[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.
[0031] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.
[0032] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0033] In the prior art, it usually relies on UV mapping and static texture of the model. In the specific implementation, the texture is mainly mapped to the 3D model using UV coordinates, and the lighting model is used to calculate the lighting effect.
[0034] Figure 1 A schematic diagram of a texture rendering effect of the prior art provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, it shows the texture rendering effect of the ball model under a certain lighting angle. It can be seen that the texture of the ball model cannot dynamically interact with the ambient lighting.
[0035] In addition, the existing image sampling accuracy is limited by the texture resolution and pattern repetition rate, and lacks flexibility. For example, in the existing technology, when using a map in a game, the usage rate is generally increased, that is, a map is reused. For example, the color map of the entire ground in the game is displayed by using a map to tile and repeat multiple times.
[0036] In view of this, an embodiment of the present application provides a texture rendering method, the application of which can reflect the real-time dynamic interaction effect between the texture and ambient lighting in the model. Furthermore, the texture can be dynamically adjusted according to the lighting direction and intensity, thereby improving the flexibility of the rendering method.
[0037] Figure 2 The present invention provides a flowchart of a texture rendering method according to an embodiment of the present invention. The execution subject of the method can be a computer, a server, a processor, or other electronic device that can perform graphics rendering. Optionally, the present invention method can be applied in the fields of games, movies, and architectural design. In order to better understand the present invention, the following examples are given using the field of games as an example.
[0038] like Figure 1 As shown, the method includes
[0039] Step 101: Obtain at least one layer of basic texture map corresponding to the target model.
[0040] Optionally, the target model may be any model that requires texture rendering, for example, a virtual character model, a virtual equipment model, a virtual building model, a virtual terrain model, etc., which is not limited here.
[0041] In some embodiments, the target model may correspond to one or more layers of basic texture maps, for example, two, three, or five layers of texture, etc., which are not limited here and can be flexibly set according to the actual application scenario; optionally, each layer of basic texture maps can be generated by a programmatic algorithm, or can be generated by UV sampling technology, which is not limited here. Among them, if generated by a programmatic algorithm, each basic texture map can be regarded as a basic program texture map.
[0042] Step 102: In response to the adjustment operation of the illumination parameter and / or the viewing angle parameter, at least one layer of basic texture map is processed to generate at least one layer of mixed texture map corresponding to the target model.
[0043] Among them, the target rendering parameters corresponding to the target model may include lighting parameters and / or viewing angle parameters. Optionally, the lighting parameters may be obtained through the lighting components of the game world where the target model is located. In some embodiments, the specific acquisition may be based on the game engine and obtained through the lighting system in the game engine. In some embodiments, the lighting parameters may include: lighting properties such as light source position, lighting direction, lighting intensity, and lighting color, which may vary according to the actual application scenario; the viewing angle parameters may be obtained through the camera of the game world where the target model is located, and the viewing angle parameters may include: viewing angle direction, wherein the viewing angle direction may represent the player's line of sight direction in the game scene.
[0044] The mixed texture map corresponding to the target model may include multiple layers, for example, one layer, two layers, or more layers, which is not limited here.
[0045] Optionally, each layer of mixed texture map may be obtained by processing at least one layer of basic texture map based on illumination parameters and / or viewing angle parameters.
[0046] In some embodiments, if the illumination parameter and / or the viewing angle parameter are adjusted, in response to the adjustment operation, a corresponding mixed rendering weight may be obtained, and based on the mixed weight, at least one layer of base texture map is mixed pixel by pixel to obtain a corresponding mixed texture map. It is understandable that based on the mixed texture map, when the illumination parameter and / or the viewing angle parameter changes, the texture rendering effect of the mixed texture map may change synchronously.
[0047] It should be noted that, when mixing, multiple layers of basic texture maps can be mixed pixel by pixel based on the mixing weight to obtain a corresponding mixed texture map; or, based on the mixing weight, at least one layer of basic texture map and a preset texture map can be mixed pixel by pixel to obtain a corresponding mixed texture map, which is not limited here and can be flexibly selected according to the actual application scenario. Optionally, the preset texture map can be generated by 3D modeling software, or it can be generated programmatically, which is not limited here.
[0048] Step 103: superimpose at least one layer of basic texture map and at least one layer of mixed texture map on the target model to obtain a texture rendering effect corresponding to the target model.
[0049] Based on the above description, after obtaining each layer of basic texture maps and each layer of mixed texture maps, the each layer of basic texture maps and each layer of mixed texture maps can be superimposed on the target model. It can be understood that due to the setting of the mixed texture maps, at this time, the target model can present a texture rendering effect that can change with lighting parameters and / or viewing angle parameters, thereby realizing real-time dynamic interaction between texture and lighting.
[0050] In summary, an embodiment of the present application provides a texture rendering method, which includes: obtaining at least one layer of basic texture map corresponding to a target model; in response to an adjustment operation on illumination parameters and / or viewing angle parameters, processing at least one layer of basic texture map to generate at least one layer of mixed texture map corresponding to the target model; superimposing at least one layer of basic texture map and at least one layer of mixed texture map on the target model to obtain a texture rendering effect corresponding to the target model, so that when the illumination parameters and / or viewing angle parameters change, the texture rendering effect can change synchronously, that is, for the target model, it is possible to present a texture rendering effect that can change with the viewing angle parameters and / or illumination parameters, thereby realizing real-time dynamic interaction between texture and illumination.
[0051] Figure 3 A flowchart of another texture rendering method provided in an embodiment of the present application. Figure 4 A schematic diagram of a texture rendering effect provided in an embodiment of the present application. Figure 5 A schematic diagram of a texture rendering effect provided by an embodiment of the present application. In an optional implementation, the lighting parameters include: lighting direction and lighting intensity, and the basic texture map includes at least two layers.
[0052] like Figure 3 As shown, in response to the adjustment operation of the illumination parameter and / or the viewing angle parameter, at least one layer of the basic texture map is processed to generate at least one layer of the mixed texture map corresponding to the target model, including:
[0053] Step 201: In response to an adjustment operation on a lighting direction and / or a viewing angle direction, a hybrid rendering weight is calculated according to the adjusted lighting direction and / or viewing angle direction.
[0054] The mixed rendering weight is used as an interpolation factor to mix multiple layers of base textures during the mixing process to obtain a random texture that can change with the viewing direction and / or the lighting direction.
[0055] Optionally, the lighting parameters may include: lighting direction and lighting intensity. When the lighting direction and / or viewing angle direction is adjusted, the mixed rendering weight may be calculated according to the adjusted lighting direction and / or viewing angle direction.
[0056] It should be noted that in some scenes, if only the illumination direction is adjusted, the mixed rendering weight can be recalculated based on the adjusted illumination direction and the existing viewing angle direction; if only the viewing angle direction is adjusted, the mixed rendering weight can be recalculated based on the adjusted viewing angle direction and the existing illumination direction; if both the illumination direction and the viewing angle direction are adjusted, the mixed rendering weight can be recalculated based on the adjusted illumination direction and the viewing angle direction. The calculation method can be flexibly selected according to the actual application scenario.
[0057] Step 202: Perform a blending operation on any two layers of basic texture maps according to the blending rendering weights to obtain a first illumination blending texture map corresponding to the target model.
[0058] Wherein, referring to the above description, the target model may correspond to a multi-layer basic texture map, and the first illumination mixed texture map may be obtained by mixing any two layers of basic texture maps in the multi-layer basic texture map in combination with the mixed rendering weight. Optionally, when performing a specific mixing operation, it may be obtained based on a mixing function such as mix() and lerp().
[0059] For example, in a certain scene, the target model corresponds to two layers of basic texture maps: RandomTextures01 and RandomTextures02. Optionally, the first illumination mixed texture map can be obtained through mixing functions such as mix() and lerp().
[0060] In some embodiments, taking mix() as an example, the implementation code corresponding to the first lighting mixed texture map can be: RandomTexturesWithLight=mix(RandomTextures01, RandomTextures02, VdotL), wherein RandomTextures01 represents the first layer of basic texture map, RandomTextures02 represents the second layer of basic texture map, VdotL represents the mixed rendering weight, and RandomTexturesWithLight represents the first lighting mixed texture map.
[0061] Based on the acquisition process of the first illumination mixed texture map, refer to Figure 4 As shown, taking the target model as a spherical model as an example, if the first lighting mixed texture map is used to render the target model, when the lighting direction and / or viewing direction changes, the texture rendering effect of the first lighting mixed texture map will change synchronously, realizing real-time dynamic interaction between texture and lighting direction, and enhancing the realism and diversity of visual effects.
[0062] It should be noted that the specific implementation method is not limited to the above examples and can be flexibly set according to the actual application scenario.
[0063] Step 203: In response to the adjustment operation on the illumination intensity, a mixing operation is performed on the first illumination mixed texture map and at least one layer of basic texture map based on the adjusted illumination intensity to obtain a second illumination mixed texture map corresponding to the target model.
[0064] Based on the above description, after obtaining the first illumination mixed texture map, the first illumination mixed texture map and at least one layer of basic texture map can be further mixed according to the illumination intensity to obtain the second illumination mixed texture map. Optionally, when performing the mixing operation, it can be obtained based on a mixing function such as mix() and lerp().
[0065] Among them, refer to Figure 5 As shown, taking the target model as a spherical model as an example, if the target model is rendered using the second illumination mixed texture map, it can be seen that when any parameters in the illumination direction, illumination intensity, and viewing direction change, the texture rendering effect of the second illumination mixed texture map will change synchronously, thereby realizing real-time dynamic interaction between texture and illumination.
[0066] In summary, the embodiments of the present application realize that a first lighting mixed texture map can be obtained based on the lighting direction and the viewing direction; a second lighting mixed texture map can be obtained based on the lighting intensity and the first lighting mixed texture map, and then the first lighting mixed texture map, the second lighting mixed texture map and at least one layer of basic texture map are superimposed and rendered, and the texture can be dynamically adjusted according to the lighting direction, lighting intensity and viewing direction.
[0067] It should be noted that the specific mixing method is not limited to the above-mentioned embodiments, and the mixing order can be flexibly adjusted according to the actual application scenario. For example, in some scenarios, in response to the adjustment operation of the light intensity, a mixing operation can be performed on any two layers of basic texture maps to obtain a first lighting mixed texture map corresponding to the target model; in response to the adjustment operation of the lighting direction and / or the viewing angle direction, a mixed rendering weight is calculated according to the adjusted lighting direction and / or the viewing angle direction; according to the mixed rendering weight, a mixing operation is performed on the first lighting mixed texture map and at least one layer of basic texture maps to obtain a second lighting mixed texture map corresponding to the target model.
[0068] In an optional implementation, the above-mentioned calculation of the mixed rendering weight according to the adjusted illumination direction and / or viewing angle direction includes:
[0069] The illumination vector corresponding to the illumination direction and the viewing vector corresponding to the viewing direction are obtained respectively; a dot product is calculated for the illumination vector and the viewing vector, and the dot product calculation result is used as a mixed rendering weight.
[0070] The illumination direction may be represented by an illumination vector, and the viewing angle direction may be represented by a viewing angle vector. Optionally, the illumination vector corresponding to the illumination direction may be obtained by a preset illumination vector obtaining function, and the viewing angle vector corresponding to the viewing angle direction may be obtained by a preset viewing angle vector obtaining function.
[0071] Optionally, the mixed operation of the illumination direction and the viewing direction can be obtained by performing a dot product calculation on the illumination vector and the viewing vector. For example, it can be calculated by the dot() function. The corresponding implementation code can be:
[0072] float VdotL=dot(lightDirection,viewDirection), where lightDirection represents the light vector, and viewDirection represents the view vector. lightDirection can be obtained through the light vector acquisition function GetLightDirection(), and viewDirection can be obtained through the view vector acquisition function GetViewDirection().
[0073] In an optional embodiment, in response to the adjustment operation on the illumination intensity, performing a mixing operation on the first illumination mixed texture map and at least one layer of base texture map based on the adjusted illumination intensity to obtain a second illumination mixed texture map corresponding to the target model includes:
[0074] The adjusted illumination intensity is used as a linear interpolation parameter to perform a blending operation on the first illumination mixed texture map and at least one layer of basic texture map to obtain a second illumination mixed texture map corresponding to the target model.
[0075] Optionally, the second lighting mixed texture map may be mixed based on the first lighting mixed texture map and one or more base texture map textures.
[0076] In order to better understand the present application, the second lighting mixed texture map is obtained by mixing the first lighting mixed texture map and a layer of basic texture map texture as an example for explanation. Optionally, in the specific implementation, the second lighting mixed texture map can be obtained through mixing functions such as mix() and lerp().
[0077] In some embodiments, the implementation code corresponding to the second lighting mixed texture map may be: FinalTexture = mix(RandomTextures03, RandomTexturesWithLight, lightIntensity), wherein RandomTextures03 represents the third layer basic texture map, RandomTexturesWithLight represents the first lighting mixed texture map, lightIntensity represents the light intensity, and FinalTexture represents the second lighting mixed texture map.
[0078] It can be seen that by taking the illumination intensity as a weight and performing a mixing operation on the first illumination mixed texture map and the third layer basic texture map, the second illumination mixed texture map can be obtained.
[0079] Optionally, according to the actual application scenario, the third layer of basic texture map can be set to be the same as or different from the first layer of basic texture map. It can be understood that if they are set to be the same, the generation efficiency of the basic texture map can be improved.
[0080] Figure 6 A schematic diagram of another texture rendering method provided in an embodiment of the present application. In an optional implementation, as Figure 6 As shown, the above-mentioned obtaining at least one layer of basic texture map corresponding to the target model includes:
[0081] Step 301: Based on the material blueprint, a preset noise algorithm is used to fit and generate texture units of multiple basic shapes corresponding to the target model.
[0082] Step 302: Obtain basic texture maps of each layer corresponding to the target model according to the texture units of multiple basic shapes.
[0083] Optionally, each layer of base texture maps can be obtained based on a preset engine, which can include a material blueprint, wherein the material blueprint is a visual programming tool for creating and editing materials, for example, it can build material logic by dragging and dropping nodes and connecting nodes. In some embodiments, the material blueprint can be a component in Unreal Engine for creating and editing materials.
[0084] In some embodiments, during specific acquisition, a plurality of texture units of basic shapes may be calculated by fitting through a preset noise algorithm in a material blueprint, and the plurality of texture units of basic shapes may be arranged to obtain basic texture maps of each layer corresponding to the target model.
[0085] Optionally, the preset noise algorithm may be Perlin Noise, Simplex Noise, Value Noise, Wavelet Noise, etc., which is not limited here and can be flexibly selected according to actual application scenarios.
[0086] Optionally, the basic shape generated by fitting can be a regular shape such as a rectangle, triangle, etc., of course, it can also be an irregular shape, which is not limited here and may vary according to the actual application scenario; the basic texture maps of each layer obtained can specifically be: wood texture, cloth texture, rock texture, metal texture, vegetation texture, gravel texture, etc., which are not limited here.
[0087] It can be seen that the present application can use a preset noise algorithm to generate multi-layer procedural textures. Compared with the prior art, it does not need to rely on model UV sampling and can improve the texture rendering speed. In addition, combined with the above embodiments, since the lighting parameters can be changed at any time to adjust the texture style, it has the characteristics of flexible design.
[0088] In addition, it should be noted that, in some embodiments, multiple trigonometric function superposition, mean filtering, mathematical formula fitting, etc. can also be used to fit and generate texture units, which is not limited here.
[0089] Figure 7 A schematic diagram of another texture rendering method provided in an embodiment of the present application. In an optional implementation, as Figure 7 As shown, the above-mentioned texture units of multiple basic shapes corresponding to the target model are generated based on the material blueprint through a preset noise algorithm fitting, including:
[0090] Step 401: Based on the material blueprint, the size parameters of each texture unit and the corresponding arrangement position of each texture unit are calculated by fitting through a preset noise algorithm.
[0091] The arrangement positions corresponding to the texture units may represent the arrangement positions of the texture units in the basic texture maps of each layer.
[0092] In an optional embodiment, if Figure 7 As shown, the above-mentioned basic texture maps of each layer corresponding to the target model are obtained according to the texture units of multiple basic shapes, including:
[0093] Step 402: Obtain basic texture maps of each layer corresponding to the target model according to the size parameters of each texture unit and the corresponding arrangement positions of each texture unit.
[0094] Optionally, when fitting, the target model can be UV expanded to obtain the UV coordinates corresponding to each vertex in the target model in the UV space, and based on the UV coordinates, the size parameters of each texture unit and the corresponding arrangement position of each texture unit are calculated by fitting through a preset noise algorithm, and a layer of basic texture map is generated accordingly. Referring to the acquisition process, a multi-layer basic texture map can be obtained.
[0095] In some embodiments, the size parameters of each texture unit and the corresponding arrangement position of each texture unit can be determined by participating in the following code:
[0096] float2 blockCenter=UV×(1.0+PerlinNoise(UV×10.0)×0.1);
[0097] float blockSize=4.0×Random(UV×10.0);
[0098] Among them, UV represents the UV coordinates corresponding to the target model, PerlinNoise represents the Perlin noise function, blockCenter represents the arrangement position of each texture unit generated by fitting in the basic texture map, blockSize represents the size parameter of each texture unit generated by fitting, and Random() represents the random number generation function.
[0099] Optionally, the definition of the random number generation function Random() can be seen as follows:
[0100] float Random(float2 p){
[0101] return frac(sin(dot(p,float2(12.9898,78.233)))×43758.5453123);
[0102] }
[0103] Among them, frac() represents the fractional exponential function, sin() represents the trigonometric sine function, and dot() represents the dot product function.
[0104] In some embodiments, each layer of base texture map may include multiple texture units of different sizes.
[0105] It should be noted that, of course, a random number generation function can also be used to perform further random calculations on the size parameters of each texture unit generated above and the corresponding arrangement positions of each texture unit, so as to meet the design requirements in different scenarios and improve the applicability of the method of the present application.
[0106] Figure 8 Another schematic diagram of texture rendering effect provided by an embodiment of the present application. In an optional implementation, the above-mentioned acquisition of each layer of basic texture maps corresponding to the target model according to the size parameters and UV coordinates of each texture unit includes:
[0107] Obtain color parameters of each texture unit; arrange multiple texture units according to the color parameters of each texture unit, the size parameters of each texture unit and the corresponding arrangement positions of each texture unit to obtain basic texture maps of each layer corresponding to the target model.
[0108] Optionally, the color parameter of each texture unit may be determined by a random number generation function, or may be specified by a user, which is not limited here and may be flexibly selected according to actual application scenarios.
[0109] For example, for the first layer of basic texture map, the following code can be used to fill each texture unit in the first layer of basic texture map:
[0110] float RandomTextures01=blockSize×Ramdom(color.r)
[0111] Among them, blockSize represents the texture unit in the first layer of basic texture map, Ramdom() represents the random number generation function, and color.r represents the color single layer channel.
[0112] After obtaining the color parameters of each texture unit, each texture unit can be filled according to the obtained color parameters, and combined with the size parameters of each texture unit and the corresponding arrangement position of each texture unit, the basic texture maps of each layer corresponding to the target model can be obtained, thereby realizing the ability to obtain basic texture maps of any color, thereby improving the applicability of the method of the present application.
[0113] Reference Figure 8 As shown in the figure, the target model is a ball model as an example. Figure 8 As shown, the first layer of basic texture map corresponding to the target model in a certain scene may include multiple block textures of different sizes, and the color of each block texture is determined by a random number generation function. Of course, it should be noted that basic texture maps of other texture styles can also be generated according to actual application scenarios.
[0114] In summary, compared with the prior art, the implementation of the texture rendering method of the present application does not need to rely on model UV sampling. Therefore, it can not only achieve the effect of real-time interaction and dynamic adjustment of ambient lighting, but also improve the rendering speed.
[0115] In an optional implementation, the basic texture map includes multiple layers, and the basic shape and / or size parameters of the texture units corresponding to each layer of the basic texture map are different.
[0116] Optionally, the above-mentioned basic texture map may include multiple layers. In order to achieve design diversity, the basic shape and / or size parameters of the texture units corresponding to each layer of basic texture map may be set to be different, so that each basic texture map can display different texture effects, thereby improving the flexibility and applicability of the method of the present application.
[0117] In summary, in the texture rendering method provided in the present application, there is no need to manually create UV coordinates, the algorithm can automatically adapt to lighting changes, and thus the texture effect can be adjusted in real time according to the ambient lighting to enhance the visual effect; and the calculation of procedural textures can ensure efficient operation on the graphics processing unit (GPU) and improve rendering performance.
