shooting angle of virtual camera is former Reason is identical as above-mentioned principle, therefore is not repeating herein.

In the following, by being illustrated to the process for the distance for calculating the separate or close target roles of virtual camera.

Due to virtual camera far from or close to the distance of target roles and the area change amount of target roles and virtually The visual angle of video camera is (i.e. as the angle b) in Figure 17 is related.Based on this, it is separate or close to target roles to calculate virtual camera The process of distance may include:

The current area V1 under current state of target roles is calculated, target of the target roles under dbjective state is calculated Area V2；

The distance d of the separate or close target roles of virtual camera are as follows:

It should be noted that due to the detection of target roles state be in real time, though virtual camera whether During adjustment, the state of target roles is measured in real time, if virtual camera adjustment during and target Role does not adjust also to dbjective state, if state changes in the state and adjustment before the adjustment of target roles, pause is worked as It is preceding adjusted to the adjustment virtually imaged and according to target roles during changed state redefine virtual camera New adjustment mode, and the basis of the state of the virtual camera before pause is according to the new virtual camera shooting of adjustment mode adjustment Machine.For example, if target roles are overlapped with the second predeterminable area, and only the smallest end on first direction in the second predeterminable area, Most big end in most big end and second direction and smallest end on first direction is in the second predeterminable area and the first predeterminable area Between, then the opposite direction rotary taking angle of smallest end of the virtual camera on first direction is controlled, if at rotary taking angle During degree, detect that smallest end in a first direction does not move out the second predeterminable area, the most big end on first direction also It has moved into the second predeterminable area, the most big end and smallest end in second direction are in the second predeterminable area and the first predeterminable area Between, then the shooting angle for the virtual camera that stops rotating, control virtual camera makes to close to the movement of the direction of target roles Target roles are overlapped and the maximum in the smallest end on first direction and most big end and second direction with the second predeterminable area End and smallest end are between the first predeterminable area and the second predeterminable area.

In conclusion judge target roles whether be overlapped with the second predeterminable area and target roles in a first direction most Most big end in small end and most big end and second direction and smallest end between the first predeterminable area and the second predeterminable area, if It is no, then shooting angle and/or the camera site of virtual camera are adjusted, in other words, in target roles and the second predeterminable area weight Under the premise of conjunction, if ensure smallest end in the smallest end and most big end and second direction of target roles in a first direction and Most big end is between the first predeterminable area and the second predeterminable area, then does not adjust the shooting angle and/or bat of virtual camera It acts as regent and sets, i.e., ensuring that target roles under the premise of will not remove two-dimensional display area, provide biggish for target roles Space, so that the control to target roles is more flexible, expansibility is strong, and the user experience is improved, and virtual camera It need not be moved in real time according to the movement of target roles；In addition, since the first predeterminable area and the second predeterminable area can be set In any region of two-dimensional display area, therefore, the flexibility of the control to target roles is further increased.

Corresponding above-mentioned display control method is applied to pair the embodiment of the present application also provides a kind of display control unit The control of virtual camera in three-dimensional virtual world, the virtual camera are accounted for according to the screen of the display screen in user terminal Than mapping out two-dimensional display area in the display screen, the virtual camera claps it in the three-dimensional virtual world The virtual scene taken the photograph is mapped in two-dimensional display area, and the virtual scene includes target roles, and Figure 18 is the implementation of the application one The structural schematic diagram for the display control unit that example provides.As shown in figure 18, which may include: the first setup module 1801, the second setup module 1802, determining module 1803, judgement adjustment module 1804, in which:
