< general concept >

In the rendering display of the three-dimensional scene, there may be a case where the three-dimensional scene is occluded by other upper layer graphics. For example, when a three-dimensional scene is displayed by the terminal device in fig. 1, a dialog box related to the exit operation is also displayed on the upper layer of the three-dimensional scene. In addition, the character in the three-dimensional scene is displayed with a "player: zhang three is the text of the content, and the text is also always positioned at the upper layer of the three-dimensional scene. Areas in the three-dimensional scene which are shielded by upper-layer graphics such as interface graphics and overhead characters cannot be displayed on a screen finally, if the areas are avoided being rendered in advance, corresponding hardware overhead can be reduced, and rendering performance is improved.

In addition, a test mechanism for cutting off the fragments in the three-dimensional scene exists in the rendering display. As shown in fig. 2, for a fragment in a three-dimensional scene, a depth test, a template test, and the like may be performed in sequence, and the fragment passing the test may be finally displayed on a screen after subsequent processing. For a fragment that has not been subjected to a certain test, the fragment is discarded, i.e. it is not further processed. The above test is performed based on buffer data corresponding to the three-dimensional scene, e.g. based on depth values in a depth buffer, template values in a template buffer, etc. By setting and modifying the values of these data, it is possible to control whether the corresponding fragment is rendered to the screen.

Based on the two aspects, the embodiment of the invention provides a rendering method, which includes the steps of firstly obtaining an area in a three-dimensional scene, which is shielded by an upper layer of graphics, and then setting visibility data corresponding to the shielded area, so that the area is omitted during rendering, thereby avoiding unnecessary overhead and improving rendering performance.

< method examples >

The present embodiment provides a method for rendering a three-dimensional scene, which is implemented by, for example, the terminal device 100 in fig. 1. As shown in fig. 4, the method includes the following steps S1100-S1300:

step S1100, acquiring an area in the three-dimensional scene, which is shielded by the upper layer graph.

The three-dimensional scene in the present embodiment is a stereoscopic image displayed by a three-dimensional technique, for example, a stereoscopic picture in a game, and for example, a stereoscopic picture in a merchandise display.

In one example, the display processing of the three-dimensional scene is divided into two stages of modeling and rendering, wherein the modeling is to establish a three-dimensional model containing key parameters of an object, and the rendering is to increase the effects of visual angle, shadow, texture and the like of the established three-dimensional model and display the three-dimensional model on a screen.

In this embodiment, the upper layer graphics are graphics that are displayed on the three-dimensional scene and that can block the three-dimensional scene, for example, interface graphics in the user interface, overhead characters of a character in the three-dimensional game, and a "small window" for video playing. The upper layer pattern in this embodiment may be a two-dimensional pattern or a three-dimensional pattern, which is not limited herein.

In this embodiment, due to the occlusion of the three-dimensional scene by the upper layer graphics, the occluded region becomes invisible or almost invisible when finally displayed on the screen.

In an example, the specific implementation of acquiring the area in the three-dimensional scene, which is blocked by the upper layer graph, is as follows: and obtaining an area shielded by the upper layer graph in the three-dimensional scene according to the RGBA information of the pixels in the upper layer graph.

A pixel is the smallest unit or element that is indivisible in an image. Each pixel in the upper layer graph has RGBA information corresponding thereto, where R represents Red (Red), G represents Green (Green), B represents Blue (Blue), and a represents opacity (Alpha).

In this example, since the upper layer graph is always located on the three-dimensional scene, whether the three-dimensional scene corresponding to the pixel position is visible or not can be judged according to the RGBA information of the pixel in the upper layer graph, that is, the occlusion relationship between the upper layer graph and the three-dimensional scene is obtained.

In a more specific example, the area of the three-dimensional scene that is occluded by the upper layer graphics can be obtained according to the opacity of the pixels in the upper layer graphics.

The opacity of a pixel may reflect the degree of transparency or visibility of the pixel itself. For a pixel which is completely transparent in the upper layer of graph, the lower three-dimensional scene can be displayed through the pixel, so that the pixel can not shield the three-dimensional scene. For a pixel in the upper layer of graphics that is completely opaque, the pixel cannot be penetrated by the lower three-dimensional scene, and therefore the pixel can block the three-dimensional scene. For a semitransparent pixel, the shielding condition of the pixel on the three-dimensional scene can be judged according to the specific opacity degree of the pixel.

In this example, the pixel opacity ranges from 0% to 100%. Wherein, an opacity of 0% means that the pixel is completely transparent, an opacity of 100% means that the pixel is completely opaque, and an opacity located between the two means that the pixel is semi-transparent.

In other more specific examples, the region in the three-dimensional scene that is occluded by the upper graphics may also be obtained according to the RGB color information of the pixels in the upper graphics. For example, for a pixel in the upper layer of graphics, whose RGB color is pure black, the pixel is considered to cause occlusion to the underlying three-dimensional scene. The specific judgment standard can be determined by combining the actual situation, and is not limited herein.

After the area in the three-dimensional scene, which is covered by the upper layer graph, is obtained, the following step S1200 is executed:

in step S1200, a value of setting data corresponding to an occluded area of the three-dimensional scene is set as a target value, wherein the setting data is data indicating content visibility, and the target value is such that the area is omitted when rendering the three-dimensional scene.

In the present embodiment, the setting data is data indicating the visibility of the content. For example, when the value of the setting data is the first value, the three-dimensional scene area corresponding to the setting data is visible, that is, the three-dimensional scene area corresponding to the setting data is rendered to the screen. When the value of the setting data is a second value different from the first value, the three-dimensional scene area corresponding to the setting data is invisible, that is, the three-dimensional scene area corresponding to the setting data is not rendered to the screen.

In the present embodiment, the setting data is, for example, depth data in a depth buffer, template data in a template buffer, data indicating content visibility in ray tracing rendering, or the like.

In this embodiment, the target value of the data is set so that the occluded region in the three-dimensional scene is omitted during rendering. For example, the target value is the first numerical value, and the set data corresponding to the occluded area is set as the target value, so that the occluded area is not rendered on the screen, that is, the occluded area is omitted during rendering.

In an example, the setting a value of the setting data corresponding to the occluded area of the three-dimensional scene as a target value includes: acquiring pixels corresponding to the shielded area; searching a numerical value corresponding to each pixel in a buffer area of the three-dimensional scene for storing set data; and modifying each searched numerical value into a target value.

In this example, the area of the three-dimensional scene occluded by the upper layer graphic corresponds to a plurality of pixels, and for each pixel therein, the three-dimensional scene is occluded by the upper layer graphic at that pixel position.

When the area in the three-dimensional scene that is occluded by the upper layer graph is obtained in step S1100, a pixel-by-pixel processing mode may be adopted, that is, each pixel in the three-dimensional scene is traversed, the occlusion condition of the three-dimensional scene corresponding to each pixel position and the upper layer graph is determined, and the pixels that correspond to the three-dimensional scene that are occluded by the upper layer graph are aggregated, so that the area in the three-dimensional scene that is occluded by the upper layer graph is obtained. In the above manner, the pixels corresponding to the blocked area are obtained at the same time.

In this example, the buffer area for storing the setting data of the three-dimensional scene is a special area for storing the setting data in the memory, and includes, for example, a depth buffer area, a stencil buffer area, and the like. By reading and writing the buffer area, the value of the set data corresponding to each pixel can be searched and modified into the target value.

In one example, the setting data in step S1200 is depth data, and the target value in step S1200 is such that the occluded area cannot pass the depth test in the rendering display, i.e. rendering of the occluded area is avoided based on the depth test.

In this example, the depth test is a process of selecting or rejecting display content based on depth data, and can solve the visibility problem at a specific viewing angle caused by mutual occlusion between three-dimensional models.

Referring to fig. 5, the camera (virtual in the rendered display), the P1 plane, and the P2 plane are shown in fig. 5 in sequence from left to right, where the P1 plane and the P2 plane are each models of a three-dimensional scene. A1 and a2 are points lying in the P1 plane and the P2 plane, respectively, and both the a1 point and the a2 point are imaged on pixel a in the camera. The distance from the point A1 to the camera is the depth Z1 from the point A1, and the distance from the point A2 to the camera is the depth Z2 from the point A2. It is readily understood that the point a1 is closer to the camera than the point a2, i.e., Z1 is less than Z2, so the point a1 obscures the point a2 during imaging so that the point a2 is not displayed at pixel a.

For the case shown in fig. 5, the specific procedure of the depth test is, for example: first, the depth data of the corresponding pixel a in the depth buffer (depth buffer) is initially set, for example, to the depth value Max of the far clipping surface. The far clipping plane here is the farthest rendering position relative to the camera, and similarly, the near clipping plane is the closest rendering position relative to the camera. And then, when the specific content of the three-dimensional scene is drawn, comparing whether the depth value of the point to be drawn is smaller than the current depth value in the depth buffer area, if so, drawing the point and updating the depth value in the depth buffer area to the depth value of the point, and if not, discarding the point and not processing the point. For example, when the a1 point is drawn first, the depth value Z1 of the a1 point is compared with the initial depth value Max, and it is easy to know that Z1 < Max, so (the color of) the a1 point is drawn at the pixel a, and the depth value in the above depth buffer is updated to Z1. When the point a2 is redrawn, the depth value Z2 of the point a2 is compared with the current depth value Z1 in the depth buffer, and it is easy to know that Z2 > Z1, so the point a2 is discarded and no drawing is performed. Therefore, points which are close to the camera in the three-dimensional scene can be drawn on the screen through the depth test, and points which are shielded by the points are not drawn on the screen.

In this example, the depth test is applied to occlusion displays of a three-dimensional scene and an upper layer graphic. And for the area which is shielded by the upper layer graph in the three-dimensional scene, setting the numerical value of the depth data in the depth buffer area corresponding to the shielded area as a target value which enables the shielded area not to pass the depth test.

In this example, the value of the depth data in the depth buffer corresponding to the occluded region may be set based on the pixel corresponding to the occluded region. For example, the occluded region includes X, Y, Z pixels, depth data x, y, and z sequentially corresponding to X, Y, Z pixels exist in the depth buffer, and the values of x, y, and z are set as target values, that is, the value setting of the depth data corresponding to the occluded region is realized.

In this example, the target value is a value that makes the occluded region unable to pass the depth test, i.e., the target value makes each pixel corresponding to the occluded region unable to pass the depth test. For example, in the case that the passing condition of the depth test is that the depth value to be tested is smaller than the current depth value in the depth buffer, the target value is selected to be 0, that is, the initial value of the depth data in the depth buffer corresponding to each pixel in the occluded area is set to be 0. Here, the depth data is normalized, and the depth of the near cutting plane is 0 and the depth of the far cutting plane is 1. Thus, because the depth value of each point in the three-dimensional scene is greater than or equal to 0, for each pixel corresponding to the blocked area, the depth value of the point on the corresponding three-dimensional model does not satisfy the passing condition that the depth value is less than 0, and the pixel cannot be drawn on the screen, that is, the pixel cannot pass the depth test.

In this example, the target value may be determined according to a specific test passing condition, and is not limited herein.

In the example, the area which is shaded by the upper layer graph in the three-dimensional scene can be effectively avoided based on the depth test, and the performance consumption is low.

In one example, the setting data in step S1200 is the stencil data in the stencil buffer, and the target value in step S1200 is such that the occluded area cannot pass the stencil test in the rendering display, i.e., rendering of the occluded area is avoided based on the stencil test.

In this example, the template test is a process of accepting or rejecting display content based on template data, and the implementation process is similar to the depth test, and is to compare a template value of a point on the three-dimensional model with a current template value in the template buffer area, and draw a point satisfying a test passing condition onto a corresponding pixel. The template test can be used for realizing the effects of displaying the object frame in the three-dimensional scene and the like. For example, the template value corresponding to the border region of the object is set to 1 in advance, and the template value corresponding to the non-border region is set to another value. And setting the passing condition of the template test as that the template value to be tested is equal to the current template value in the template buffer area, and setting the initial template value in the template buffer area as 1. It is readily understood that only the bezel area passes the stencil test and is drawn to the screen.

In this example, the stencil test is applied to the occlusion display of the three-dimensional scene and the upper graphics. And for the area which is shielded by the upper layer graph in the three-dimensional scene, setting the numerical value of the template data in the template buffer area corresponding to the shielded area as a target value which enables the shielded area not to pass the template test. For example, in the case that the template values of the three-dimensional scene are all greater than 0, and the template test passing condition is that the template value to be tested is equal to the current template value in the template buffer area, the initial value of the template data of the template buffer area corresponding to the occluded area is set to-1. Thus, the occluded area cannot pass the stencil test and is not rendered to the screen.

In this example, rendering of occluded regions can be effectively avoided based on the stencil test, and performance consumption is low.

It should be noted that the setting data may be set as the target value based on any one of the depth test and the stencil test, or may be set as the target value based on both tests, which is not limited herein.

After setting the setting data as the target value, the following step S1300 is executed:

and step 1300, rendering the three-dimensional scene to a screen according to the set data of the set three-dimensional scene.

In this embodiment, the three-dimensional scene is rendered according to the set data of the set three-dimensional scene. It is easy to understand that the area in the three-dimensional scene, which is occluded by the upper graphics, is omitted during rendering, and the area which is not occluded by the upper graphics is rendered to the screen in a normal manner. For the specific rendering situation, reference may be made to the depth test and the template test process involved in the description of the target value, and details are not repeated here.

The rendering method in the embodiment first obtains the area in the three-dimensional scene, which is shaded by the upper layer of graphics, and then sets the visibility data corresponding to the shaded area, so that the area is omitted during rendering, thereby avoiding unnecessary overhead and being beneficial to improving the rendering performance.

The embodiment also provides another rendering method for a three-dimensional scene, which is suitable for a situation where an interface graph and the three-dimensional scene are displayed together, and can be implemented by the terminal device 100 shown in fig. 3 as well. As shown in fig. 6, the method includes the following steps S2100-S2300:

step S2100, acquiring a region shielded by an interface graph in a three-dimensional scene.

In step S2200, a value of setting data corresponding to an occluded region of the three-dimensional scene is set as a target value, where the setting data is data indicating content visibility, and the target value is such that the region is omitted when rendering the three-dimensional scene.

Step S2300, rendering the three-dimensional scene to a screen and rendering the interface graphics to the screen according to the set data of the set three-dimensional scene.

Specific embodiments of steps S2100-S2300 are described above with reference to steps S1100-S1300.

The interface graph in the embodiment is a graph of an interactive interface in human-computer interaction. The interface graphic is displayed over the three-dimensional scene.

In an example, the three-dimensional graphics rendering method provided by the present embodiment further includes: and drawing the interface graph to a rendering target buffer area. At this time, the step of rendering the interface graphic to the screen in step S2300 includes: drawing the interface graphics in the rendering target buffer area to a screen.

In this example, the render-target buffer is a memory area in the render display that may be used to store rendered graphics. The interface graph is firstly drawn to the rendering target buffer area, and then the interface graph in the rendering target buffer area is drawn to the screen, so that the interface graph and the three-dimensional scene can be synchronously displayed on the screen.

In other embodiments, the interface graphics may also be directly drawn on the screen, which is not limited herein.

In this example, step S2100 acquires a region in the three-dimensional scene that is occluded by the interface graph, including: obtaining RGBA information of pixels in the interface graph according to the interface graph in the rendering target buffer area; and obtaining an area which is shielded by the interface graph in the three-dimensional scene according to the RGBA information. That is, in this example, RGBA information of the interface graphic is acquired based on the interface graphic drawn in the rendering target buffer. By the method, the RGBA information of the finally displayed interface graph can be conveniently acquired.

Fig. 7 is an example to explain an implementation process of the three-dimensional scene rendering method in the present embodiment. In the example shown in fig. 7, the interface graphic 7-2 related to the quit operation is displayed on the three-dimensional scene 7-1, and the final display effect is shown as 7-5 in fig. 7. When rendering the three-dimensional scene, firstly, an area 7-3 which is shielded by the interface graph 7-2 in the three-dimensional scene 7-1 is obtained. Firstly, drawing the interface graph 7-2 to a rendering target buffer area, wherein the graph in fig. 7 is only used for demonstrating the rendering process, and does not represent that the related graph is already displayed on a screen, the interface graph 7-2 is a rectangle, a text prompt of whether to quit and selection buttons corresponding to yes and no are displayed, and the opacity of all pixels corresponding to the interface graph 7-2 is 100%, that is, all pixels corresponding to the interface graph are not transparent, and the three-dimensional scene below can be shielded. Accordingly, the region 7-3 in the three-dimensional scene that is occluded by the interface graphic 7-2 can be obtained. The value of the setting data corresponding to the area 7-3 in the three-dimensional scene is modified, for example, the depth value in the depth buffer corresponding to the area 7-3 in the three-dimensional scene 7-1 is modified to 0, so that none of the depth values of the points on the corresponding three-dimensional model satisfies the passing condition that the depth value is less than 0, and cannot be drawn on the screen. And then, rendering the three-dimensional scene according to the set data of the set three-dimensional scene, wherein the obtained rendering result is shown as 7-4, and it can be seen that the area 7-3 shielded by the interface graph 7-2 in the three-dimensional scene is not rendered and is represented as a black area in 7-4. And drawing the interface graph 7-2 in the rendering target buffer area to a screen while rendering the three-dimensional scene, so that the three-dimensional scene 7-1 and the interface graph 7-2 are jointly displayed, and the final rendering result is shown as 7-5.

The present embodiment also provides another method for rendering a three-dimensional scene, where the rendering in the method is ray tracing rendering, and the method may also be implemented by the terminal device 100 shown in fig. 3, and includes the following steps S3100 to S3300:

step S3100, acquiring a region shielded by an upper layer graph in the three-dimensional scene.

The upper layer graphics may be, for example, interface graphics, or overhead characters of characters in a game application, and is not limited herein.

In step S3200, a value of setting data corresponding to a blocked region of the three-dimensional scene is set as a target value, where the setting data is data indicating content visibility in ray tracing rendering, and the target value is such that the region is omitted when rendering the three-dimensional scene.

And S3300, rendering the three-dimensional scene to a screen and rendering the interface graph to the screen according to the set data of the set three-dimensional scene.

Specific embodiments of steps S3100-S3300 can be found above in the description of steps S1100-S1300.

In this embodiment, the ray tracing rendering is a rendering method of a three-dimensional scene, and a more accurate three-dimensional display effect can be achieved by obtaining the color of the three-dimensional model displayed by each pixel according to the light from the observer.

In this embodiment, the setting data is data indicating the visibility of content in the ray tracing rendering, and whether to perform ray tracing on the pixel may be determined according to the setting data. For example, in one example, the setting data may be set to 0 or 1, the setting data corresponding to a pixel is set to 1, which indicates that the ray tracing process is performed on the pixel, and the setting data corresponding to a pixel is set to 0, which indicates that the ray tracing process is not performed on the pixel. It is easily understood that in this example, the target value of the area where the three-dimensional scene is occluded by the upper layer graphics is 0, and the target value of the area where the three-dimensional scene is not occluded is 1. Therefore, the shaded area can be avoided being rendered in ray tracing rendering, and the rendering performance of ray tracing rendering is improved.

The present embodiment further provides another rendering method for a three-dimensional scene, for example, implemented by the terminal device 100 shown in fig. 3, where the method includes the following steps S4100-S4400:

step S4100, in response to the set display refresh event, loading data of the next frame of three-dimensional scene matched with the user operation.

In an example of applying the rendering method of the present embodiment to rendering of a three-dimensional game scene, the set display refresh event may include at least one of expiration of a refresh time determined according to a set frame rate, reception of a refresh instruction triggered externally, and restoration of a network connection with a server, for example.

For example, if the frame rate is set to 60 frames/second, that is, if 60 frames are refreshed per second, when the refresh time determined according to the frame rate is up, the data of the next frame of three-dimensional scene matched with the user operation is loaded for rendering, so as to implement the refresh display.

For another example, when the user triggers a refresh command through a refresh button set on the game interface, the terminal device 100 also loads the data of the next frame of three-dimensional scene matching with the user operation in response to the refresh command to perform rendering, so as to implement refresh display.

For another example, after the terminal device 100 is disconnected from the server due to a network abnormality, the terminal device 100 acquires the latest basic data from the server after restoring the network connection with the server, and at this time, renders the data describing the next frame of the three-dimensional scene matching the user operation based on the basic data to implement the refresh display.

In an example, the three-dimensional scene in this embodiment is a three-dimensional game scene, and the user operation includes any one or more of a keyboard operation, a mouse operation, a touch screen operation, a limb sensing operation, and a gravity sensing operation.

In this embodiment, a specific user operation may cause a change in the next three-dimensional scene and/or the next interface graphics. For example, as shown in fig. 8, in 8-1, only a three-dimensional scene exists in the currently displayed content, and at this time, the user performs a tap key operation, which can invoke the exit interface shown in 8-2, and the exit interface is displayed as the next frame of interface graphics, that is, the next frame of interface graphics changes from the existing interface graphics. For another example, if the user operates a game character to move in a three-dimensional scene, the next three-dimensional scene will be related to the movement position and movement direction of the game character, i.e., will match the user operation.

Step S4200, according to the loaded data, obtaining an area in the next frame of three-dimensional scene, which is shielded by the next frame of interface graphics.

In the event that the user action would change the interface graphics, the next frame of interface graphics would also match the user action.

In step S4300, a value of setting data corresponding to the region of the next three-dimensional scene is set as a target value, where the setting data is data indicating content visibility, and the target value is such that the region is omitted when rendering the next three-dimensional scene.

Step S4400, rendering the next three-dimensional scene to the screen according to the set data of the set next three-dimensional scene, and rendering the next interface image to the screen.

The refreshing of the display content of the next frame will be completed, through step S4400.

Steps S4200-S4400 can be as described above for steps S1100-S1300.

The present embodiment further provides another method for rendering a three-dimensional scene, for example, the method is implemented by the terminal device 100 shown in fig. 3, and the method includes the following steps S5100 to S5400:

step S5100, in response to the set display refresh event, obtains the next frame of interface graphics matched with the user operation.

In this embodiment, a specific user operation corresponds to a specific interface graphic. For example, as shown in FIG. 8, the exit interface shown in FIG. 8-2 corresponds to a user tapping a button operation in FIG. 8-1.

In this embodiment, the terminal device, in response to a user operation, acquires interface graphic information corresponding to the user operation according to a preset corresponding relationship, for example, acquires parameters such as content, position, size, opacity, and the like of an interface graphic.

Step S5200, acquiring an area in the next three-dimensional scene, which is covered by the next interface image.

In the case where the user operation would change the three-dimensional scene, the next frame of the three-dimensional scene would also match the user operation.

In step S5300, a value of setting data corresponding to the area of the next frame of three-dimensional scene is set as a target value, where the setting data is data indicating content visibility, and the target value is such that the area is omitted when rendering of the next frame of three-dimensional scene is performed.

And step S5400, rendering the next frame of three-dimensional scene to a screen according to the set data of the next frame of three-dimensional scene after setting, and rendering the next frame of interface graphics to the screen.

Continuing with the example shown in fig. 8, before performing display refresh, if the user touches the exit operation triggered by the key, when performing display refresh, the mobile terminal 100, according to the detected user operation of the key, acquires an interface graphic corresponding to the operation as a next frame interface graphic, for example, an exit interface shown in 8-2 corresponding to the operation, and when performing rendering of the next frame, acquires an area in the next frame three-dimensional scene that is blocked by the exit interface, to set a value of setting data corresponding to the area of the next frame three-dimensional scene as a target value, so that the area is omitted when performing rendering of the next frame three-dimensional scene. In this example, after the rendering display of the next frame of three-dimensional scene and the next frame of interface graphics is completed according to step S5400, a display screen of 8-3 is obtained.

The above steps S5200 to S5400 can be referred to as the above description of steps S1100 to S1300.

The present embodiment further provides another rendering method for a three-dimensional scene, for example, implemented by the terminal device 100 shown in fig. 3, where the method includes the following steps S6100 to S6300;

in step S6100, an invisible area of the three-dimensional scene is acquired.

In one example, an invisible region of a three-dimensional scene is acquired, including any one or combination of any of: acquiring an area in a three-dimensional scene, which is shielded by an upper layer of graph; acquiring a region corresponding to an object with an imaging size smaller than a preset threshold value in a three-dimensional scene; and acquiring a non-attention area of a current visual angle subject in the three-dimensional scene.

In this example, the area in the three-dimensional scene that is occluded by the upper layer graphics is obtained, which can be referred to the above description of step S1100.

In this example, the imaged size is the size of the image on the screen of an object in the three-dimensional scene. The imaging size of the object can be obtained according to the distance from the object to the screen, the size of the object itself and other information. The preset threshold is a preset imaging size. When the imaging size of the object is smaller than the preset threshold, the size of the image corresponding to the object is significantly smaller than the size of the image corresponding to the entire three-dimensional scene, and the region corresponding to the object may be considered as an invisible region. During three-dimensional rendering, rendering calculation is not needed for the area corresponding to the object, and processing modes such as direct background display and the like can be adopted.

In this example, the current perspective subject is, for example, a person viewing a three-dimensional scene from a main perspective. For perspective subjects with different characters, identities, etc., the regions of interest (or regions of interest) when viewing a three-dimensional scene are different. For example, for a female person, details of a flower, a butterfly, and the like in a scene are generally interested in the female person, but a male person generally does not pay special attention to the details, so that a region corresponding to the flower, the butterfly, and the like can be considered as a non-attention region of the male person. During three-dimensional rendering, rendering calculation is not needed in a non-attention area of the current visual angle main body, and processing modes such as direct background display and the like can be adopted.

In one example, acquiring an invisible region of a three-dimensional scene includes: providing a setting entrance for setting the invisible area; an invisible area input by the setting entry is acquired.

In this example, the user can make custom settings for the invisible area. For example, the user may cancel the particle effect in the frame, i.e., set the region corresponding to the particle in the three-dimensional scene as the invisible region. The invisible area can be directly obtained according to data input by the user through the setting portal.

In one example, acquiring an invisible region of a three-dimensional scene includes: providing a setting entrance for setting a visible area in a three-dimensional scene; acquiring a visible area input through a setting entrance; from the visible region, an invisible region is obtained.

In this example, the user may perform a custom setting on the visible region, and the portions outside the visible region are all invisible regions, that is, the user performs a reverse setting on the invisible regions.

In step S6200, a value of setting data corresponding to the invisible area of the three-dimensional scene is set as a target value, wherein the setting data is data representing content visibility, and the target value is such that the invisible area is omitted when rendering the three-dimensional scene.

And S6300, rendering the three-dimensional scene to a screen according to the set data of the set three-dimensional scene.

Steps S6200-S6300 described above can be referred to the description of steps S1200-S1300 above.
