For example, in scenarios such as industrial model preview and games, users can use the tools provided by the application to draw various patterns on the virtual object model.

[0003] In existing technologies, when an application renders a model based on a pattern drawn by the user, it is usually necessary to first split the model into multiple meshes and then assign corresponding attributes to different meshes, or use multiple maps (masks) to distinguish different areas. However, this method of splitting multiple meshes and generating multiple maps requires a lot of work, and the edges of the rendered model are prone to jagged edges. At the same time, the application has high requirements for device performance and video memory during the rendering process. Summary of the Invention

[0022] The following describes embodiments of the present disclosure in more detail with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments described herein.

[0026] The names of the messages or information exchanged between multiple devices in the embodiments of the present disclosure are only used for illustrative purposes and are not used to limit the scope of these messages or information.

[0027] Before introducing the present technical solution, an example description of the application scenario of the embodiment of the present disclosure may be given.

[0028] For example, in some game application scenarios, when a user draws a pattern on an object model according to his or her own wishes through the functions provided by the application, the application usually needs to split the model of the object into multiple meshes and assign different materials to each mesh before the object can be rendered together with the pattern of the user's receipt to the display interface; or, in an industrial model preview application scenario, when a user customizes the colors of various parts of a certain mechanical component according to business needs, the application can use multiple maps (masks) to enable the shader to distinguish different areas of the mechanical component. However, in both of the above methods, the application requires a more complex process to generate corresponding materials for the corresponding areas on the model, and the above process has higher performance requirements for the hardware. At this time, based on the solution of the embodiment of the present disclosure, when it is detected that the user triggers the model, the category of the contact can be determined by directly performing numerical analysis on the properties of the contact, so that the model can be rendered to the corresponding display interface according to the user's needs.

[0029] Figure 1 This is a flow chart of a method for rendering an image provided by an embodiment of the present disclosure. The embodiment of the present disclosure is applicable to situations where the category of the touch point is determined based on the user's touch, thereby rendering the model. The method can be executed by a device for rendering the image, which can be implemented in the form of software and / or hardware. Optionally, it can be implemented by an electronic device, which can be a mobile terminal, PC or server, etc.

[0030] like Figure 1 As shown, the method includes:

[0031] S110 , when a to-be-processed object model on a trigger display interface is detected, a target contact point on the to-be-processed object model is determined, and a current display attribute of the target contact point is numerically analyzed to determine a target category of the target contact point.

[0032] Among them, the device for executing the method for rendering an image provided by the embodiment of the present disclosure can be integrated into an application software that supports the image rendering processing function, and the software can be installed in an electronic device. Optionally, the electronic device can be a mobile terminal or a PC, etc. The application software can be a type of software for image / video processing. The specific application software will not be described here one by one, as long as the image / video processing can be achieved. It can also be a specially developed application to implement the software for adding special effects and displaying the special effects, or it can be integrated into the corresponding page, and the user can process the special effects video through the page integrated in the PC.

[0033] In this embodiment, the model of the object to be processed can be a pre-built 3D model. At the same time, the model can be integrated into the application after associating it with a corresponding identifier (such as an icon or text, etc.). When the user selects the identifier corresponding to the model of the object to be processed, the application can retrieve the model and present it on the display interface. Based on this, the user can touch the displayed model and then draw a specific pattern on a certain area on the surface of the model, or adjust the material (such as texture or color) on a certain area on the surface of the model.

[0034] It should be noted that before processing the object model to be processed, the object model to be processed can be generated first, and optionally, the map to be used corresponding to the object model to be processed is determined; the map to be used is rendered based on the rendering equation to obtain the object model to be processed displayed on the display interface.

[0035] Among them, the map to be used can be generated based on a blank map, and the blank map can be an image that is pre-generated and bound to the object model after the Digital Content Creation (DCC) software loads the object model to be processed. Those skilled in the art should understand that the scope of DCC includes two-dimensional / three-dimensional animation, audio / video editing and synthesis, DVD creation, dynamic / interactive content creation, image editing and other fields. Therefore, in addition to blank maps, various types of images can be generated based on DCC software and bound to the model, such as solid-color static images or dynamic images containing multiple colors.

[0036] At the same time, the user draws a corresponding pattern on the surface of the object model to be processed, or when the material of the surface of the object model to be processed is adjusted, the result of the drawing or adjustment can be synchronized to the map to be used. Specifically, in the process of determining the map to be used, the current drawing position of the brush position on the object model to be processed can be determined first, and the target face corresponding to the current position drawing can be determined. Among them, the brush is a tool used for drawing in image editing software, and the face refers to the mesh in the application software that supports image rendering processing, which can be understood as the object used to carry the image in the application software. Each face is composed of two triangles. Accordingly, a face contains 12 vertices and two front and back faces. It can be understood that the front and back faces of the face each contain 6 vertices. At the same time, the model to be processed is composed of at least one face. Based on this, after the application determines the pattern drawn by the user, it can associate the pattern with a specific face of the model to be processed, and the associated face is the target face. For example, when the object model to be processed is a model of a sneaker, the user can select a brush in the application software and then draw a circle on the upper of the sneaker model. During the drawing process, the application can determine the drawing position of the brush in real time, so that the circle drawn by the user on the upper is associated with the surface patch of the upper. It can be understood that the surface patch of the upper is the target surface patch.

[0037] Furthermore, after determining the map to be used and its corresponding target face, the target rendering category corresponding to the current drawing position can be determined based on the target face, the preset drawing radius, the drawing color, and the numerical analysis method; and the map to be used is determined based on each target rendering category and the corresponding drawing color. Among them, the preset drawing radius can be a parameter reflecting the size of the brush. It can be understood that the contact surface of the brush on the object model to be processed can be a circle, and the radius of the circle is the preset drawing radius. At the same time, this circle can correspond to a pixel point or an area on the model. Of course, in actual application, the preset drawing radius can be adjusted according to the actual needs of the user. The embodiment of the present disclosure does not make specific limitations here. For example, when the user wants to draw thicker lines on the surface of the object model to be used, a brush with a larger contact surface with the model surface can be selected. Accordingly, the preset drawing radius of this brush is also larger. Conversely, when the user wants to draw thinner lines on the surface of the object model to be used, a brush with a smaller contact surface with the model surface can be selected. Accordingly, the preset drawing radius of this brush is also smaller. The drawing color reflects the color selected by the user during the drawing process. For example, when the user selects red as the color corresponding to the brush, the application software can determine that the current drawing color is red.

[0038] In this embodiment, after the application determines the target face, the preset drawing radius, and the drawing color, the numerical analysis method can be used to process the above information, wherein numerical analysis can be understood as a numerical calculation method based on a computer to solve computational problems. In actual applications, the numerical analysis method can be embodied based on a pre-written program. For example, after determining the above information, the application can run the program corresponding to the numerical analysis method to determine the target rendering category corresponding to the current drawing position.

[0039] The rendering category is information representing a specific area on the object model to be processed. The object model to be processed includes at least one category to be rendered, and the map to be used includes the color scale value corresponding to each pixel. Those skilled in the art will understand that color scale is an index that represents the brightness of an image, namely a color index. In digital image processing, it also refers to the grayscale resolution of a pixel. Therefore, the color scale value corresponding to each pixel in the map to be used determines the color richness and fineness of the image. Continuing with the sneaker example mentioned above, after the user draws a circle on the model, the application runs the corresponding program for the numerical analysis method and determines that the rendering category corresponding to the drawn circle is the upper. Once the target rendering category is determined, the application can obtain the map to be used based on the corresponding drawing color. For example, if the drawing color on the upper is determined to be red, the corresponding map to be used can be determined for the upper portion of the sneaker model. It can be understood that each point in the map corresponds to each pixel in the corresponding area on the model. Therefore, the above process also automatically maps the drawing result to the map to be used.

[0040] In this embodiment, once the application obtains the texture to be used, it can render the texture to be used based on the rendering equation to obtain the object model to be processed and displayed on the display interface. Optionally, the color scale value of each pixel in the texture to be used is obtained, and the first numerical distance metric function and the second numerical distance metric function are respectively used to determine the numerical precision corresponding to the pixel; the numerical precision is processed based on the step function in the graphics processor to determine the target rendering category corresponding to each pixel; and the model to be processed displayed on the display interface is determined based on the drawing color corresponding to the target rendering category.

[0041] Specifically, after the application determines the color scale value of each pixel in the map to be used, the numerical accuracy corresponding to the pixel can be determined based on the two functions. Among them, the first numerical distance metric function can be The second numerical distance metric function can be Among them, I1 can represent the point in the map to be used, that is, the RGB value of the point in the two-dimensional image, and I2 can represent the point on the object model to be processed, that is, the RGB value of the point in the three-dimensional model. The above two numerical distance measurement functions are used to calculate the distance error between pixel RGB. For example, the distance d1(I1, I2) is the distance from a point to X and then to Y, and the distance d2(I1, I2) is the distance between X and Y.

[0042] In this embodiment, based on the above two functions, the application can determine the numerical precision of the pixel point, where numerical precision refers to the degree of approximation between the observed value and the true value, or what can be considered the true value. It can be understood that in the OpenGL Shading Language (GLSL), the lowp precision of the shader is accurate to two decimal places, so values ​​0 to 255 are scaled to lowp floating-point numbers between 0 and 1. This means that the "equal to" operation in the logical method is unreliable and requires a logical operation method more suitable for floating-point numbers. Therefore, the step function in the Graphics Processing Unit (GPU) can be used to process numerical precision. It can be understood that the step function in GLSL is suitable for logical operations on floating-point numbers. When using this function, it is necessary to provide two values ​​corresponding to the function, x and edge. If x is greater than edge, it returns 1, and if x is less than edge, it returns 0, thereby achieving the function of converting numerical precision into logical distance (i.e., 0 or 1).

[0043] In actual applications, after numerical precision processing based on a step function, at least two target rendering types can be determined. For example, the rendering types corresponding to the upper, sole, and shoelaces of a sneaker can be determined. Furthermore, based on the corresponding rendering colors for each rendering type, a model to be processed can be obtained. The model to be processed is the model on the display interface that the application ultimately renders, for example, a 3D image of a sneaker with a red upper, white laces, and a black sole.

[0044] In this embodiment, the application may further determine a material map corresponding to the object model to be processed, so as to render the object model to be processed displayed on the display interface based on the material map and the map to be used.

[0045] The material map can be a map that reflects the texture and color of a specific material. For example, if the object model to be processed is a sneaker model, the corresponding material map can be a map that reflects the texture and color of leather. Once the application software determines the map to be used that corresponds to the object model to be processed, it can overlay the material map with the map to be used to generate a pattern on the surface of the object model to be processed and render it.

[0046] For example, when it is determined that the material map corresponding to the sneaker model is a leather material map, the map can be mixed and superimposed with the map to be used, which is determined based on the user's drawing results on the model and contains a red circular pattern, to obtain an image for rendering the surface of the sneaker model. After the sneaker model is retrieved, sneakers with the above-mentioned red circular pattern and leather texture material can be rendered on the display interface based on the image.

[0047] In this embodiment, after the application determines the material map, the material map and the map to be used can also be rendered based on the rendering equation to obtain a model of the object to be processed. Among them, the material map includes material parameters corresponding to the target rendering category. Those skilled in the art should understand that the material parameters may include many parameters such as texture, color, brightness, etc., and the present embodiment does not make specific limitations here. The rendering equation is an integral equation in computer graphics. It is the theoretical basis of all global illumination methods (such as ray tracing, path based, and radiosity, etc.). Based on this, it can be understood that in computer graphics, the goal of realistic rendering is to solve the above rendering equation.

[0048] For example, when the application determines that the material map corresponding to the sneakers is a leather texture material map, and generates the corresponding map to be used based on the user's drawing results on the sneaker model, it can call a pre-written program that reflects the rendering equation to process the above-mentioned leather texture material map and the map to be used, and obtain the information of each pixel point on the model. After passing the information of each pixel point to the GPU, the sneakers as the object model to be processed can be rendered, and the rendering results can be displayed on the display interface.

[0049] In this embodiment, the method of determining the contact point and then determining the target category can be to determine the target vertex corresponding to the target contact point, and determine the map pixel point corresponding to the target vertex; determine the map pixel point and the corresponding numerical precision value based on the first numerical distance measurement function and the second numerical distance measurement function, and determine the target category corresponding to the target numerical precision based on the step function.

[0050] Among them, the target vertex corresponding to the target contact point can be reflected in the UV texture space. Those skilled in the art should understand that when UVs are used as two-dimensional texture coordinate points residing on the vertices of the polygonal mesh, a two-dimensional texture coordinate system is defined, and this coordinate system is the UV texture space. In this space, U and V are used to define the coordinate axes to determine how to place a texture image on the three-dimensional model surface. In other words, UVs provide a connection between the model surface and the texture image, and are responsible for determining which vertex on the model surface a pixel point on the texture image should be placed, so that the entire texture can be covered on the model.

[0051] Based on this, when the application determines the target vertex, the map pixel point corresponding to the vertex, that is, the pixel UV, can be determined through rasterization processing. Among them, rasterization is the process of converting the set data into pixels after a series of transformations, so that the corresponding pattern is presented on the display interface. The essence of rasterization is coordinate transformation and geometric discretization. In the rasterization process, it is necessary to ensure that each pixel is correctly mapped to the corresponding pixel point or area. After obtaining the pixel UV, the pixel point of the map can be determined based on the first numerical distance function and the second numerical distance metric function described in the embodiment of the present disclosure, so as to obtain the corresponding numerical precision value of the pixel UV point. This process can be understood as a process of re-determining the numerical precision value of a pixel point in a two-dimensional plane based on an inverse function, and then judging the target category to which the pixel point belongs based on the numerical precision value.

[0052] Continuing with the example of a sports shoe model as the object model to be processed, when it is determined that the target vertex UV corresponding to the target contact point corresponds to a certain position on the shoe upper, the mapping pixel point corresponding to the vertex UV can be determined at the same time. Furthermore, the numerical precision value corresponding to the point is determined based on the first numerical distance measurement function and the second numerical distance measurement function (such as 0.9), and then the numerical precision value is processed based on the step function to obtain an integer corresponding to the value, thereby determining that the category information corresponding to this integer is the shoe upper category.

[0053] S120 , determining a target display attribute corresponding to the target category, and rendering the object model to be processed based on the target display attribute to obtain a target image.

[0054] In this embodiment, after the application determines the target category, it can further determine the target display attributes corresponding to the category. Among them, the target display attributes can be information that characterizes the pixel attributes corresponding to the category, such as the pixel color. Furthermore, the target attribute information can be sent to the shader used to render the image, thereby generating a target image that contains the pattern drawn by the user and reflects the model of the object to be processed. Among them, the shader is a programmable program used for image rendering and replaces the fixed rendering pipeline, and is mainly responsible for the geometric operations of each pixel in the model. Those skilled in the art should understand that only one shader can be activated at the same time. At the same time, when the shader is running in the GPU, the corresponding image can be rendered in the display interface. The embodiments of the present disclosure will not be repeated here.

[0055] Optionally, the target display color and target material triggered on the display interface are obtained as target display attributes; the target rendering area corresponding to the target classification is determined, and the target rendering area on the object model to be processed is rendered based on the graphics processor to obtain a target image.

[0056] Among them, the target display color and target material can be determined according to the trigger operation of the user on the display interface. For example, when the user clicks the drop-down list corresponding to the color on the display interface and selects red, and further clicks the drop-down list corresponding to the material on the display interface and selects leather material, the application can determine that the target display color is red and the target material is leather material based on the user's selection results.

[0057] In this embodiment, after the application determines the target display color and target material, the above two types of information can be integrated as the target display attributes. Further, the target rendering area corresponding to the target classification is determined, wherein the target rendering area is the area that needs to be rendered based on the GPU. At the same time, each rendering area has corresponding classification information corresponding to it. For example, when the determined target classification is the upper category, the application can determine that the upper area on the sports shoe model is the target rendering area based on the upper category information. Accordingly, the image obtained by rendering this area is the target image. It can be understood that the target image is at least used to present the pattern corresponding to the target rendering area.

[0058] After determining the target rendering area, the application can further send information about the multiple pixels contained in the area to the GPU's shader, thereby rendering the target rendering area based on the shader and displaying the image containing the target rendering area on the display interface. Continuing with the above example, when determining that the target rendering area is the upper area of ​​a sneaker, the application can send information about the pixels corresponding to the area to the GPU, thereby rendering the image corresponding to the sneaker model based on the shader, and the rendered image at least includes the pattern corresponding to the upper.

[0059] In actual application, you can also follow Figure 2 The schematic diagram shown implements the solution of the embodiment of the present disclosure. Figure 2 In the process of rendering the target image, the application can first obtain the target vertex UV, and further, perform rasterization processing on the vertex UV to obtain the corresponding pixel UV. It can be understood that this process is the process of pasting the two-dimensional map back to the 3D model through grid point mapping. Furthermore, the pixel UV, texture information and the pre-generated map (mask) to be used corresponding to the object model to be processed are combined for sampling processing to obtain the attribute information of each pixel point, and the mask value corresponding to each pixel point can also be obtained. That is to say, after the numerical analysis can analyze the difference between the two mask values, the two mask values ​​can represent a category respectively, achieving the purpose of one value representing two categories. Based on this, if N mask values ​​can be distinguished through numerical analysis, then these N values ​​can represent N categories. The specific numerical analysis scheme can be implemented according to the above description of the embodiment of the present disclosure, and will not be repeated here.

[0060] Continue to see Figure 2 When the application obtains the mask value corresponding to each pixel, it can perform numerical analysis on these values ​​to calculate the corresponding material category, and select the rendering equation based on the adaptability of the calculated material category. Finally, by solving the rendering equation, the color of each pixel reflected by a specific material can be obtained, allowing users to achieve customized color interaction based on application software.

[0061] The technical solution of the embodiment of the present disclosure is that when a model of an object to be processed on a trigger display interface is detected, a target contact on the model of the object to be processed is determined, that is, which area of ​​the object to be processed the user wants to be processed is determined, and further, the current display properties of the target contact are numerically analyzed to determine the target category of the target contact, thereby determining the target display properties corresponding to the target category, and rendering the model of the object to be processed based on the target display properties. By performing numerical analysis on the display properties of the contact, the tedious process of splitting the model into multiple grids during the image rendering process is avoided, thereby avoiding the problem of jagged edges on the boundaries of the rendered model. At the same time, the amount of calculation in the rendering process is reduced, and the application's requirements for hardware performance and video memory are indirectly reduced.
