Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities.

[0031] In view of the problems existing in the related art, the present disclosure proposes a model rendering method. Figure 1 The schematic diagram of the flow chart of the model rendering method in the embodiment of the present disclosure is shown as follows: Figure 1 As shown, the model rendering method includes at least the following steps:

[0032] Step S110. Obtain an initial pattern image, and convert the initial pattern image into a pattern grayscale image; wherein the initial pattern image has a complex pattern structure.

[0033] Step S120: Generate a three-dimensional model with a pattern structure based on the pattern grayscale image.

[0034] Step S130: Determine the target material represented by the initial pattern image, and render a target model having a material effect corresponding to the target material based on the target material and the three-dimensional model.

[0035] In the method and device provided by the exemplary embodiments of the present disclosure, an initial pattern image is obtained, the initial pattern image is converted into a pattern grayscale image, a three-dimensional model with a pattern structure is generated based on the pattern grayscale image, a target material represented by the initial pattern image is determined, and based on the target material and the three-dimensional model, a target model with a material effect corresponding to the target material is rendered. On the one hand, the generation method based on the pattern grayscale image speeds up the speed of generating the three-dimensional model with a pattern structure; on the other hand, after having the initial pattern image, a target model with material effects and a complex pattern structure can be rendered, which reduces the complexity of the rendering process, shortens the rendering cycle and the rendering cost; on another hand, if a new target model needs to be rendered later, it is only necessary to change the initial pattern image, which is convenient for adjusting the rendering result.

[0036] The following is a detailed description of each step of the model rendering method.

[0037] In step S110, an initial pattern image is obtained, and the initial pattern image is converted into a pattern grayscale image; wherein the initial pattern image has a complex pattern structure.

[0038] In an exemplary embodiment of the present disclosure, the initial pattern image refers to an image with a complex pattern structure, and the complex pattern structure meets the requirements for certain assets in the game. For example, Figure 2 The initial pattern picture in the embodiment of the present disclosure is schematically shown, wherein, Figure 2 As shown, the pattern structure in the initial pattern image is relatively complex, consisting of many different shapes in different combinations.

[0039] It is worth noting that the initial pattern image can be a picture designed by an artist or a picture downloaded from a resource pool. The initial pattern image can be a relief image with a complex pattern structure, a painting with a complex pattern structure, or a gun with a complex pattern structure. This exemplary embodiment does not make any special limitations on this.

[0040] After obtaining the initial pattern image, in order to generate a 3D model later, the initial pattern image needs to be converted into a pattern grayscale image. The initial pattern image has corresponding colors, and the converted pattern grayscale image only has gray and white. For example, using a grayscale image conversion tool (such as RreamMaker software), you can Figure 2 Convert to get Figure 3 Grayscale image of the pattern shown.

[0041] In an optional embodiment, the initial pattern image is a blurred image; before converting the initial pattern image into a pattern grayscale image, the method also includes: determining a model size requirement, and adjusting the size of the initial pattern image according to the model size requirement; and adjusting the clarity of the adjusted initial pattern image to obtain a target pattern image with a clear pattern structure.

[0042] The initial pattern image may be a blurred image.

[0043] Based on this, in order to clearly display the complex pattern structure, the clarity of the initial pattern image needs to be adjusted. Before adjusting the clarity, the model size of the initial pattern image is adjusted according to the model size requirements, so that the adjusted initial pattern image can be smoothly imported into the corresponding software (such as RreamMaker software).

[0044] After the adjusted initial pattern image is imported into the corresponding software, the software is used to improve its clarity to obtain a target pattern image that can clearly display the complex pattern structure.

[0045] For example, Figure 4 The following is a schematic diagram of software for adjusting the clarity of the initial pattern image in an embodiment of the present disclosure, as shown in FIG. Figure 4 As shown, the size of the initial pattern image can be adjusted by sliding the control 410, and the clarity of the initial pattern image after the size adjustment can be adjusted by sliding the control 420, so as to finally obtain the following Figure 5 The target pattern image with a clear pattern structure is shown in FIG. Then, the target pattern image is converted into Figure 3 Grayscale image of the pattern shown.

[0046] In step S120, a three-dimensional model having a pattern structure is generated based on the pattern grayscale image.

[0047] In the exemplary embodiments of the present disclosure, the grayscale image is also called a height map. The darker the color in the pattern grayscale image, the lighter the color in the three-dimensional model, and the whiter the pattern grayscale image, the thicker the color in the three-dimensional model. A three-dimensional model (i.e., a three-dimensional model) with a pattern structure can be generated by different depths and thicknesses.

[0048] For example, Figure 6 Based on Figure 5 The generated 3D model is obviously Figure 6 The model shown not only has a three-dimensional structure but also has Figure 5 The pattern structure shown.

[0049] In an optional embodiment, a three-dimensional model with a pattern structure is generated based on a pattern grayscale image, including: filtering out grayscale gradients in the pattern grayscale image to obtain a standard pattern grayscale image; wherein the standard pattern grayscale image records grayscale information at different pixels; and generating a three-dimensional model with a pattern structure based on the grayscale information at different pixels.

[0050] The pattern grayscale image generated by the grayscale image conversion tool may have grayscale gradients. Since the initial pattern image does not have a gradient effect corresponding to the grayscale gradient, the grayscale gradient needs to be filtered out from the pattern grayscale image to obtain a standard pattern grayscale image without grayscale gradients.

[0051] Different pixels of the standard pattern restoration image record different grayscale information, and different grayscale information represents different degrees of gray, some are lighter and some are darker.

[0052] Gray information of different grayscale levels is related to different thicknesses in the three-dimensional model. Therefore, based on the grayscale information at different pixels, a three-dimensional model (ie, a three-dimensional model) with a pattern structure can be generated.

[0053] For example, Figure 3 The texture grayscale image has a grayscale gradient from the upper left to the lower right, so it is necessary to filter out the grayscale gradient to obtain a standard pattern grayscale image, and then generate a pattern structure based on the standard pattern grayscale image. Figure 6 The three-dimensional model shown.

[0054] In an optional embodiment, a three-dimensional model with a pattern structure is generated based on grayscale information at different pixels, which speeds up the generation of the three-dimensional model and helps to subsequently increase the speed of rendering the target model.

[0055] In an optional embodiment, a three-dimensional model with a pattern structure is generated based on grayscale information at different pixels, including: determining a mapping relationship between grayscale information at different pixels and a concave-convex structure of the model, and generating a three-dimensional model with a pattern structure based on the mapping relationship.

[0056] The concave-convex structure of the model refers to the thickness of different positions of the model. Some positions are convex, while others are shallow and flat. The mapping relationship refers to the correspondence between the grayscale information and the concave-convex structure of the model. Specifically, the lighter the gray level represented by the grayscale information, the more convex the concave-convex structure of the model, and the darker the gray level represented by the grayscale information, the shallower the concave-convex structure of the model.

[0057] Based on such a mapping relationship, a stereoscopic model (ie, a three-dimensional model) having a pattern structure can be generated according to the grayscale information of the pattern grayscale image at different pixels.

[0058] For example, Figure 7 The schematic diagram of using Zbrush software (a digital sculpture and painting software) to generate a three-dimensional model with a pattern structure in an embodiment of the present disclosure is shown schematically. Figure 7 As shown, the pattern grayscale image is imported into the Zbrush software. At this time, the pattern grayscale image 710 is touched, the pattern grayscale image is used as a brush mask, and a click is made in the interface 720. At this time, the Zbrush software will generate the following based on the mapping relationship: Figure 6 The three-dimensional model with pattern structure shown.

[0059] In an optional embodiment, based on the mapping relationship, a three-dimensional model with a pattern structure can be quickly generated, thereby improving the efficiency of generating the three-dimensional model.

[0060] In an optional embodiment, after generating the three-dimensional model with the pattern structure, the method further includes: topologically converting the three-dimensional model into a low-poly model.

[0061] The currently generated three-dimensional model with a pattern structure is a high-poly model (i.e., a high-precision model). Since the high-poly model has high resolution and a large number of model details, if the high-poly model is directly used as a game asset, the energy consumption of the game will increase.

[0062] Based on this, the 3D model needs to be topologically converted into a low-poly model (i.e., a low-precision model). For example, the 3D model can be imported into 3Dmax software (a 3D rendering and production software) to topologically convert the 3D model into a low-poly model.

[0063] In an optional embodiment, the three-dimensional model is topologically transformed into a low-poly model, thereby effectively reducing the consumption of game resources by the target model subsequently rendered.

[0064] In an optional embodiment, after generating the three-dimensional model with the pattern structure, the method further includes: deleting a model portion of the three-dimensional model that meets the deletion requirement.

[0065] Among them, the generated three-dimensional model with pattern structure is as follows Figure 6 As shown, in Figure 6 In the model, the peripheral part without pattern structure is not needed (this is because the peripheral part has no pattern structure). In this case, the peripheral part without pattern structure is the part of the model that needs to be deleted. In Zbrush software, the cutting command can be used to delete the part of the model that meets the deletion requirements, and the following is obtained: Figure 8In addition, the model part that meets the deletion requirement may also be any currently unnecessary part of the three-dimensional model, and any currently unnecessary part may be a part with a pattern structure or a part without a pattern structure, which is not specifically limited in this exemplary embodiment.

[0066] In an optional embodiment, deleting a model portion in the three-dimensional model that meets the deletion requirement helps to obtain a three-dimensional model that meets the model requirement, thereby improving the accuracy of a target model subsequently rendered.

[0067] In step S130, the target material represented by the initial pattern image is determined, and based on the target material and the three-dimensional model, a target model having a material effect corresponding to the target material is rendered.

[0068] In the exemplary embodiment of the present disclosure, the target material describes the properties of the surface texture, color, reflection and transparency of the initial pattern image. After the target material is obtained, the three-dimensional model is rendered based on the target material to obtain a three-dimensional model (i.e., the target model) having a target material effect corresponding to the target material and a complex pattern structure.

[0069] In an optional embodiment, based on the target material and the three-dimensional model, a target model with material effects corresponding to the target material is rendered, including: generating a material ball corresponding to the target material; using the material ball to render a low-poly model, and rendering a target model with material effects corresponding to the target material.

[0070] The material ball refers to a tool used to simulate the target material. After the material ball is generated, the corresponding target material effect can be directly rendered in the low-poly model using the material ball to obtain a three-dimensional model (i.e., the target model) with the target material effect corresponding to the target material and a complex pattern structure.

[0071] For example, Figure 5 The initial pattern image shown has a metal material. Based on this, a material ball representing the metal material is generated, and the low-poly model is rendered using the material ball to obtain a target model with a metal surface effect and a pattern structure, such as Fig. 9 shown.

[0072] In an optional embodiment, the generated material ball can be used to not only improve the efficiency of rendering the target material, but also enhance the material effect of the target model.

[0073] In the method and device provided by the exemplary embodiments of the present disclosure, an initial pattern image is obtained, the initial pattern image is converted into a pattern grayscale image, a three-dimensional model with a pattern structure is generated based on the pattern grayscale image, a target material represented by the initial pattern image is determined, and based on the target material and the three-dimensional model, a target model with a material effect corresponding to the target material is rendered. On the one hand, the generation method based on the pattern grayscale image speeds up the speed of generating the three-dimensional model with a pattern structure; on the other hand, after having the initial pattern image, a target model with material effects and a complex pattern structure can be rendered, which reduces the complexity of the rendering process, shortens the rendering cycle and the rendering cost; on another hand, if a new target model needs to be rendered later, it is only necessary to change the initial pattern image, which is convenient for adjusting the rendering result.

[0074] In addition, in an exemplary embodiment of the present disclosure, a model rendering device is also provided.
