[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. Some embodiments of the present invention are described in detail below in conjunction with the drawings. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0035] At present, in the game works with the theme of Chinese painting style, its scene production often needs to restore the traditional landscape painting, among which the mountain covered with trees is usually an indispensable element of the Chinese painting style. Especially in traditional Chinese style landscape paintings, the steep edges of the mountains are often represented by relatively dense brushstrokes, and the shades of the brushstrokes are used to express the influence of the changes in light on the trees, which is difficult to restore. In existing three-dimensional game works, the distribution of trees on the mountain can be generated by manual placement, placing the tree models one by one on the mountain, or using the object generation brush tool to manually brush the tree models onto the mountain. Whether it is placement or using the brush tool, manual editing is required, which requires a certain amount of manpower and time, resulting in low efficiency of model generation, which is not conducive to the rapid iteration of game development.

[0036] Based on this, the embodiments of the present invention provide a mountain rendering method, device and electronic device to alleviate the technical problems of low efficiency in generating mountain tree planting models and high rendering pressure in the prior art.

[0037] To facilitate understanding of this embodiment, a mountain rendering method disclosed in an embodiment of the present invention is first described in detail. Figure 1 The flowchart of a method for rendering a mountain is shown in FIG. 1 . The method can be executed by an electronic device and mainly includes the following steps S120 to S140:

[0038] S120: Based on the height information of each mountain grid of the target mountain, a plurality of tree planting inserts are generated in the mountain grid for distributing tree planting; each tree planting insert includes insert vertex normal information;

[0039] Among them, the tree planting insert is a quadrilateral plane patch. Usually, the existing tree planting insert is usually in the form of multiple quadrilateral plane inserts or a three-dimensional polygonal mesh. Under the total number of trees in the entire scene, it will cause the rendering pressure of a huge number of model faces, resulting in low rendering efficiency, which is not conducive to the rapid iteration of game development. In the embodiment of the present invention, only one quadrilateral plane insert is used to form the tree planting insert, which can greatly reduce the pressure of the rendering stage and improve the rendering efficiency.

[0040] S130: changing the vertex normal information of each tree planting patch to the vertex normal information of the corresponding mountain mesh;

[0041] The vertex normal information of the mountain mesh corresponding to the tree patch includes: the normal information of the vertex of the mountain mesh adjacent to the tree patch and with the shortest distance to the tree patch. Figure 3 .

[0042] S140: Perform illumination calculation on each tree insert using a vertex shader to generate a vertex illumination result, so as to render the tree insert and the target mountain according to the vertex illumination result to obtain the target mountain including the tree insert.

[0043] In traditional Chinese painting, trees are often represented by dense brushstrokes at the steep edge of a mountain, and sparse brushstrokes are used to represent trees at the flat part of a mountain. Therefore, the area with a larger curvature of the mountain mesh can be calculated in Houdini and used as the generation range of the tree inserts for tree insert distribution. In the embodiment of the present invention, before the above step S120, the method may further include:

[0044] S21: Obtain the curvature of each mountain grid of the target mountain;

[0045] S22: Determine a mountain grid for distributing tree planting from the mountain grids according to the curvature.

[0046] The target mountain may be a pre-acquired mountain model in the style of traditional Chinese painting, and its three-body mesh may be established in advance through three-dimensional modeling software. The established target mountain includes information of several mesh vertices.

[0047] The mesh curvature can be obtained through the Curvature function node of Houdini software.

[0048] See also Figure 2 As shown in the figure, the highlighted part indicates the area with larger curvature of the mountain mesh, that is, the convex area of ​​the mountain, which can be used as the generation range of the tree planting inserts representing the brushstrokes of Chinese painting and used to distribute the tree planting inserts; Figure 2The shaded part in the middle represents the area with smaller curvature of the mountain mesh, that is, the concave area of ​​the mountain, and no tree planting inserts are distributed. The present invention provides a method for rendering a mountain, comprising: based on the height information of each mountain mesh of the target mountain, respectively generating a number of tree planting inserts in the mountain mesh used for distributing trees; then changing the vertex normal information of the tree planting inserts to the vertex normal information of the corresponding mountain mesh; and then using the vertex shader to perform lighting calculations on each tree planting insert to generate a vertex lighting result, so as to render the tree planting inserts and the target mountain according to the vertex lighting result, and obtain the target mountain containing the tree planting inserts. The above method can alleviate the problems of low efficiency in generating mountain tree planting models and high rendering pressure, thereby improving the efficiency of model generation and facilitating rapid game development.

[0049] In one embodiment, in the above step S120, based on the height information of each mountain grid of the target mountain, the step of generating a plurality of tree planting inserts in the mountain grids for distributing tree planting may specifically include:

[0050] (1) Based on the height information of each mountain grid of the target mountain, determine the weight corresponding to each mountain grid, where the weight is proportional to the height in the height information;

[0051] (2) According to the weights corresponding to the mountain grids, the number of tree planting inserts to be generated in the corresponding mountain grids is determined;

[0052] (3) Generate a corresponding number of tree planting inserts in the mountain grid used for distributing tree planting.

[0053] As a specific example, in the above step (1), based on the height information of the target mountain, the target mountain can be divided into two or more regions, and then corresponding weights are configured for the two or more regions respectively, and then the weights corresponding to each mountain grid are determined according to the region to which each mountain grid belongs and the weight corresponding to each region.

[0054] In an embodiment of the present invention, the target mountain can be divided into two areas, namely: an upper area and a lower area, the upper area includes the range from the top plane of the target mountain to the first dividing plane; the lower area includes the range from the bottom plane of the target mountain to the first dividing plane; wherein the distance between the first dividing plane and the bottom plane of the target mountain can be three quarters of the total height of the target mountain.

[0055] In one embodiment, the method further includes: determining, from the mountain grids of the target mountain, a mountain grid that is shortest in distance to and adjacent to the target tree planting patch in the tree planting patch as the mountain grid corresponding to the target tree planting patch.

[0056] In the embodiment of the present invention, the vertex normal information of the mountain mesh corresponding to the tree planting patch includes: the vertex normal information of the mountain mesh that is shortest in distance to and adjacent to the target tree planting patch among the mountain meshes of the target mountain.

[0057] In one embodiment, after the above step S130, the method may further include: determining a model space coordinate for each tree planting insert; each model space coordinate includes an axis point of the tree planting insert.

[0058] The specific performance of this step in software operation can be to export the model generated by the above steps S21, S22 and S120, and then establish each tree planting insert as an independent level, that is, each tree planting insert has an independent axis point.

[0059] As a specific example, you can use Python scripts to process the plane surface of each tree insert into an independent Geo level in Houdini, and then export it to an independent GameObject level in Unity, thereby retaining the Pivot information (coordinate information of the origin of the model space) of each insert object. This Pivot information is used to prepare for the subsequent Billboard technology around the camera.

[0060] In one embodiment, the above method may further include: scaling each tree planting insert in the corresponding model space coordinates according to first preset parameters to generate scaled tree planting inserts; the first preset parameters include: scaling center coordinates and scaling ratio.

[0061] That is to say, in the vertex shader part of the insert object Shader, the GameObject's own scale, rotation and displacement Transform is not used. Instead, the vertex position is multiplied by the custom scale parameter in the object model space to customize the insert size, thereby achieving independent scaling of the entire insert object.

[0062] Furthermore, the method further includes: based on the coordinate information of the origin of the model space, using billboard technology to rotate each scaled tree insert toward the virtual camera, so that the tree insert will not be exposed at any angle.

[0063] The method provided in the above embodiment uses a multi-GameObject strategy in Unity to maintain the Pivot center of each tree insert, so that each tree insert Billboard Shader rotates with the camera perspective with its own independent Pivot center, thereby achieving the final effect of the tree insert being seamless at all angles.

[0064] In one embodiment, after the above step S140 uses a vertex shader to perform illumination calculation on each tree insert and generates a vertex illumination result, the method may further include: using a fragment shader to clip the tree insert to obtain a clipping result. Rendering the tree insert and the target mountain according to the vertex illumination result includes: rendering the tree insert and the target mountain according to the vertex illumination result and the clipping result.

[0065] The embodiment of the present application provides a mountain rendering method, which can alleviate the problems of low efficiency in generating mountain tree models and high rendering pressure, thereby improving the efficiency of model generation and facilitating rapid game development. In addition, the tree inserts and target mountain rendered by this method conform to the distribution law of trees on the mountain in the style of Chinese painting, can generate the distribution of vegetation inserts according to the curvature of the mountain, and are consistent with the mountain grid in terms of lighting changes. Finally, the Pivot information of each tree insert is maintained in the batch, avoiding the failure of the Billboard technology to cause the solution to go wrong.

[0066] In addition, the present application embodiment also provides a mountain rendering device, see Figure 4 As shown, the device comprises:

[0067] The tree planting patch generation module 420 is used to generate a plurality of tree planting patches in the mountain meshes used for distributing tree planting based on the height information of each mountain mesh of the target mountain; each tree planting patch includes the normal information of the vertex of the patch;

[0068] The normal information updating module 430 is used to change the vertex normal information of each tree planting patch to the vertex normal information of the corresponding mountain mesh;

[0069] The lighting calculation module 440 is used to perform lighting calculation on each tree insert using a vertex shader to generate a vertex lighting result, so as to render the tree insert and the target mountain according to the vertex lighting result to obtain the target mountain containing the tree insert.

[0070] In one embodiment, the above-mentioned device may further include: a curvature acquisition module, used to acquire the curvature of each mountain grid of the target mountain; and determine the mountain grid for distributing tree planting from the mountain grids according to the curvature.

[0073] As a specific example, the target mountain is divided into more than two areas, including: dividing the target mountain into an upper area and a lower area; the upper area includes the range from the top plane of the target mountain to the first dividing plane; the lower area includes the range from the bottom plane of the target mountain to the first dividing plane; the distance between the first dividing plane and the bottom plane of the target mountain is three quarters of the total height of the target mountain.

[0074] In one embodiment, the device further includes: a mountain grid determination module, which is used to determine, from the various mountain grids of the target mountain, a mountain grid that is shortest in distance and adjacent to the target tree planting patch in the tree planting patch as the mountain grid corresponding to the target tree planting patch. In one embodiment, the device further includes: a model space coordinate determination module, which is used to determine the model space coordinate for each tree planting patch; each model space coordinate includes the axis point of the tree planting patch.
