Referring to fig. 2, a flowchart of a three-dimensional object rotation method according to an exemplary embodiment of the present application is shown. The method may be performed by a computer device; wherein the computer device may be the computer device 10 shown in fig. 1 described above. The method may include the following steps.
In the embodiment of the application, the computer device may display the interactive interface in the touch screen through the installed and run application program.
The three-dimensional object refers to a three-dimensional virtual object existing in a three-dimensional virtual environment, for example, the three-dimensional object may be a three-dimensional object or a three-dimensional character, etc.
In this embodiment of the application, the computer device may detect, in real time, a touch operation of a user in an interactive interface, where an initial number of touch points corresponding to the touch operation is 2, that is, when a three-dimensional object is rotated, the user first performs the touch operation in a touch screen by a two-point touch manner.
In the embodiment of the present application, in the subsequent rotation process, the user may keep the operation of two-point touch, or change from the two-point touch to the single-point touch, where the two-point touch/the single-point touch are used to determine the rotation axis of the target three-dimensional object, the touch operation may be a touch sliding operation, and the sliding condition (such as the sliding direction, the sliding distance, the sliding speed, and the like) of the touch sliding operation is used to determine the rotation angle of the target three-dimensional object.

Referring to fig. 3, a flowchart of a three-dimensional object rotation method according to an exemplary embodiment of the present application is shown. The method may be performed by a computer device; wherein the second computer device may be the computer device 10 shown in fig. 1 described above. The method may include the following steps.
In an embodiment of the application, a computer device may display an interactive interface and may display at least one three-dimensional object in the interactive interface.
Wherein, the interactive interface can be a two-dimensional view interface, and the two-dimensional view interface can be an interactive interface displayed through a two-dimensional view screen. The computer device may display an interactive interface on a two-dimensional view screen and at least one three-dimensional object on the two-dimensional view interface.
In one possible implementation, the computer device may be a terminal device, which may be a smartphone.
For example, please refer to fig. 4, which shows a schematic diagram of an interactive interface according to an embodiment of the present application. As shown in fig. 4, the computer device (smartphone) displays a UI interface, which may be the above-mentioned interactive interface, on which a virtual world 40(virtual world) and at least one three-dimensional object 41(3D object) are displayed, and the UI interface may be displayed on a display screen, which may be a multi-touch screen 42(multi-touch screen), and the multi-touch screen 42 may support the computer device to receive a multi-shot signal instruction when the computer device is touched at multiple points. The user can view the virtual world 40 and the three-dimensional object 41 therein through the UI interface.
In this embodiment of the application, the computer device may detect the touch points in the interactive interface, and may determine the current number of the currently detected touch points in the interactive interface because the initial number of the touch points in the interactive interface is 2, where one of the two cases is to maintain the initial number, that is, the current number of the detected touch points is still 2, and the other is to reduce the touch points, that is, the current number of the detected touch points is 1.
In a possible implementation manner, the computer device periodically detects the touch point in the interactive interface, or the computer device detects the touch point in the interactive interface in real time.
That is, when the computer device displays the interactive interface and the interactive interface includes at least one three-dimensional object supporting rotation, the computer device may periodically or in real time detect whether there are touch points in the interactive interface and determine the current number of touch points.
Since the computer device displays the interactive interface through the multi-touch screen, the computer device may detect a plurality of touch points acting on the multi-touch screen.
In an embodiment of the application, the computer device may determine a rotation axis currently directed to the target three-dimensional object according to the current number of detected touch points.
Wherein the target three-dimensional object may be one of at least one three-dimensional object displayed on the interactive interface, and the target three-dimensional object may be a three-dimensional object currently supported for rotation.
In one possible implementation manner, when a three-dimensional object is displayed on the interactive interface, the computer device may directly determine the three-dimensional object as a target three-dimensional object, and the computer device may automatically lock the target three-dimensional object in the three-dimensional object. When at least two three-dimensional objects are displayed on the interactive interface, the computer device may randomly select one of the at least two three-dimensional objects as a target three-dimensional object, or may select one of the at least two three-dimensional objects as the target three-dimensional object according to a position of a currently detected touch point.
When the current number of the touch points is 2 and continuous clicking operation occurs at one touch point of the 2 touch points, switching the target three-dimensional object among the n three-dimensional objects under the condition that the number of the at least one three-dimensional object is n and n is an integer greater than or equal to 2.
That is to say, if at least two three-dimensional objects currently exist in the interactive interface and the computer device detects that at least two touch points currently exist, a target three-dimensional object of the at least two three-dimensional objects can be determined according to the positions of the two detected touch points, and when the computer device receives a continuous click operation occurring at the position of any one of the at least two touch points, the current target three-dimensional object is switched, that is, one of the remaining three-dimensional objects can be replaced by the target three-dimensional object.
For example, the current target three-dimensional object may be displayed in a central region of the interactive interface, the current remaining three-dimensional objects may be displayed in an edge region of the interactive interface, and the target three-dimensional object in the central region may be displayed in a larger size than the current remaining three-dimensional objects in the edge region. When the computer device detects that the current number of the touch points is 2, and receives that the continuous clicking operation occurs at the position of any one of the 2 touch points, one of the three-dimensional objects in the edge area can be displayed in the center area, and the three-dimensional object in the center area before is displayed in the edge area, so that the current target three-dimensional object is switched, and if the current switched target three-dimensional object still needs to be replaced, the continuous clicking operation continues to be received at the position of any one of the 2 touch points until the three-dimensional object displayed in the center area is the finally determined target three-dimensional object.
In addition, when the computer device detects that the current number of the touch points is 2 and receives that a continuous click operation occurs at the position of any one of the 2 touch points, it may be preferentially determined whether a three-dimensional object exists in the direction of the touch point where the continuous click operation occurs, and if a three-dimensional object exists in the direction, the three-dimensional object in the edge area of the direction is preferentially switched with the three-dimensional object in the central area. Through the convenient operation, the step of rapidly switching the target three-dimensional object in the presence of a plurality of three-dimensional objects in the interactive interface can be realized, the efficiency of determining the target three-dimensional object is greatly improved, and meanwhile, additional touch operation is not needed, so that the convenience of operation is improved.
In one possible implementation, when the computer device detects that the current number of touch points is an initial number, i.e., two touch points, then it may be determined that the axis of rotation currently directed to the target three-dimensional object may be the axis of rotation perpendicular to the screen. When the computer device detects that the current number of touch points becomes one touch point, then it may be determined that the axis of rotation currently directed to the target three-dimensional object may be parallel to the axis of rotation of the screen.
Wherein, when the current number of detected touch points is 2, the computer device may determine that the rotation axis of the target three-dimensional object may be perpendicular to the screen, and the rotation axis may pass through the centroid of the target three-dimensional object or the rotation axis may pass through the midpoint of the connecting line between the two currently detected touch points. When the current number of detected touch points changes to 1, the computer device may re-determine a rotation axis currently directed to the target three-dimensional object, the re-determined rotation axis may be a rotation axis parallel to the screen, and the rotation axis may be a perpendicular bisector of the target line or an axis perpendicular to the target line and passing through a centroid of the target three-dimensional object. The target connection line may be a connection line between 2 touch points at a time before one of the 2 touch points disappears.
And step 304, when the touch point moves, the control target three-dimensional object rotates according to the rotating shaft.
In this embodiment of the present application, when the touch point moves, the computer device may control the target three-dimensional object to rotate according to the determined rotation axis.
The method comprises the steps of determining a rotating shaft which is currently aimed at a target three-dimensional object according to the current number of touch points detected by computer equipment, and controlling the target three-dimensional object to rotate according to the determined rotating shaft when the touch points move.
In one possible implementation, when the touch points move and the current number of the touch points is 2, the control target three-dimensional object rotates according to a rotation axis perpendicular to the screen.
That is, when the current number of trigger points is 2, the rotation axis may be determined to be an axis perpendicular to the screen, and when one or both of the two touch points move, the computer device may control the target three-dimensional object to rotate according to the determined rotation axis.
The rotation angle of the target three-dimensional object and the rotation angle of the connection line of the 2 touch points can be in positive correlation.
That is to say, the rotation angle of the target three-dimensional object may be a rotation angle of a connection line of the 2 touch points, or the rotation angle of the target three-dimensional object may be a product of the rotation angle of the connection line of the 2 touch points and a fixed ratio, that is, the computer device may process the rotation angle of the connection line of the 2 touch points according to the fixed ratio to obtain the rotation angle of the target three-dimensional object.
Or, the above ratio may be a dynamically changing ratio, and the numerical value of the ratio may be related to the rotation speed of the connection line of 2 touch points, that is, when the rotation speed of the connection line of 2 touch points is relatively high, the numerical value of the corresponding ratio is relatively high, and when the rotation speed of the connection line of 2 touch points is relatively low, the numerical value of the corresponding ratio is relatively low.
For example, fig. 5 is a schematic view of determining a rotation angle according to an embodiment of the present application. As shown in fig. 5, A, B are the current two touch points, a ' is the touch point after a shift, B ' is the touch point after B shift, and in the first case 51a, the rotation angle may be the angle of the acute angle AOA '; in the second case 51b, the rotation angle may be the angle of the obtuse angle AOA'; in the third case 51c, the rotation angle may be the difference between 360 degrees and the angle of the acute angle AOA'; in the fourth case 51d, the rotation angle may be the difference between 360 degrees and the angle of the obtuse angle AOA'.
Illustratively, fig. 6 is a flowchart of a two-finger operation according to an embodiment of the present application. As shown in fig. 6, if the target three-dimensional object needs to be rotated 90 degrees around the z-axis perpendicular to the screen, the gesture suggested to the user for manipulating may be to rotate around the axis perpendicular to the screen, the user places two fingers on the screen to form touch points on the screen (S61), at this time, it may be determined that the rotation axis passes through the center of a connecting line between the touch points of the two fingers, and the rotation axis is also perpendicular to the connecting line between the two fingers (S62), the rotation angle of the target three-dimensional object around the z-axis may be changed by performing a clockwise or counterclockwise rotation movement on the two fingers (S63), when the rotation angle reaches the expected 90 degrees, that is, after the rotation angle is sufficient, the rotation movement of the two fingers may be stopped, and the contact between the two fingers and the screen is released (S64), and the rotation of the target three-dimensional object is completed this time. Fig. 7 is a schematic view of a two-finger operation screen display according to an embodiment of the present application. As shown in fig. 7, in the first interactive interface 71, the touch points of the two fingers with respect to the target three-dimensional object are determined, in the second interactive interface 72, the two fingers are controlled to rotate clockwise around the z-axis, so that the target three-dimensional object can be controlled to rotate clockwise around the z-axis, and in the third interactive interface 73, when the target three-dimensional object rotates to 90 degrees, the two fingers can be released, so that the operation of controlling the target three-dimensional object to rotate by the two fingers is finished.
In another possible implementation manner, when the touch points move and the current number of the touch points is 1, the target three-dimensional object is controlled to rotate according to a rotation axis which is parallel to the screen and perpendicular to the target connecting line. The target connection line may be a connection line between 2 touch points at a time before one of the 2 touch points disappears. The rotation angle of the target three-dimensional object may be in positive correlation with the moving distance of the touch point in the current screen.
The rotation angle of the target three-dimensional object may be a product of a ratio of a distance of the current touch point moving toward the vanished touch point to a distance of the target connection line and 180 degrees. Or, the rotation angle of the target three-dimensional object may also be a product of a ratio of a distance of the current touch point moving toward the vanished touch point to a distance of the target link line, and 360 degrees or 270 degrees.
In a possible case, if the current touch point moves towards the direction of the disappeared touch point and exceeds the range of the target connecting line, the rotation angle can be determined to be 0 degree; or, if the current touch point moves in the opposite direction of the disappeared touch point and exceeds the position of the original current touch point, the rotation angle may be determined to be 0 degree.
For example, fig. 8 is a schematic view of the rotation angle determination involved in the embodiment of the present application. As shown in fig. 8, in the first case 81a, if the point a is a vanishing touch point, the point B is a current touch point, and the point B' is a current touch point after movement, the calculation formula of the rotation angle of the target three-dimensional object can be as follows,
in the second case 81B, the rotation angle is 0 degrees since B' is beyond BA after moving in the direction of a. In the third case 81c, the rotation angle is 0 degrees at this time, since B' moves to B and exceeds the range AB.
Illustratively, fig. 9 is a flow chart of a single finger operation involved in an embodiment of the present application. As shown in fig. 9, if it is required to rotate the target three-dimensional object by a certain angle around a rotation axis parallel to the screen, the gesture suggested to the user for manipulating may be to rotate around an axis parallel to the screen, the user puts two fingers on the screen to form touch points on the screen (S91), at which time the rotation axis passing through the center of the connecting line between the touch points of the two fingers and being also perpendicular to the connecting line between the two fingers (S92), and then releases one of the fingers, i.e., leaves the screen, and moves the finger still contacting the screen toward the other finger (S93), the rotation angle of the target three-dimensional object rotating around the rotation axis parallel to the screen may be changed, when the rotation angle reaches a desired angle, i.e., when the rotation angle is sufficient, the movement of the finger may be stopped, and the contact between the finger and the screen is released (S94), and finishing the rotation of the target three-dimensional object. Fig. 10 is a schematic view of a display of a single-finger operation screen according to an embodiment of the present application. As shown in fig. 10, in the first interactive interface 1001, touch points of two fingers with respect to a target three-dimensional object are determined, in the second interactive interface 1002, one of the fingers is released to leave the screen, the other finger is moved in the direction of the upper finger, the rotation axis at this time is determined as a perpendicular bisector of a line connecting the two fingers before the release of the finger, and the rotation angle of the target three-dimensional object is controlled by controlling the distance of the upward movement of the single finger, and in the third interactive interface 1003, when the target three-dimensional object is rotated to 90 degrees, the finger can be released, and the operation of rotating the target three-dimensional object by the single finger is ended.
In a possible implementation manner, since the initial number of the touch points is 2, firstly, the computer device performs a two-finger operation, the target three-dimensional object is controlled to rotate according to a rotation axis perpendicular to the screen through the two-finger operation, and then when the rotation angle in the direction reaches a requirement, the target three-dimensional object is controlled to rotate according to a rotation axis parallel to the screen through a one-finger operation until the rotation angle in the direction reaches the requirement, if the rotation angle rotating according to the rotation axis perpendicular to the screen still needs to be continuously adjusted at this time, the rotation angle of the target three-dimensional object can be controlled by changing to the two-finger operation again.
Illustratively, fig. 11 is a flowchart of a target three-dimensional object rotation control according to an embodiment of the present application.
