Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a texture mapping processing method, a texture mapping processing device, a computing device, and a computer-readable storage medium. Background Art

[0002] With the development of computer technology, scene construction in virtual scenes is a development branch of computer technology. Virtual Texture (VT) is a texture technology solution that allows real-time large-volume rendering of texture data and places the entire texture data into video memory for continuous sampling through virtual mapping. In practical applications, it is also called virtual mapping technology.

[0003] Mipmap is one of the most widely used texture mapping technologies. In order to speed up rendering and reduce image aliasing, the texture will be processed into a series of pre-calculated and optimized pre-filtered texture mappings. Such pre-filtered texture mapping is called Mipmap. There is a problem with virtual texture technology based on software implementation, which is that the missing Mipmap size is smaller than the physical page, which will cause the texture material of the missing size to be distorted during real-time rendering, resulting in snowflakes flickering in the corresponding part of the picture and unstable picture.

[0039] It should be understood that, although the terms first, second, etc. may be used to describe various information in one or more embodiments of the present application, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other.

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

[0040] First, the terms involved in one or more embodiments of the present application are explained.

[0041] Virtual texture (VT): is a texture technology solution that allows real-time large-volume rendering of texture data and places the entire texture data into video memory for continuous sampling through virtual mapping.

[0042] Pre-filtered texture map (Mipmap): It is a smaller version of the texture image that is pre-filtered. It represents the different levels of detail (LOD) of the texture and is usually stored in a series of shrinking texture objects. These textures are called mipmap chains, and each level is half the size of the previous level.

[0043] In the present application, a texture mapping processing method is provided. The present application also relates to a texture mapping processing device, a computing device, and a computer-readable storage medium, which are described in detail one by one in the following embodiments.

[0044] Figure 1 A flowchart of a texture mapping processing method provided according to an embodiment of the present application is shown, which specifically includes the following steps:

[0045] Step 102: Receive a texture processing instruction for a target texture.

[0046] In the process of virtual scene production, we will encounter the situation of mapping three-dimensional models and generating corresponding virtual scenes. Virtual scenes include but are not limited to game scenes, animation scenes, movie special effects scenes, VR scenes, etc.

[0047] In virtual scenes, it is common to encounter situations where the virtual lens is zoomed in or out. For example, for the same object, the details of the object are different when the virtual lens is at different distances from the object. When the virtual lens is closer to the object, more details of the object need to be presented. When the virtual lens is farther away from the object, the object may only appear as a black dot. Due to the difference in the distance between the virtual lens and the object, texture filtering will be applied. Therefore, the texture is rendered at different resolutions depending on the distance from the virtual lens.

[0048] Based on this, it is necessary to create a multi-resolution (multi-size) pre-filtered texture map (mipmap) for the map. Mipmap is currently the most effective way to solve the relationship between texture resolution and viewpoint distance. In the method provided by the present application, the map processing instruction specifically refers to an instruction to generate a multi-resolution mipmap for the map, and the target map is the map for which a multi-size pre-filtered texture map needs to be generated.

[0049] In a specific implementation provided in the present application, taking the target texture as texture P as an example, a texture processing instruction for texture P is received, and the texture processing instruction is used to generate multi-size mipmaps of texture P.

[0050] Step 104: In response to the texture processing instruction, virtual texture processing is performed on the target texture to obtain a pre-filtered texture mapping set corresponding to the target texture.

[0051] The pre-filtered texture mapping set includes pre-filtered texture mappings of various sizes.

[0052] Virtual texture (VT) is a texture technology solution that allows real-time large-volume rendering of texture data and places the entire texture data into the video memory for continuous sampling through virtual mapping. By processing the target map with virtual texture, a series of pre-filtered texture mappings can be generated from the target map and stored in corresponding texture objects of continuously reduced sizes to obtain a pre-filtered texture mapping set corresponding to the target map. The pre-filtered texture mapping set can also be called a mipmap chain. The pre-filtered texture mapping set includes mipmaps of each level.

[0053] In a specific implementation provided in the present application, for example, the size of a target map is 512*512 (pixels). By performing virtual texture processing on it, mipmaps of 9 sizes can be generated, that is, 9 levels of mipmaps, and m1-m9 correspond to 9 mipmaps of different sizes respectively. The pre-filtered texture mapping set is (m1, m2, m3, m4, m5, m6, m7, m8, m9), where the size of m1 is 512*512, the size of m2 is 256*256, the size of m3 is 128*128, the size of m4 is 64*64, the size of m5 is 32*32, the size of m6 is 16*16, the size of m7 is 8*8, the size of m8 is 4*4, and the size of m9 is 2*2.

[0054] In actual reference, the size of the target map is various, such as 728*67, 128*502, etc. The sizes of these maps are not square representations. In order to better perform virtual texture processing on the target map, some preprocessing can be performed on these non-square maps. Specifically, in response to the map processing instruction, the virtual texture processing is performed on the target map, including:

[0055] Performing standardization processing on the target map to obtain an initial target map;

[0056] Virtual texturing is performed on the initial target map.

[0057] Among them, standardizing the target map means converting the target map into a square size. For example, a target map with a size of 128*502 can be standardized and converted into an initial target map with a size of 512*512, and then the initial target map with a size of 512*512 can be virtual textured.

[0058] It should be noted that all sizes of pre-filtered texture maps in the pre-filtered texture map set in the present application include edge expansion processing. Expanding the mipmap can ensure that the mipmap can be presented more completely during the application process.

[0059] Step 106: Determine a first pre-filtered texture mapping set in the pre-filtered texture mapping set based on a preset physical page size.

[0060] The physical page is the basic unit for storing mipmap. After the mipmap is generated, the mipmap needs to be filled into the Page for storage.

[0061] In actual applications, the size of the Page is set according to 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 a Page of this size can store a mipmap of 128*128 size.

[0062] A first pre-filtered texture mapping set may be determined in the pre-filtered texture mapping set based on a preset physical page size, wherein the first pre-filtered texture mapping in the first pre-filtered texture mapping set specifically refers to a pre-filtered texture mapping having a size smaller than the preset physical page size.

[0063] Specifically, determining a first pre-filtered texture mapping set in the pre-filtered texture mapping set based on a preset physical page size includes:

[0064] Filtering the pre-filtered texture map set based on the preset physical page size;

[0065] A pre-filtered texture map having a size smaller than the preset physical page size is determined as a first pre-filtered texture map.

[0066] In the embodiment provided in the present application, a mipmap whose size is smaller than a preset physical page size can become a first pre-filtered texture mapping, and the preset physical page size is compared and screened with each mipmap in a pre-filtered texture mapping set, so as to obtain a first pre-filtered texture mapping set.

[0067] In a specific implementation provided by the present application, taking the preset physical page size of 128*128 as an example, the pre-filtered texture mapping set is (m1, m2, m3, m4, m5, m6, m7, m8, m9), wherein the size of m1 is 512*512, ... the size of m9 is 2*2. The preset physical page size of 128*128 is compared with each mipmap respectively, and it is determined that the size of m4-m9 is less than 128*128, then the first pre-filtered texture mapping set is (m4, m5, m6, m7, m8, m9).

[0068] The pre-filtered texture mapping set not only has mipmaps smaller than the preset physical page size, but also has a second pre-filtered texture mapping greater than or equal to the preset physical page size. Specifically, the method further includes:

[0069] determining a second pre-filtered texture map set in the pre-filtered texture map set based on the preset physical page size;

[0070] Determining a physical page corresponding to each second pre-filtered texture mapping in the second pre-filtered texture mapping set according to the preset physical page size;

[0071] 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 second pre-filtered texture map.

[0072] Wherein, determining the second pre-filtering texture mapping set in the pre-filtering texture mapping set according to the preset physical page size means classifying the mipmaps whose size is greater than or equal to the preset physical page size as the second pre-filtering texture mapping.

[0073] Filtering the pre-filtered texture map set based on the preset physical page size;

[0074] A pre-filtered texture map having a size greater than or equal to the preset physical page size is determined as a second pre-filtered texture map.

[0075] In the specific implementation provided in the present application, following the above example, the preset physical page size is 128*128, and the size of m1-m3 is determined to be greater than or equal to 128*128, then the second pre-filtered texture mapping set is (m1, m2, m3).

[0076] After determining the second pre-filtered texture mapping set, each second pre-filtered texture mapping 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 segmented into 4 128*128 sub-pre-filtered texture mappings. They are marked as m2-1, m2-2, m2-3 and m2-4 from left to right and from top to bottom. The size of each sub-pre-filtered texture mapping corresponding to m2 is 128*128. Page1 is allocated to m2-1, and m2-1 is filled into Page1; Page2 is allocated to m2-2, and m2-2 is filled into Page2; Page3 is allocated to m2-3, and m2-3 is filled into Page3; Page4 is allocated to m2-4, and m2-4 is filled into Page4.

[0077] Step 108: fill the first pre-filtered texture mappings in the first pre-filtered texture mapping set into the basic physical page according to a preset filling rule, and record the offset information of each first pre-filtered texture mapping in the basic physical page.

[0078] After obtaining the first pre-filtered texture mapping set, in order to save the first pre-filtered texture mapping whose size is smaller than the Page size, the first pre-filtered texture mapping can be saved in the basic physical page. All sampling rules of the first pre-filtered texture mapping saved in the basic physical page are compatible with the sampling of other Pages and support all sampling methods.

[0079] Specifically, in order to better store the first pre-filtered texture map, the first filtered texture map may be filled into the basic physical page in the order of size using a preset filling rule. The preset filling rule may be to fill in according to the stair path, see Figure 2 , Figure 2 FIG. 2 shows a schematic diagram of filling a basic physical page provided by an embodiment of the present application. Figure 2 As shown, the size of Page is 128*128. First, place 64*64 m4 in the upper left corner of Page, place 32*32 m5 in the upper left corner to the right of m4, place 16*16 m6 in the upper left corner below m5, place 8*8 m7 in the upper left corner to the right of m6, place 4*4 m8 in the upper left corner below m7, and place 2*2 m9 in the upper left corner to the right of m8.

[0080] See also Figure 3 , Figure 3 FIG. 2 shows a schematic diagram of filling another basic physical page provided by an embodiment of the present application. Figure 3As shown, the size of Page is 128*128. First, place 64*64 m4 in the upper left corner of Page, place 32*32 m5 in the upper left corner below m4, place 16*16 m6 in the upper left corner to the right of m5, place 8*8 m7 in the upper left corner below m6, place 4*4 m8 in the upper left corner to the right of m7, and place 2*2 m9 in the upper left corner below m8.

[0081] Figure 2 and Figure 3 Two filling methods of the present application are shown. In actual applications, there may be other regular filling methods, which shall be subject to actual applications.

[0082] After each mipmap is filled into the base physical page, the offset information of each mipmap in the base physical page needs to be recorded. Specifically, the offset information records the offset information between the upper left pixel coordinates of each mipmap and the upper left pixel coordinates of the base physical page. Based on the offset information and size information of each mipmap, the mipmap can be found in the base physical page quickly and accurately.

[0083] Specifically, filling the first pre-filtered texture mapping in the first pre-filtered texture mapping set into the basic physical page according to a preset filling rule includes:

[0084] S1082. Determine a target first preset filter texture mapping in the first preset filter texture mapping set.

[0085] The target first pre-filtered texture map specifically refers to the mipmap currently being filled into the base physical page. In practical applications, the filling order is usually determined according to the size of each pre-filtered texture map, with the larger mipmap being filled first and the smaller mipmap being filled later.

[0086] S1084. Determine, in the basic physical page, target offset information corresponding to the target first preset filtering texture mapping based on a preset filling rule.

[0087] The preset filling rule is the stair path proposed in the present application, that is, determining the horizontal and vertical adjustment directions, and determining the position information of each first pre-filtered texture mapping in the basic physical page in an alternating horizontal and vertical manner. 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). The second mipmap (32*32) is placed in the upper left corner on the right side of the first mipmap. It is offset by 64 horizontally and has no vertical offset. The offset information of the second mipmap is (64, 0); the third mipmap (16*16) is placed below the second mipmap, with an offset of 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.

[0088] S1086. Determine a target filling position of the target first preset filtering texture mapping in the basic physical page according to the target offset information.

[0089] The target filling position of the target mipmap in the basic physical page can be determined according to the target offset information, that is, starting from (0, 0), the position information where the target mipmap needs to be filled in the basic physical page can be determined according to the target offset information.

[0090] For example, the size of the third mipmap is 16*16, and its offset information is (64, 32). Then the target fill position of the third mipmap is (64, 32, 16, 16), which means that the third mipmap occupies the area with coordinates (64, 32), 16 pixels horizontally and 16 pixels vertically.

[0091] S1088. Fill the target first preset filtered texture mapping to the target filling position.

[0092] After the target filling position is determined, the target mipmap can be filled to the target filling position. After the first preset filter texture map corresponding to the target map is completely filled into the basic physical page, the storage of the first preset filter texture map is completed.

[0093] In practical applications, after the mipmap is stored, when the mipmap needs to be adopted, it is also necessary to sample according to the Page. In another specific implementation provided by the present application, the method further includes:

[0094] receiving a sampling request, wherein the sampling request carries a sampling size;

[0095] In a case where the sampling size is smaller than the preset physical page size, determining a target pre-filtering texture mapping corresponding to the sampling size, and acquiring target offset information corresponding to the target pre-filtering texture mapping;

[0096] Retrieve the target pre-filtered texture map in the base physical page based on the target offset information and the sampling size;

[0097] Target map samples are generated based on the target pre-filtered texture map and the target map.

[0098] In practical applications, it is also necessary to sample the target map. Specifically, the sampling size is carried in the sampling request. For example, the sampling size of the mipmap to be sampled can be determined based on the distance between the virtual camera and the target object. When the sampling size of the mipmap 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 sampling size is determined, and the target offset information corresponding to the target mipmap is obtained.

[0099] 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 sampling size, and the target map sample corresponding to the sampling size can be generated based on the target mipmap and the target map.

[0100] Specifically, the target offset information includes the horizontal coordinate and vertical coordinate of the target mipmap's offset from the reference position information. For example, if the sampling 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 base physical page is 64 pixels horizontally (in the x direction) and 32 pixels vertically (in the y direction). 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, which is 16*16. Then, combine the target map to generate a target map sample of 16*16 size.

[0101] In another specific implementation provided in the present application, after obtaining the target map sampling, rendering may be performed based on the target map sampling to obtain a rendering result.

[0102] The texture mapping processing method provided in the present application receives a texture processing instruction for a target map; performs virtual texture processing on the target map in response to the texture processing instruction to obtain a pre-filtered texture mapping set corresponding to the target map, wherein the pre-filtered texture mapping set includes pre-filtered texture mappings of multiple sizes; determines a first pre-filtered texture mapping set in the pre-filtered texture mapping set based on a preset physical page size; fills the first pre-filtered texture mapping in the first pre-filtered texture mapping set into a basic physical page according to a preset filling rule, and records the offset information of each first pre-filtered texture mapping in the basic physical page.

[0103] An embodiment of the present application implements the storage of pre-filtered texture mappings whose sizes are smaller than the physical page size into the base physical page, and records the offset information of each pre-filtered texture mapping stored in the base physical page in the base physical page, which is used for subsequent restoration based on the pre-filtered texture mapping stored in the base physical page, thereby solving the problem of lack of pre-filtered texture mappings whose sizes are smaller than the physical page, and completing the pre-filtered texture mappings corresponding to all resolutions corresponding to the target map.

[0104] The following combination Figure 4 , taking the application of the texture mapping processing method provided by the present application to the game map in the game scene as an example, the texture mapping processing method is further described. Figure 4 A processing flow chart of a texture mapping processing method for a game map in a game scene provided by an embodiment of the present application is shown, which specifically includes the following steps:

[0105] Step 402: Obtain a target game texture, and receive a texture processing instruction for the target game texture.

[0106] Step 404: In response to the texture processing instruction, the target game texture is standardized to obtain an initial target game texture.

[0107] 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.

[0108] Step 408: determine a mipmap whose size is smaller than the preset Page size as the first mipmap, and determine a mipmap whose size is greater than or equal to the preset Page size as the second mipmap.

[0109] Step 410: Divide each second mipmap based on the virtual texture configuration, and fill the division result into the corresponding Page page.

[0110] Step 412: Determine the offset information of each first mipmap in the base physical page;

[0111] Step 414: Determine the filling position of each first mipmap according to the offset information corresponding to each first mipmap.

[0112] Step 416: Fill each first mipmap to the corresponding filling position, and save the offset information of each first mipmap.
