Depending on the context, the word "if" as used herein can be interpreted as "at the time of" or "when" or "in response to determining."

First, the terminology involved in one or more embodiments of the present application will be explained.

Virtual texture (VT): It is a texture technology scheme that allows large-scale rendering of texture data in real time and puts the whole texture data into the video memory for continuous sampling through virtual mapping.

Pre-filtered texture map (Mipmap): is a smaller version of texture image pre-filtering, representing different levels of detail (LOD) of the texture, usually stored in a series of continuously shrinking texture objects, these textures are called mipmap chains, each Each level will be half smaller than the previous level.

In the present application, a texture mapping processing method is provided, and the present application also relates to a texture mapping processing apparatus, a computing device, and a computer-readable storage medium, which will be described in detail in the following embodiments.

1 shows a flowchart of a texture mapping processing method provided according to an embodiment of the present application, which specifically includes the following steps:

Step 102: Receive a texture processing instruction for the target texture.

In the process of creating a virtual scene, there will be situations in which the stereoscopic model is mapped to generate a corresponding virtual scene. The virtual scene includes but is not limited to game scenes, animation scenes, movie special effects scenes, VR scenes, and so on.

In a virtual scene, the virtual camera is often zoomed in or zoomed out. For example, for the same object, when the distance between the virtual lens and the object is different, the details of the object will be different. When the virtual lens is closer to the object, it needs to show more details of the object. When an object is far away, the object may only appear as a black dot. The difference between the distance between the virtual camera and the object is applied to texture filtering. Therefore, textures are rendered at different resolutions depending on the distance from the virtual lens.

Based on this, it is necessary to create a multi-resolution (multi-size) pre-filtered texture map (mipmap) for the texture. The mipmap is currently the most effective way to solve the relationship between texture resolution and viewpoint distance. In the method provided by this application, the texture processing instruction specifically refers to an instruction for generating a multi-resolution mipmap for a texture, and the target texture is a texture that needs to generate a multi-size pre-filtered texture map.

In a specific embodiment provided in this application, taking the target texture as the texture P as an example, a texture processing instruction for the texture P is received, and the texture processing instruction is used to generate a multi-sized mipmap of the texture P.

Step 104: Perform virtual texture processing on the target texture in response to the texture processing instruction to obtain a pre-filtered texture map set corresponding to the target texture.

Wherein, the pre-filter texture map set includes pre-filter texture maps of various sizes.

A virtual texture (VT) is a texture technology scheme that allows real-time mass rendering of texture data and places the whole texture data into the video memory for continuous sampling through virtual mapping. By processing the virtual texture of the target map, a series of pre-filtered texture maps can be generated from the target map, and stored in the corresponding texture objects whose size is continuously reduced to obtain the pre-filtered texture map set corresponding to the target map, and the pre-filtered texture A collection of maps can also be a chain of mipmaps. The mipmaps of each level are included in the set of pre-filtered texture maps.

In a specific embodiment provided in this application, for example, the size of a target map is 512*512 (pixels), and virtual texture processing is performed on it to generate mipmaps of 9 sizes, that is, mipmaps of 9 levels, respectively using m1 -m9 corresponds to 9 mipmaps of different sizes, and the pre-filtered texture map set is (m1, m2, m3, m4, m5, m6, m7, m8, m9), where the size of m1 is 512*512, and the size of m2 is 256*256, m3 size is 128*128, m4 size is 64*64, m5 size is 32*32, m6 size is 16*16, m7 size is 8*8, m8 size is 4* 4. The size of m9 is 2*2.

In the actual reference, the size of the target texture is various, such as 728*67, 128*502, etc. The size of these textures is not a square representation, in order to better perform virtual texture processing on the target texture, for these The non-square texture may also undergo some preprocessing. Specifically, virtual texture processing is performed on the target texture in response to the texture processing instruction, including:

Standardize the target texture to obtain an initial target texture;

Virtual texturing is performed on the initial target map.

Among them, standardizing the target texture refers to converting the target texture into a square size. For example, a target texture with a size of 128*502 can be standardized and converted into an initial target texture with a size of 512*512. The initial target map of 512*512 is used for virtual texture processing.

It should be noted that the pre-filtered texture maps of all sizes in the pre-filtered texture map set in this application include edge expansion processing, and the edge expansion processing of the mipmap can ensure that the mipmap can be more complete during the application process. render.

Step 106: Determine a first pre-filter texture map set in the pre-filter texture map set based on a preset physical page size.

The physical page (Page) is the basic unit for storing the mipmap. After the mipmap is generated, the mipmap needs to be filled into the Page for storage.

In practical applications, the size of the Page is set according to the preset conditions. For example, the size of the Page can be set to 128*128, that is, the preset physical page size is 128*128, and the Page of this size can store the size of 128*128 mipmaps.

Based on the preset physical page size, the first pre-filtered texture map set may be determined in the pre-filtered texture map set, wherein the first pre-filtered texture map in the first pre-filtered texture map set specifically refers to a size smaller than the preset physical page size. Pre-filtered texture maps.

Specifically, determining the first pre-filtering texture mapping set in the pre-filtering texture mapping set based on the preset physical page size includes:

filtering in the set of pre-filtered texture maps based on the preset physical page size;

A pre-filter texture map whose size is smaller than the preset physical page size is determined to be the first pre-filter texture map.

In the embodiment provided in the present application, a mipmap whose size is smaller than the preset physical page size may become the first pre-filtered texture map, and the preset physical page size is compared and filtered with each mipmap in the pre-filtered texture map set, thereby A first set of pre-filtered texture maps can be obtained.

In a specific implementation provided in this application, taking the preset physical page size as 128*128 as an example, the pre-filtered texture map set is (m1, m2, m3, m4, m5, m6, m7, m8, m9), Among them, the size of m1 is 512*512, and the size of m9 is 2*2. Compare the preset physical page size of 128*128 with each mipmap, and determine that the size of m4-m9 is less than 128*128, then the first pre-filtered texture map set is (m4, m5, m6, m7, m8, m9).

In the pre-filtered texture map set, there are not only mipmaps smaller than the preset physical page size, but also a second pre-filtered texture map larger than or equal to the preset physical page size. Specifically, the method further includes:

determining a second set of pre-filtered texture maps in the set of pre-filtered texture maps based on the preset physical page size;

determining a physical page corresponding to each second pre-filter texture map in the second pre-filter texture map set according to the preset physical page size;

Each second pre-filtered texture map is segmented based on the virtual texture configuration, and the segmented result is filled into a physical page corresponding to each of the second pre-filtered texture maps.

Wherein, determining the second pre-filtering texture mapping set in the pre-filtering texture mapping set according to the preset physical page size refers to classifying the mipmaps whose size is greater than or equal to the preset physical page size as the second pre-filtering texture mapping. include:

filtering in the set of pre-filtered texture maps based on the preset physical page size;

It is determined that the pre-filtering texture map whose size is greater than or equal to the preset physical page size is the second pre-filtering texture map.

In the specific implementation provided by this application, following the above example, the preset physical page size is 128*128, and it is determined that the size of m1-m3 is greater than or equal to 128*128, then the second pre-filtered texture mapping set is (m1, m2, m3).

After the second pre-filtering texture map set is determined, each second pre-filtering texture map needs to be segmented and stored. Here, taking m2 as an example, the size of m2 is 256*256, and the preset physical page size is 128*128, then m2 needs to be stored in 4 physical pages. According to the virtual texture configuration information, m2 is divided into 4 blocks of 128*128 size sub-pre-filter texture maps. Labeled as m2-1, m2-2, m2-3 and m2-4 in order from left to right, top to bottom. The size of each sub-pre-filter texture map corresponding to m2 is 128*128. Assign Page1 to m2-1, and fill m2-1 into Page1; assign Page2 to m2-2, and fill m2-2 into Page2; assign Page3 to m2-3, and fill m2-3 into Page3 , assign Page4 to m2-4, and fill m2-4 into Page4.

Step 108: Fill the first pre-filter texture map in the first pre-filter texture map set into the basic physical page according to the preset filling rule, and record each first pre-filter texture map in the basic physical page offset information.

After acquiring the first pre-filtered texture map set, in order to save the first pre-filtered texture map whose size is smaller than the Page size, the first pre-filtered texture map can be saved in the basic physical page, and all the first pre-filtered texture maps saved in the basic physical page The sampling rules of a pre-filtered texture map are compatible with the sampling of other Pages and support all sampling methods.

Specifically, in order to better store the first pre-filter texture map, a preset filling rule may be used to fill the first filter texture map into the basic physical page in the order of size. The preset filling rule may be filling according to a stair path. Referring to FIG. 2 , FIG. 2 shows a schematic diagram of filling a basic physical page provided by an embodiment of the present application. As shown in Figure 2, the size of the Page is 128*128. First, place the 64*64 m4 in the upper left corner of the Page, place the 32*32 m5 in the upper left corner of the right side of the m4, and place the 16*16 m6 in the upper left corner. In the upper left corner below m5, place 8*8 m7 in the upper left corner on the right side of m6, place 4*4 m8 in the upper left corner below m7, and place 2*2 m9 in the upper left corner on the right side of m8 .

Referring to FIG. 3 , FIG. 3 shows a schematic diagram of filling another basic physical page provided by an embodiment of the present application. As shown in Figure 3, the size of the Page is 128*128. First, place the 64*64 m4 in the upper left corner of the Page, place the 32*32 m5 in the upper left corner below the m4, and place the 16*16 m6 in the upper left corner of the page. In the upper left corner of the right side of m5, place 8*8 m7 in the upper left corner below m6, place 4*4 m8 in the upper left corner of the right side of m7, and place 2*2 m9 in the upper left corner below m8.

FIG. 2 and FIG. 3 show two filling modes of the present application. In practical applications, there may also be other regular filling modes, which are subject to practical applications.

After filling each mipmap into the basic physical page, it is also necessary to record the offset information of each mipmap in the basic physical page. Specifically, the offset information records the pixel coordinates of the upper left corner of each mipmap and the coordinates of the upper left corner of the basic physical page. offset information. According to the offset information and size information of each mipmap, the mipmap can be quickly and accurately found in the basic physical page.

Specifically, filling the first pre-filtering texture map in the first pre-filtering texture map set into the basic physical page according to a preset filling rule, including:

S1082. Determine a target first preset filter texture map in the first preset filter texture map set.

Among them, the target first pre-filtering texture map specifically refers to the mipmap currently filling the basic physical page. In practical applications, the filling order is usually determined according to the size of each pre-filtering texture map, and the mipmap with a large size is filled first. , fill after the mipmap with small size.

S1084. Determine target offset information corresponding to the target first preset filter texture map in the basic physical page based on a preset filling rule.

The preset filling rule is the stair path proposed in this application, that is, the adjustment directions of the horizontal and vertical directions are determined, and the position information of each first pre-filtered texture map is determined in the basic physical page in the manner of alternating horizontal and vertical in turn, For example, the first mipmap (64*64) is placed in the upper left corner of the basic physical page, and its offset information is (0, 0), and the second mipmap (32*32) is placed in the upper left corner of the right side of the first mipmap. , then it is offset by 64 in the horizontal direction, and there is no offset in the vertical direction. The offset information of the second mipmap is (64, 0); the third mipmap (16*16) is placed under the second mipmap, and the offset If it is 32, the offset information of the third mipmap is (64, 32) ...... and so on, the target offset information of the target mipmap can be determined.

S1086. Determine, according to the target offset information, a target filling position where the target first preset filter texture is mapped in the basic physical page.

According to the target offset information, the target filling position of the target mipmap in the basic physical page can be determined, that is, starting from (0, 0), the position information that the target mipmap needs to be filled in the basic physical page can be determined according to the target offset information.

For example, the size of the third mipmap is 16*16, and its offset information is (64, 32), then the target filling position of the third mipmap is (64, 32, 16, 16), representing the third mipmap It occupies an area with coordinates (64, 32), 16 pixels horizontally and 16 pixels vertically.

S1088. Fill the target first preset filter texture map to the target filling position.

After the target filling position is determined, the target mipmap can be filled to the target filling position. After all the first preset filter texture maps corresponding to the target map are filled into the basic physical page, the storage of the first preset filter texture maps is completed.

In practical applications, after the mipmap is stored, when the mipmap needs to be adopted, it needs to be sampled according to the Page. In another specific embodiment provided by this application, the method further includes:

receiving a sampling request, wherein the sampling request carries a sampling size;

In the case that the sampling size is smaller than the preset physical page size, determining a target pre-filtering texture map corresponding to the sampling size, and acquiring target offset information corresponding to the target pre-filtering texture mapping;

obtaining the target pre-filter texture map in the base physical page based on the target offset information and the sample size;

A target map sample is generated based on the target pre-filtered texture map and the target map.

In practical applications, it is also necessary to sample the target texture, and the sampling request carries the sampling size. For example, the sampling size of the mipmap to be sampled can be determined according to the distance between the virtual camera and the target object. If the size is smaller than the preset physical page size, it means that the mipmap to be sampled is stored in the basic physical page, the target mipmap corresponding to the sample size is determined, and the target offset information corresponding to the target mipmap is obtained.

After the target offset information is obtained, the target mipmap can be obtained in the basic physical page according to the target offset information and the sample size, and the target texture sample corresponding to the sample size can be generated based on the target mipmap and the target texture.

Specifically, the target offset information includes the offset abscissa and offset ordinate of the target mipmap from the reference position information. For example, for the sample size of the target mipmap is 16*16, the corresponding target offset information is (64, 32) , indicating that the offset information of the target mipmap from the reference position information (0, 0) in the basic physical page is a horizontal offset (x direction) of 64 pixels, and a vertical offset (y direction) of 32 pixels. First, find the target position information (64, 32) of the target mipmap through the target offset information, and then obtain the target mipmap through the sampling size of the target mipmap 16*16. After that, you can combine the target texture to generate a 16*16 size target texture sample.

In another specific implementation manner provided by the present application, after the target texture samples are acquired, rendering may also be performed based on the target texture samples to obtain a rendering result.

In the texture mapping processing method provided by the present application, a texture processing instruction for a target texture is received; virtual texture processing is performed on the target texture in response to the texture processing instruction, and a pre-filtered texture mapping set corresponding to the target texture is obtained, wherein, The pre-filter texture map set includes pre-filter texture maps of multiple sizes; a first pre-filter texture map set is determined in the pre-filter texture map set based on a preset physical page size; the pre-filter texture map set is determined according to a preset filling rule. The first pre-filter texture maps in the first pre-filter texture map set are filled into the basic physical page, and the offset information of each first pre-filter texture map in the basic physical page is recorded.

An embodiment of the present application realizes that the pre-filtered texture map whose size is smaller than the size of the physical page is filled into the basic physical page for storage, and the offset of each pre-filtered texture map stored in the basic physical page is recorded in the basic physical page. The information is used for subsequent restoration based on the pre-filtered texture map stored in the basic physical page, which solves the problem of the lack of pre-filtered texture maps whose size is smaller than the physical page, and completes the pre-filtered texture corresponding to all resolutions corresponding to the target map. map.

The following will further describe the texture mapping processing method by taking the application of the texture mapping processing method provided by the present application to game textures in a game scene as an example with reference to FIG. 4 . 4 shows a processing flowchart of a texture mapping processing method applied to a game texture in a game scene provided by an embodiment of the present application, which specifically includes the following steps:

Step 402: Acquire a target game texture, and receive a texture processing instruction for the target game texture.

Step 404 : perform normalization processing on the target game texture in response to the texture processing instruction to obtain an initial target game texture.

Step 406: Perform virtual texture processing on the initial target game texture to obtain a multi-size mipmap chain corresponding to the target game texture.

Step 408: Determine the mipmap whose size is smaller than the preset Page size as the first mipmap, and determine the mipmap whose size is greater than or equal to the preset Page size as the second mipmap.

Step 410: Segment each second mipmap based on the virtual texture configuration, and fill the segmented result into the corresponding Page page.

Step 412: Determine the offset information of each first mipmap in the basic physical page;

Step 414: Determine the filling position of each first mipmap according to the offset information corresponding to each first mipmap.
