[0070] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0071] Embodiments of the present invention provide a data processing method, device, electronic device and storage medium.

[0072] The data processing device may be integrated in an electronic device, which may be a terminal, a server, etc. The terminal may be a mobile phone, a tablet computer, a smart Bluetooth device, a laptop computer, or a personal computer (PC).

[0073] In some embodiments, the data processing device may also be integrated into multiple electronic devices, for example, the data processing device may be integrated into a terminal device and a server, and the terminal device and the server jointly implement the data processing method of the present invention. The server may be a single server or a server cluster composed of multiple servers.

[0074] For example, refer to Figure 1a , Figure 1a Schematic diagram of a scenario of a data processing method provided by an embodiment of the present invention. The scenario of the data processing method may include a terminal device and a server. Figure 1a In the embodiment, the terminal device can obtain multiple baking objects, which are objects used to store lighting information in a three-dimensional space. The terminal device integrates the multiple baking objects to obtain an integrated baking object. The terminal device generates a baking instruction for the integrated baking object. The terminal device sends the baking instruction and the integrated baking object to a server, which is equipped with a graphics processor, so that the server uses the graphics processor to bake the integrated baking object into an integrated lighting map based on the baking instruction; the terminal device receives the integrated lighting map from the server. The terminal device splits the integrated lighting map to obtain a lighting map corresponding to each baking object.

[0075] In the embodiment of the present invention, the terminal device integrates multiple baking objects into one baking object, and the graphics processor then bakes the integrated baking object; baking the integrated baking object requires more computing units to process, which can make full use of the computing units of the graphics processor, and try to make the graphics processor run at full capacity, avoiding the computing units being idle and wasted. Therefore, this solution can improve the efficiency of baking.

[0076] It should be noted that the serial numbers of the following embodiments are not intended to limit the preferred order of the embodiments.

[0077] In this embodiment, a data processing method based on data processing is provided, such as Figure 1b As shown, the specific process of the data processing method can be as follows:

[0078] 101. Get multiple baking objects.

[0079] Among them, the baking object is an object used to store lighting information in a three-dimensional space. The object may include but is not limited to the texture map and lighting samples of the model; the basic models such as characters, scenes and buildings in the three-dimensional space are all implemented based on the three-dimensional stereo model; the lighting information may include information about the light irradiating the model surface, information about the light penetration between models, and information about the light passing through the blank space in the scene. It should be noted that in the embodiment of the present invention, multiple refers to two or more, that is, multiple baking objects refer to two or more baking objects.

[0080] In some embodiments, the object storing the illumination information is a texture map of a model. The model may be a basic model such as a person, scene, or building in a three-dimensional space. Figure 1c , which is a schematic diagram of a texture map of a model provided by an embodiment of the present invention, Figure 1c (I) in the figure is used to represent the texture map of a cone when the model is a cone; Figure 1c (ii) is used to represent the texture map of a ball when the model is a ball. The implementation method of the terminal device obtaining the texture map of the model is not limited; optionally, the texture map of the role model can be customized according to the actual application situation, for example, the texture map of the role model can be customized according to the role requirements of the established role model.

[0081] In some embodiments, the object storing the illumination information is an illumination sample, which is the spatial position of a plurality of illumination information sampling points in a three-dimensional space. Figure 1d FIG. 1 is a schematic diagram showing the distribution of illumination information sampling points provided by an embodiment of the present invention. Figure 1d Each sphere 100 represents a lighting information sampling point, and the lighting conditions on the spherical surface of the sphere can be used to represent the changes in lighting information. The lighting samples can be the spatial positions corresponding to 4×4×4 lighting information sampling points. The specific implementation method for the terminal device to obtain the lighting samples is not limited; for example, the terminal device can obtain a bounding box specified by the user, divide the bounding box into multiple blocks according to the user configuration, and subdivide each block into one to thousands of units (Bricks) formed by 4×4×4 lighting information sampling points according to the different scene complexities of the position of each block in the three-dimensional space, thereby obtaining lighting samples.

[0082] 102. Integrate multiple baking objects to obtain an integrated baking object.

[0083] Among them, the integrated baking object may include but is not limited to integrated texture maps and integrated lighting samples; the integrated baking object is a representation form after multiple baking objects are integrated, for example, the integrated texture map is a representation form after the texture maps of multiple models are integrated, and the integrated lighting sample is a representation form after multiple lighting samples are integrated.

[0084] In some embodiments, the object storing the illumination information is a texture map of a model, and the integrated baking object is an integrated texture map; the terminal device integrates the texture maps of multiple models to obtain a specific implementation of the integrated texture map, which may include but is not limited to the following steps:

[0085] (i) Obtaining a preset image size and an image size of a texture map.

[0086] The preset image size is the image size of the integrated texture map. Optionally, the image size can be customized according to actual application conditions, for example, according to a graphics processing unit (GPU) used to bake the integrated texture map.

[0087] The terminal device obtains the image size of the texture map, which can be determined by the corresponding model. It should be noted that texture maps are generally square, and most of them use several specific image sizes. Different image sizes are usually in multiples. For example, the image sizes of common texture maps are 8×8, 16×16, 32×32, 64×64, 128×128 pixels, etc.

[0088] Optionally, before obtaining the preset image size, the terminal device determines the preset image size according to the number of threads of the graphics processor. Taking a graphics processor with 72 computing units (Streaming Multiprocessor, SM) as an example, each computing unit can be resident (Resident) at most 2048 threads at the same time, so the number of fully loaded threads that the graphics processor can support is 72×2048=147456. Since texture images are generally square, and generally one thread can process one pixel, 147456=384×384, that is, images with a size of 384×384 pixels or more can make the graphics processor run at full load; therefore, the preset image size can be 256×256, 512×512 and 1024×1024.

[0089] (ii) sorting the texture maps according to their image sizes to obtain a sorted texture map group.

[0090] The sorted texture map group includes a plurality of ordered texture maps. Optionally, the texture maps are sorted from large to small according to their image size to obtain the sorted texture map group; the texture maps can also be sorted from small to large according to their image size to obtain the sorted texture map group; this is not limited in the embodiment of the present invention.

[0091] (iii) Integrating the texture images in the sorted texture image group according to a preset image size to obtain an integrated texture image.

[0092] There is no limitation on the specific implementation method of integrating the texture images in the sorted texture image group according to the preset image size, and may include but is not limited to the following implementation methods.

[0093] In one implementation, when there is a texture map in the sorted texture map group, the terminal device generates a blank map of a preset image size; the terminal device inserts the texture map in the sorted texture map group into the blank map to obtain an integrated texture map. When there is no texture map in the sorted texture map group, the integration process of the texture maps in the sorted texture map group ends.

[0094] The blank map can be a blank image, i.e., an image with image size but empty pixel values, where the pixel values ​​include the position and color value of each pixel. The blank map is used to make the integrated texture map a regular image when integrating multiple texture maps, for example, a square image.

[0095] It should be noted that, since there are multiple texture maps in the sorted texture map group, and the image size of the blank map is fixed; therefore, when there are texture maps in the sorted texture map group, the texture map integration process is an iterative process, and multiple integrated texture maps will be obtained in the end. Here, only the texture map integration process is used as an example to illustrate.

[0096] ⑴The terminal device generates a blank map of a preset image size.

[0097] It should be noted that each time a blank map is generated, the terminal device may determine the first texture map in the sorted texture map group as the current texture map.

[0098] (2) The terminal device obtains the current texture map. The current texture map is used to indicate the texture map in the sorted texture map group that is about to be inserted with a blank map; for example, the current texture map and other texture maps to be inserted can be distinguished by marking the texture map. Generally, there is only one current texture map in the sorted texture map group.

[0099] ⑶ The terminal device inserts the current texture image into the blank map. The terminal device inserts the current texture image into the blank map according to the preset image size and the rule that the texture images are closely connected; for example, see Figure 1e , is a schematic diagram of a texture image in a blank map provided by an embodiment of the present invention. Figure 1eAs shown in the figure, when inserting the first texture image S1 into the blank map, S1 can be inserted into the upper left corner of the blank map, and its boundary coincides with the boundary of the blank map; when inserting the second texture image S2, the left boundary of S2 coincides with the right boundary of S1, and so on. When inserting a texture image in the first row will exceed the boundary of the blank map, a new row is started to continue inserting the texture image.

[0100] (4) When the current texture image is successfully inserted into the blank map, the insertion success processing is executed.

[0101] When the current texture map is successfully inserted into the blank map, the terminal device deletes the current texture map from the sorted texture map group; then determines that the texture map of the next texture map in the sorted texture map group is the current texture map; and obtains the next texture map, inserts the texture map into the blank map, and returns to execute step (2), thereby forming a loop. It should be noted that when the terminal device cannot obtain the next texture map, it determines whether there are still texture maps in the sorted texture map group. When there are texture maps in the sorted texture map group, the terminal device generates a blank map of a preset image size and enters the next integration process. When there are no texture maps in the sorted texture map group, the integration process ends.

[0102] ⑸ When the current texture image fails to be inserted into the blank map, execute the insertion failure processing.

[0103] Among them, failure to insert the current texture map into the blank map is used to indicate that inserting the current texture map into the blank map will exceed the boundary of the blank map, so the current map is not inserted into the blank map; the current map is still in the sorted texture map group and can wait for the next integration process to be inserted into the blank map generated by the next integration process.

[0104] The specific implementation methods of insert failure processing are not limited, and include but are not limited to the following methods.

[0105] Method 1: When the current texture fails to be inserted into the blank map, the next texture in the sorted texture group is determined.

[0106] When there is a next texture map in the sorted texture map group, the next texture map in the sorted texture map group is determined to be the current texture map, and the step of obtaining the current texture map is returned to be executed. For example, the next texture map is marked as the current texture map, and the terminal device obtains the next texture map and inserts the texture map into the blank map, that is, returns to execute step (2), thereby forming a loop.

[0107] When there is no next texture map in the sorted texture map group, the process returns to the step of generating a blank map of a preset image size when there is a texture map in the sorted texture map group, that is, entering the next integration process.

[0108] In summary, when the current texture fails to be inserted into the blank map, the terminal device can obtain textures with a smaller image size than the current texture from the sorted textures in descending order of image size, and determine whether they can be inserted into the blank map until there is no texture with a smaller image size in the sorted texture group. Therefore, the number of textures inserted into the blank map can be as large as possible, that is, the same number of textures can generate the least integrated textures.

[0109] Method 2: Before determining the next texture map in the sorted texture map group, the texture space utilization rate can also be determined according to the preset image size and the image size of the texture map in the blank map. The texture map in the blank map is used to indicate the texture map that is successfully inserted into the blank map, and the texture space utilization rate is used to indicate the ratio of the image size of the texture map in the blank map to the preset image size.

[0110] For example, suppose there are n texture images S1, S2, ... Sn in the blank map, and their image sizes are D1×D1, D2×D2, ..., D n ×D n , the texture space utilization can be obtained by the following formula:

[0111]

[0112] Among them, E p Indicates the texture space utilization rate; D i represents the image size of the i-th texture image; D p ×D p Image size representing a blank texture.

[0113] When the texture space utilization is greater than the utilization threshold, the process returns to the step of generating a blank texture of a preset image size when there is a texture in the sorted texture group; when the texture space utilization is not greater than the utilization threshold, the insertion failure processing described in method 1 is performed. The utilization threshold can be customized according to the actual application, for example, it is set to 0.9; that is, when the texture space utilization is greater than 0.9, the next integration process is performed, and when the texture space utilization is not greater than 0.9, the insertion failure processing described in method 1 is performed.

[0114] In summary, when the current texture fails to be inserted into the blank texture, the terminal device first determines the texture space utilization. When the texture space utilization is greater than the utilization threshold, it enters the next integration process. Otherwise, it obtains the texture from the sorted texture map in descending order according to the image size, and determines whether it can be inserted into the blank texture. Therefore, the integration process can be performed without taking too long while ensuring a good texture space utilization.

[0115] Method 3: when the current texture fails to be inserted into the blank map, the process returns to the step of generating a blank map of a preset image size when there is a texture in the sorted texture group; that is, when the current texture fails to be inserted into the blank map, the process directly proceeds to the next integration process. Therefore, the time consumed by the integration process can be minimized.

[0116] In one implementation, the terminal device may also splice the texture maps in the sorted texture map group, and limit the image size of the spliced ​​texture map to be no larger than the preset image size. The spliced ​​texture map is inserted into the blank map to form a regular integrated texture map. Therefore, multiple texture maps can be spliced ​​into a large integrated texture map, which is convenient for subsequent baking of the integrated texture map.

[0117] Optionally, during the integration process, the texture space utilization rate when each integrated texture map is obtained may be recorded, and the texture space utilization rate may be used as one of the evaluation criteria for the integration process.

[0118] In some embodiments, the object storing illumination information is an illumination sample, and the illumination sample is the spatial position of multiple illumination information sampling points in three-dimensional space, and the integrated baking object is an integrated illumination sample; the multiple illumination samples are integrated and processed to obtain the specific implementation method of the integrated illumination sample, and the terminal device linearly arranges the multiple illumination samples into a group to obtain an integrated illumination sample. Among them, multiple illumination samples refer to two or more illumination samples, and the number of illumination samples is obtained according to the number of illumination information sampling points in the bounding box specified by the user. For example, the distribution of illumination information sampling points in three-dimensional space can be regarded as a tree-like distribution. In this embodiment, according to the common illumination information sampling points between illumination samples, the distribution of the tree-like illumination information sampling points is arranged into a linear distribution to obtain an integrated illumination sample.

[0119] 103. Generate baking instructions for the integrated baking object.

[0120] The baking instruction is used to call the graphics processor to bake the integrated baking object. The integrated baking object can refer to the integrated baking object described in step 102 above, and can include but is not limited to integrated texture maps and integrated lighting samples, which will not be repeated here.

[0121] 104. Based on the baking instructions for the integrated baking object, bake the integrated baking object into an integrated light map.

[0122] Among them, baking is the pre-calculation process of global illumination (GI), which shows the combined effect of direct and indirect lighting.

[0123] The integrated light map may include but is not limited to an integrated two-dimensional light map and an integrated volumetric light map. The integrated two-dimensional light map is a two-dimensional light map obtained by baking an integrated texture map, and the integrated two-dimensional light map stores the lighting information of multiple models; the integrated volumetric light map is a volumetric light map obtained by baking an integrated lighting sample, and the integrated volumetric light map stores the lighting information of multiple lighting samples.

[0124] In some embodiments, the terminal device sends a baking instruction and an integrated baking object to a server, and the server is equipped with a graphics processor, so that the server uses the graphics processor to bake the integrated baking object into an integrated lighting map based on the baking instruction; the terminal device receives the integrated lighting map from the server. For example, the terminal device sends an integrated texture map and a baking instruction for the integrated texture map to the server, and the server uses the graphics processor to bake the integrated texture map into an integrated two-dimensional lighting map based on the baking instruction; or the terminal device sends an integrated lighting sample and a baking instruction for the integrated lighting sample to the server, and the server uses the graphics processor to bake the integrated lighting sample into an integrated volumetric lighting map based on the baking instruction.

[0125] In some embodiments, if the terminal device is equipped with a graphics processor, the graphics processor of the terminal device may also be used to bake the integrated baking object into an integrated lighting map, which is not limited in the embodiments of the present invention. For example, the terminal device uses the graphics processor to bake the integrated texture map into an integrated two-dimensional lighting map based on the baking instruction; or the terminal device uses the graphics processor to bake the integrated lighting sample into an integrated volumetric lighting map based on the baking instruction.

[0126] Therefore, in the process of the graphics processor baking the integrated texture map or the integrated lighting samples, the number of times the graphics processor is called can be reduced because multiple texture maps are integrated into a large texture map, and multiple lighting samples are integrated into a large lighting sample before baking; and each baking process of the graphics processor requires more computing cores to process the integrated texture maps and lighting samples, so that the graphics processor makes full use of the computing units of the graphics processor, to a certain extent avoids the situation where some computing units are wasted due to being in an idle state, and improves the baking efficiency.

[0127] 105. Split the integrated illumination map to obtain the illumination map corresponding to each baked object.

[0128] Among them, the light map may include but is not limited to a two-dimensional light map (Light Map) and a volumetric light map (Volumetric Light Map). The two-dimensional light map may be a texture map that stores lighting information and can be applied to the surface of the model; the texture map is a map represented by the arrangement of texels, and the texel is a texture element; the lighting information is information about the light irradiating the surface of the model in the scene and the information about the light penetration between models, that is, the lighting information baked at each position on the surface of the model is stored in the corresponding texel in the two-dimensional light map. The volumetric light map may be a light probe (Light Probe) distributed in a three-dimensional space. A light probe represents a lighting sample at a spatial position in a three-dimensional space, and the lighting information baked by the light sample is stored in the light probe. The light probe can store information about the blank space in the three-dimensional scene where light passes.

[0129] When integrating multiple baking objects, the terminal device can determine the position of the baking object in the integrated baking object, and then store the mapping relationship between the baking object and the position of the baking object in the integrated baking object. After the terminal device obtains the illumination map, it can split the integrated illumination map according to the mapping relationship between the baking object and the position of the baking object in the integrated baking object to obtain the illumination map corresponding to the baking object.

[0130] For example, each model's texture map has a corresponding identifier. After determining the position of the texture map in the integrated texture map, a mapping relationship between the texture map identifier and the texture map's position in the integrated texture map is established, and the mapping relationship is stored in a table. For example, the mapping relationship can be stored in a storage medium such as a cache or memory of a terminal device. When the terminal device obtains the illumination map, since the baking process does not change the position of the texture map, the terminal device can obtain the mapping relationship, and according to the position of the texture map in the integrated texture map and the texture map identifier in the mapping relationship, the illumination map corresponding to each texture map is split from the integrated illumination map to obtain the illumination map corresponding to each texture map.

[0131] The embodiment of the present invention can obtain multiple baking objects, which are objects used to store lighting information; integrate the multiple baking objects to obtain an integrated baking object; generate baking instructions for the integrated baking object; based on the baking instructions for the integrated baking object, bake the integrated baking object into an integrated lighting map; split the integrated lighting map to obtain a lighting map corresponding to each baking object.

[0132] From the above, it can be seen that since the texture maps of multiple models can be integrated into a large texture map, and then the integrated texture map is baked to obtain a lighting map that stores the lighting information of multiple models; then the lighting map is split to obtain the lighting map corresponding to each model; therefore, the graphics processor can bake the texture maps of multiple models at one time; similarly, the lighting samples in the three-dimensional space can be linearly arranged and the arranged lighting samples can be baked, so the graphics processor can bake multiple lighting samples at one time; from the above, when the graphics processor bakes multiple texture maps or multiple lighting samples at one time, more computing units are required for processing, so the computing units of the graphics processor can be fully utilized to avoid the waste caused by the computing units being in an idle state, so that this solution can improve the baking efficiency.

[0133] The data processing solution provided by the embodiment of the present invention can be applied to various lighting baking scenes in three-dimensional space. For example, take the lighting baking scene of a three-dimensional game as an example; in this scene, the baking object can be the texture map of the three-dimensional model in the game, such as the texture map of the game character, props, building and other models; the baking object can also be the lighting sample in the game scene, such as the spatial position of multiple lighting information sampling points in the three-dimensional space of the game scene.

[0134] According to the above Figure 1b The method described in the embodiment will be further described in detail below with respect to the lighting baking scene of a three-dimensional game.

[0135] In this embodiment, the terminal device is installed with a game engine, and the graphics processor has 72 computing units.

[0136] like Figure 2a As shown, when the baking object is a texture map of a three-dimensional model in a game, a specific process of a data processing method is as follows:

[0137] 201. Obtain texture maps of multiple three-dimensional models.

[0138] The texture maps of multiple three-dimensional models refer to texture maps of two or more three-dimensional models. For example, the texture maps of the multiple three-dimensional models may be texture maps of n game characters, where n is a positive integer greater than 2.

[0139] 202. Integrate the texture maps of multiple three-dimensional models to obtain an integrated texture map.

[0140] The terminal device obtains the preset image size. For example, Figure 2bis a schematic diagram of a user interface of a terminal device provided by an embodiment of the present invention. As shown in the figure, a user can select whether to integrate the texture map in the user interface provided by the game engine of the terminal device. If the user selects to integrate, the preset image size can be set. The selectable image sizes are 256, 512 and 1024. The terminal device responds to the user's operation and obtains the preset image size.

[0141] The terminal device starts the integration process. The terminal device sorts multiple texture maps according to the image size from large to small to obtain a sorted texture map group. The terminal device determines whether there is a texture map in the sorted texture map group. If there is no texture map, the integration process is terminated; if there is a texture map, a blank map of a preset image size is generated. The terminal device obtains the current texture map and inserts the current texture map into the blank map. If the insertion is successful, the current texture map is deleted from the sorted texture map group, the next texture map is determined to be the current texture map, and the step of returning to obtain the current texture map is returned. Furthermore, if the insertion fails, the following implementation method can be referred to.

[0142] In some embodiments, Figure 2c As shown, if the insertion fails, the current texture map is not processed; then it is determined whether there is a next texture map in the current texture map. If there is a next texture map, the next texture map is determined as the current texture map, and the step of inserting the current texture map into the blank map is returned to execute; if there is no next texture map, the step of generating a blank map of a preset image size is returned to execute. During the integration process of the terminal device, when the current texture map fails to be inserted into the blank map, a texture map with a smaller image size than the current texture map is obtained to determine whether it can be inserted into the blank map, thereby improving the utilization rate of the map space.

[0143] In some embodiments, Figure 2d As shown, if the insertion fails, the step of generating a blank texture of a preset image size is returned. When the terminal device fails to insert a blank texture into the current texture image during the integration process, the next integration process is entered, that is, a new blank texture is generated, which can shorten the integration process time.

[0144] A more specific implementation of step 202 may refer to the method described in step 102, which is only briefly explained here.

[0145] 203. Generate a first baking instruction for the integrated texture map, wherein the first baking instruction is not an instruction for invoking a graphics processor to bake the integrated texture map.

[0146] 204. Based on the first baking instruction for the integrated texture map, bake the integrated texture map into an integrated two-dimensional light map. The terminal device sends the first baking instruction and the integrated texture map to the server, and the server is equipped with a graphics processor, so that the server uses the graphics processor to bake the integrated texture map into the integrated two-dimensional light map based on the first baking instruction; the terminal device receives the integrated two-dimensional light map from the server.

[0147] 205. Split the integrated two-dimensional illumination map to obtain a two-dimensional illumination map corresponding to the texture map of each model.

[0148] The two-dimensional illumination map may store illumination information in the form of a texture map, and when rendering a three-dimensional model in a game, the texture map may be applied to the surface of the three-dimensional model.

[0149] like Figure 3 As shown, when the baking object is a lighting sample in a game scene, the specific process of a data processing method is as follows:

[0150] 301. Obtain multiple illumination samples.

[0151] The multiple illumination samples refer to two or more illumination samples. The number of illumination samples is obtained according to the number of illumination information sampling points in the bounding box specified by the user, so the user does not need to configure the size of the integrated illumination samples.

[0152] 302. Integrate the multiple illumination samples to obtain an integrated illumination sample. The terminal device linearly arranges the multiple illumination samples into a group to obtain an integrated illumination sample.

[0153] 303. Generate a second baking instruction for the integrated illumination sample, wherein the second baking instruction is not used to call an instruction for a graphics processor to bake the integrated illumination sample.

[0154] 304. Based on the second baking instruction for the integrated illumination sample, bake the integrated illumination sample into an integrated volumetric illumination map. The terminal device sends the second baking instruction and the integrated illumination sample to the server, and the server is equipped with a graphics processor, so that the server uses the graphics processor to bake the integrated illumination sample into the integrated volumetric illumination map based on the second baking instruction; the terminal device receives the integrated volumetric illumination map from the server.

[0155] 305. Split the integrated volumetric illumination map to obtain a volumetric illumination map corresponding to each illumination sample.

[0156] The volumetric light map may be stored in the form of a light probe. For example, when a game character moves to an area corresponding to a light sample, the surface of the character may display the light information in the volumetric light map corresponding to the light sample.

[0157] The embodiment of the present invention can obtain multiple baking objects, which are objects used to store lighting information; integrate the multiple baking objects to obtain an integrated baking object; generate baking instructions for the integrated baking object; based on the baking instructions for the integrated baking object, bake the integrated baking object into an integrated lighting map; split the integrated lighting map to obtain a lighting map corresponding to each baking object.

[0158] From the above, it can be seen that since the texture maps of multiple models can be integrated into a large texture map, and then the integrated texture map is baked to obtain a lighting map that stores the lighting information of multiple models; then the lighting map is split to obtain the lighting map corresponding to each model; therefore, the graphics processor can bake the texture maps of multiple models at one time; similarly, the lighting samples in the three-dimensional space can be linearly arranged and the arranged lighting samples can be baked, so the graphics processor can bake multiple lighting samples at one time; from the above, when the graphics processor bakes multiple texture maps or multiple lighting samples at one time, more computing units are required for processing, so the computing units of the graphics processor can be fully utilized to avoid the waste caused by the computing units being in an idle state, so that this solution can improve the baking efficiency.

[0159] In order to better implement the above method, an embodiment of the present invention further provides a data processing device, which can be integrated in an electronic device, and the electronic device can be a terminal, a server, etc. Among them, the terminal can be a mobile phone, a tablet computer, a smart Bluetooth device, a laptop, a personal computer, etc.; the server can be a single server or a server cluster composed of multiple servers.
