[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are 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.
[0021] Based on this, an embodiment of the present invention provides a model rendering method, device, electronic device and storage medium. This technology can be applied to various model rendering processes, especially to the rendering process of creating a continuous translation effect of long-frame text or patterns.
[0022] To facilitate understanding of this embodiment, a rendering method of a model disclosed in an embodiment of the present invention is first described in detail. Figure 1 As shown, the method comprises the following steps:
[0023] Step S102, obtaining an initial map and a target model; wherein the initial map has a first aspect ratio;
[0024] The above-mentioned target model is a carrier model that carries the initial map content. The corresponding map can be fitted and covered on the surface of the target model to carry the translation effect of the initial map content. The target model can be a three-dimensional model built by mesh connection. Optionally, the three-dimensional model can be a model built by triangular facets, a model built by quadrilateral meshes, or a model built by other polygonal meshes.
[0025] Design the texture content to be rendered as needed to obtain an initial texture. The shape of the initial texture can be determined according to the texture content. For example, if you want to create a continuous translation effect of long text or long pattern, you can create a long and thin texture with the content of the long text or pattern. For example, to create a horizontal translation effect of numbers 1-16, you can design a rectangular texture with numbers 1-16, such as Figure 2 As shown, the characteristic is that the ratio of the length to the width of the map is large.
[0026] Here, the initial texture has a length and a width, the length dimension is greater than the width dimension, and a ratio of the length to the width of the initial texture is a first aspect ratio.
[0027] In this step, an initial map and a target model are obtained, and a ratio of the length to the width of the initial map is determined as a first aspect ratio.
[0028] Step S104, determining a segmentation parameter and an arrangement parameter corresponding to the initial texture, segmenting the initial texture into a plurality of sub-textures according to the segmentation parameter, arranging the plurality of sub-textures according to the arrangement parameter, and generating a target texture; wherein the aspect ratio of the target texture is smaller than the first aspect ratio; the segmentation parameter is used to indicate: the number of the plurality of sub-textures into which the initial texture is segmented; and the arrangement parameter is used to indicate: the arrangement method of the plurality of sub-textures in the target texture;
[0029] The target texture is a target texture whose shape is closer to a square than the shape of the initial texture, which is obtained by slicing the initial texture into a plurality of sub-textures and then splicing them together. The aspect ratio of the target texture is smaller than the first aspect ratio. The slicing parameter is used to indicate: the number of sub-textures into which the initial texture is sliced. Here, the slicing parameter is the number of sub-textures into which the initial texture is sliced. The arrangement parameter is used to indicate: the arrangement of the plurality of sub-textures in the target texture. In one case, if the slicing sub-textures are arranged in a column to obtain a target texture, the arrangement parameter is only the number of rows of the sub-textures contained in the target texture; if the slicing sub-textures are arranged in a row to obtain a target texture, the arrangement parameter is only the number of columns of the sub-textures contained in the target texture. In another case, if the slicing sub-textures are arranged in multiple rows and columns to obtain a target texture closer to a square, the arrangement parameter includes the number of rows and columns of the sub-textures contained in the target texture.
[0030] Here, the segmentation parameters and arrangement parameters corresponding to the initial texture are determined, the initial texture is segmented into a corresponding number of sub-textures according to the segmentation parameters, and these sub-textures are spliced into a target texture whose shape is closer to a square than that of the initial texture according to the arrangement parameters.
[0031] For example, in one method, a segmentation parameter n can be determined according to the first aspect ratio to achieve n equal divisions in the length direction of the initial texture. After the initial texture is cut into n sub-textures of the same size, a target texture with a shape closer to a square can be obtained by arranging the multiple sub-textures in a row in the width direction of the initial texture. For example: if the length and width ratio of the initial texture is 4:1, the initial texture can be divided into 2 equal parts in the length direction, that is, the initial texture is evenly divided into 2 sub-textures of the same size along the length direction perpendicular to the initial texture, and the 2 sub-textures are closely arranged in a row up and down to obtain a square texture with an aspect ratio of 1:1, and the square texture can be used as the target texture.
[0032] Step S106, obtaining a first sampling coordinate of the target model sampled from the initial map, performing coordinate transformation on the first sampling coordinate based on the segmentation parameter and / or the arrangement parameter, and obtaining a second sampling coordinate corresponding to the target map;
[0033] The first sampling coordinates are the sampling coordinates of the target model on the initial texture when the target model is rendered by the initial texture before the initial texture is split to achieve a rendering effect in which the content of the initial texture is translated on the target model. The second sampling coordinates are the sampling coordinates of the target model on the target texture after the initial texture is split and spliced into the target texture.
[0034] Here, according to the generation method of the target map, the segmentation parameter and the arrangement parameter, or one of the segmentation parameter and the arrangement parameter, can be used to perform coordinate transformation on the first sampling coordinate to obtain the second sampling coordinate.
[0035] For example, if the target texture is generated by dividing the length of the initial texture into equal parts, cutting the initial texture into multiple sub-textures of the same size, and arranging the multiple sub-textures in a row in the width direction of the initial texture according to the sequential order of the contents of the sub-textures in the initial texture to obtain a target texture containing multiple rows of sub-textures, then the first sampling coordinates can be transformed only according to the corresponding arrangement parameters to obtain the second sampling coordinates.
[0036] Step S108: sampling the target map based on the second sampling coordinates, and rendering the target model using the rendering data obtained by sampling to obtain a rendering effect of translating the content of the initial map onto the target model.
[0037] Finally, the rendering engine samples the target texture according to the second sampling coordinates, and renders the target model using the rendering data obtained by sampling, thereby obtaining a rendering effect in which the content of the initial texture is translated on the target model. Compared with the initial texture, the target texture is more convenient for the rendering engine to compress the texture of the texture. At the same time, the texture space utilization rate of the target texture is higher, and the entire texture content occupies less memory resources.
[0038] In one embodiment, a method of changing an initial texture into a target texture whose shape is closer to a square than the shape of the initial texture is provided by using a first segmentation parameter and a first arrangement parameter.
[0039] Specifically, based on the first aspect ratio, determine the first segmentation parameter and the first arrangement parameter corresponding to the initial texture; wherein the first segmentation parameter is used to indicate: the number of sub-textures into which the initial texture is evenly segmented along a length direction perpendicular to the initial texture; the first arrangement parameter is used to indicate: the number of rows corresponding to when the multiple sub-textures are generated by arranging them in a row along the width direction of the initial texture in accordance with the consecutive order of the contents of the sub-textures in the initial texture.
[0040] In this method, if Figure 3 As shown, a first segmentation parameter n can be determined according to the first aspect ratio, and the initial texture is divided into n equal parts along the length direction perpendicular to the length direction of the initial texture, and the initial texture is cut into n sub-textures of the same size. According to the continuous order of the contents of the sub-textures in the initial texture, multiple sub-textures are arranged in a row in the width direction of the initial texture to obtain a target texture, and the shape of the target texture is closer to a square. In this method, the first arrangement parameter is the number of rows corresponding to arranging multiple sub-textures in a row along the width direction of the initial texture according to the continuous order of the contents of the sub-textures in the initial texture. The value of the first arrangement parameter is equal to the value of the first segmentation parameter n.
[0041] Specifically, the first segmentation parameter and the first arrangement parameter may be determined according to the following method:
[0042] Perform an arithmetic square root operation on the first aspect ratio to obtain a first operation result; determine a first integer value based on the first operation result; wherein a difference between the first integer value and the first operation result is smaller than a difference between other integers other than the first integer value in natural numbers and the first operation result; determine the first integer value as a first segmentation parameter; and determine a first arrangement parameter based on the first segmentation parameter.
[0043] That is to say, an arithmetic square root operation is performed on the first aspect ratio to obtain a first operation result, and an integer closest to the first operation result is determined as the first integer value, such as integer n. The integer n is used as the first segmentation parameter, and the first arrangement parameter is the number of rows n corresponding to when multiple sub-maps are arranged in a row in the width direction of the initial map according to the consecutive order of the contents of the sub-maps in the initial map.
[0044] After determining the first segmentation parameter and the first arrangement parameter, the initial texture is divided into n equal parts in the length direction, and the initial texture is cut into n sub-textures of the same size. According to the continuous order of the contents of the sub-textures in the initial texture, the multiple sub-textures are arranged in a row in the width direction of the initial texture to obtain a target texture containing n rows of sub-textures. The shape of the target texture is closer to a square than the initial texture.
[0045] For example, Figure 2 The initial texture shown in the figure contains a rectangular texture with numbers 1-16. The ratio of the length to the width of the texture is 14:1. Perform a square root operation on 14 to determine the The nearest integer is 4, so the initial texture is divided into 4 equal parts in the length direction, and the initial texture is cut into 4 sub-textures of the same size. According to the continuous order of the sub-texture contents in the initial texture, multiple sub-textures are closely arranged in a row in the width direction of the initial texture to obtain a target texture containing 4 rows of sub-textures. The generation method of the target texture is as follows: Figure 4 shown.
[0046] In this method, the initial texture is divided into multiple sub-textures according to the first segmentation parameter, and the multiple sub-textures are arranged according to the first arrangement parameter to generate a target texture whose shape is closer to a square than the shape of the initial texture. The target model can be rendered according to the target texture to obtain a rendering effect in which the content of the initial texture is translated on the target model. Since the shape of the target texture is closer to a square than the initial texture, when the target texture is stretched into a square texture, the stretching degree is small, thereby avoiding reducing the utilization rate of the texture space and reducing the memory resources occupied by the entire texture content.
[0047] In one method, after the target texture is generated, if the aspect ratio of the target texture is not 1, the target texture is stretched along the width direction of the target texture to stretch the aspect ratio of the target texture to 1.
[0048] That is to say, if the shape of the target map obtained by dividing and splicing the initial map is not a square, the target map needs to be stretched along the width direction of the target map to stretch the shape of the target map into a square to facilitate the rendering engine to compress the texture of the map.
[0049] In this method, since the shape of the target texture is closer to a square than the initial texture, when the target texture is stretched into a square texture, the stretching degree is small, thereby reducing the occupied texture space.
[0050] The following embodiments provide an implementation method for obtaining the first sampling coordinates.
[0051] Specifically, the texture coordinates of the target model, as well as the content tiling density and the content translation speed are obtained; wherein the content tiling density indicates: the arrangement density of the content of the initial map on the target model; the content translation speed indicates: the translation speed of the content of the initial map on the target model; the texture coordinates are offset based on the time parameter, the content tiling density and the content translation speed to obtain the first sampling coordinates; wherein the time parameter is used to indicate: the time elapsed after the target model is sampled from the initial map.
[0052] In order to achieve the preset translation effect, it is necessary to pre-set the content tiling density and content translation speed. The above content tiling density indicates the arrangement density of the content of the initial map on the target model. For example, if you want to make a translation effect of numbers 1-16 extending in the horizontal direction, the content tiling density can be the number of numbers displayed on the target model at the same time. The content translation speed indicates the translation speed value and translation direction of the content of the initial map on the target model, such as the movement speed value and movement direction of the numbers in the digital translation effect. The texture coordinates of the above target model refer to the UV coordinates of the target model unfolded in the modeling software. The UV coordinates are the range between 0 and 1 on the x and y axes. Using the UV coordinates, each point on the map can be accurately matched to the surface of the target model, so that the target model can present the corresponding visual effect. The above time parameter is the time after the target model starts sampling from the initial map.
[0053] Here, the texture coordinates of the target model, the content tiling density, and the content translation speed are obtained. The texture coordinates of the target model are offset based on the time parameter, the content tiling density, and the content translation speed for the abscissa value in the texture coordinates to obtain the first sampling coordinates.
[0054] Specifically, the texture coordinates may be offset in the following manner to obtain the first sampling coordinates:
[0055] For the horizontal coordinate value in the texture coordinate, the horizontal coordinate value in the texture coordinate is offset based on the time parameter, the content tiling density, and the content translation speed to obtain a first offset result; the decimal part corresponding to the first offset result is determined as the horizontal coordinate value of the first sampling coordinate; the vertical coordinate value in the texture coordinate is determined as the vertical coordinate value of the first sampling coordinate to obtain the first sampling coordinate.
[0056] In actual implementation, the first sampling coordinates can be obtained by the following algorithm:
[0057] UVX0=frac(UV.x*patternDensity+Time*patternSpeed);
[0058] UVNew00=float2(UVX0,UV.y);
[0059] Among them, the frac() function is used to extract the decimal part of its internal function value; UV.x is the horizontal coordinate value in the texture coordinate; patternDensity is the content tiling density; Time is the time parameter; patternSpeed is the content translation speed; UVX0 is the horizontal coordinate value in the first sampling coordinate; UV.y is the vertical coordinate value in the first sampling coordinate; UVNew00 is the first sampling coordinate.
[0060] After the first sampling coordinates are obtained in the above manner, it is necessary to perform coordinate transformation on the first sampling coordinates to determine the second sampling coordinates corresponding to the target map.
[0061] Specifically, the arrangement parameters include a first arrangement parameter, which is used to indicate: the number of rows corresponding to arranging multiple sub-maps in a column along the width direction of the initial map according to the consecutive order of the contents of the sub-maps in the initial map; and performing coordinate transformation on the first sampling coordinate based on the first arrangement parameter to obtain the second sampling coordinate corresponding to the target map.
[0062] That is, if the target texture is a target texture containing multiple rows of sub-textures obtained by equally dividing the length of the initial texture into multiple sub-textures of the same size, and arranging the multiple sub-textures in a row in the width direction of the initial texture according to the sequential order of the contents of the sub-textures in the initial texture, then the first sampling coordinates can be transformed only according to the first arrangement parameter to obtain the second sampling coordinates corresponding to the target texture.
[0063] Specifically, the horizontal coordinate value in the first sampling coordinate is multiplied by the first arrangement parameter to obtain a second operation result; the decimal part in the second operation result is determined as the sampling horizontal coordinate value in the second sampling coordinate; based on the second operation result and the first arrangement parameter, the vertical coordinate value in the first sampling coordinate is offset to obtain the sampling vertical coordinate value in the second sampling coordinate.
[0064] In actual implementation, the sampling horizontal coordinate value in the second sampling coordinate can be obtained by the following algorithm:
[0065] UVXF = UVNew00.x*RowNum;
[0066] UVX = frac(UVXF);
[0067] Among them, UVXF is the second operation result; UVNew00.x is the horizontal coordinate value in the first sampling coordinate; RowNum is the first arrangement parameter; UVX is the sampling horizontal coordinate value in the second sampling coordinate; the frac() function is used to extract the decimal part of its internal function value.
[0068] Further, according to the second operation result and the first arrangement parameter, the ordinate value in the first sampling coordinate is offset to obtain the sampling ordinate value in the second sampling coordinate. The specific method is:
[0069] The integer part of the second operation result is obtained, and the ordinate value in the first sampling coordinate is added to the integer part in the second operation result to obtain a first addition result, and the ratio of the first addition result to the first arrangement parameter is used as the sampling ordinate value in the second sampling coordinate.
[0070] In actual implementation, the sampling ordinate value in the second sampling coordinate can be obtained by the following algorithm:
[0071] UVY=(UVNew00.y+floor(UVXF)) / RowNum;
[0072] Among them, UVNew00.y is the vertical coordinate value in the aforementioned first sampling coordinate; the floor() function is used to extract the integer part of its internal function value; UVXF is the aforementioned second operation result; and RowNum is the first arrangement parameter.
[0073] According to the above method, the sampling horizontal coordinate value and the sampling vertical coordinate value in the second sampling coordinate can be obtained respectively, and the second sampling coordinate can be obtained by sampling the horizontal coordinate value and the sampling vertical coordinate value. The target map is sampled according to the second sampling coordinate, and the target model is rendered by the rendering data obtained by sampling, so as to obtain the rendering effect of translating the content of the initial map on the target model.
[0074] The specific algorithm is:
[0075] UVNew = float(UVX, UVY);
[0076] output=sample(Texture,UVNew);
[0077] Among them, UVNew is the second sampling coordinate; Texture is the target texture; Sample() is the sampling texture function built into the rendering engine; output is the output sampling result, that is, the rendering data obtained by sampling.
[0078] In this method, the length of the initial texture is divided into equal parts, and the initial texture is cut into multiple sub-textures of the same size. According to the continuous order of the contents of the sub-textures in the initial texture, the multiple sub-textures are arranged in a row in the width direction of the initial texture to obtain a target texture containing multiple rows of sub-textures, and then the sampling coordinates of the target model on the initial texture are converted according to the corresponding arrangement parameters to obtain the sampling coordinates of the target model on the target texture. In this method, the arrangement density of the contents of the initial texture on the target model can be conveniently controlled by adjusting the content tiling density, and the speed and direction of the contents of the initial texture can be controlled by adjusting the content translation speed, so as to obtain the rendering effect of the translation of the contents of the initial texture on the target model.
[0079] This method improves the utilization of the texture space during rendering without affecting the translation effect of the initial texture content on the target model, and avoids the entire texture content occupying more memory resources.
[0080] Corresponding to the above method embodiment, see Figure 5 A schematic diagram of a rendering device of a model shown, the device comprising:
[0081] A first acquisition module 502 is used to acquire an initial map and a target model; wherein the initial map has a first aspect ratio;

This method segments and splices the initial texture into a target texture with a shape closer to a square, and then renders the target model according to the target texture to obtain a rendering effect of the content of the initial texture being translated on the target model. This method improves the utilization rate of the texture space during rendering without affecting the translation effect of the content of the initial texture on the target model, and avoids the entire texture content occupying more memory resources.
[0086] The first generation module is used to determine the first segmentation parameter and the first arrangement parameter corresponding to the initial texture based on the first aspect ratio; wherein the first segmentation parameter is used to indicate: the number of sub-textures into which the initial texture is evenly segmented along the length direction perpendicular to the initial texture; and the first arrangement parameter is used to indicate: the number of rows corresponding to arranging the multiple sub-textures in a row along the width direction of the initial texture according to the continuous order of the contents of the sub-textures in the initial texture.
