Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, but not all embodiments. The components of the embodiments of the present disclosure, which are generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present disclosure provided in the accompanying drawings is not intended to limit the scope of the disclosure, as claimed, but is merely representative of selected embodiments of the disclosure. All other embodiments, which can be made by those skilled in the art based on the embodiments of this disclosure without making any inventive effort, are intended to be within the scope of this disclosure.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures.
The term "and/or" is used herein to describe only one relationship, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist together, and B exists alone. In addition, the term "at least one" herein means any one of a plurality or any combination of at least two of a plurality, for example, including at least one of A, B, C, and may mean including any one or more elements selected from the group consisting of A, B and C.

With the development of the game industry, the more games are developed for the mobile terminal based on the flexibility of the mobile terminal. Currently, when a wide vegetation effect (such as grass sea, flower sea, forest, etc.) is shown in a game, a large number of patch geometries with texture maps are used, and textures are designated on the patch geometries to simulate the vegetation effect.
In the development of game scenes, it is difficult to model and render each leaf in a polygonal manner due to the limitation of the device performance of the game client on the calculation amount of polygon vertices.

It can be understood that, after the plurality of original polygonal patches are amplified and rotated, respectively, the target polygonal patch B1 can be obtained, and the target vegetation model B can be obtained based on the plurality of target polygonal patches B1. And when the included angle between the lens orientation direction of the virtual camera and the normal line of the target polygonal surface patch is 0 degree, the lens orientation direction of the virtual camera is perpendicular to the target polygonal surface patch.
It should be noted that, in the embodiment of the present disclosure, the lens orientation of the virtual camera refers to the direction of the center line of the field angle of the virtual camera, and the preset angle may be 30 degrees, 40 degrees or other angles, which may be determined according to specific requirements, and is not limited herein.
In some specific implementation manners, the original UV coordinates of the multiple polygonal patches may be obtained first, then the matrix transformation processing is performed on the original UV coordinates to obtain vertex offset information, and then the vertex offset information and the original vertex coordinate information of the original vegetation model are added under the model local space, so that the target vegetation model may be obtained.
Specifically, the process of obtaining the vertex offset information may include the following (1) to (4):
(1) Converting the original UV coordinates (two-dimensional data) into three-dimensional data to obtain first target data;
(2) Taking the first target data as coordinate information in world space, and converting the first target data into observation space to obtain second target data;

Referring to fig. 5, fig. 5 is a schematic diagram of a generated vegetation object according to an embodiment of the disclosure, and as shown in fig. 3, after a target vegetation model is obtained, the target vegetation model may be rendered, so as to generate a vegetation object C.
In some embodiments, pixels can be removed in the process of rendering the target vegetation model, for example, pixels can be removed according to Alpha information when textures are rendered, so that the rendered vegetation object C has a hollowed-out effect, and the reality of the vegetation rendering effect is further improved.
In this disclosed embodiment, through carrying out the enlargement and the rotation respectively to a plurality of primitive polygon dough pieces for every target polygon dough piece that obtains all faces virtual camera, and at least partly is adjacent the crossing fork of target polygon dough piece, and then can improve the utilization ratio of model summit, make under the same summit calculated amount, final vegetation effect can be more dense, perhaps under the vegetation effect of same density, the overhead of summit can be less, namely, can be when improving the rendering efficiency, promoted the rendering effect of vegetation.
The above step S102 will be described in detail with reference to specific embodiments.
In some embodiments, referring to fig. 6, for the above step S102, when the plurality of original polygon patches are respectively amplified and rotated to obtain a plurality of target polygon patches, the following steps S1021 to S1022 may be included:

The original orientation angle of the original polygonal surface patch refers to an included angle between the normal line of the original polygonal surface patch and the virtual camera lens orientation. The adjustment value can also be called a noise value, and can be a random number generated randomly or a random number generated based on the original orientation angle of the original polygonal surface patch, so that the orientation angles of the rotated target polygonal surface patch are not completely the same although the target polygonal surface patch faces the virtual camera, the effect of staggered interweaving of leaves is achieved, and the rendering authenticity is improved.
Referring to fig. 7, fig. 7 is a flowchart of another vegetation rendering method according to an embodiment of the disclosure. The vegetation rendering method comprises the following steps of S201 to S207:

s208, obtaining wind attribute information in the target scene.
And S209, dynamically processing the UV coordinates of the plurality of original polygonal patches based on the wind attribute information.
In the embodiment of the disclosure, the UV coordinates of the plurality of original polygon patches are dynamically processed, and then the aforementioned enlarging and rotating processes are performed. It will be appreciated that in other embodiments, the original polygonal dough sheet may be first subjected to the enlarging and rotating process, and then subjected to the dynamic process, that is, as long as the wind blowing effect is finally achieved, and the specific implementation process is not limited herein.
The wind attribute information includes, but is not limited to, wind magnitude information, wind direction information, and the like.

(b) Converting the original vegetation model from a local space to the world space to obtain a target vertex coordinate of a vertex of the original vegetation model in the world space;
(c) Generating a noise texture based on a time-varying engine built-in function and the target vertex coordinates;
(d) And fusing (such as lerp mixing) the original UV coordinates and the rotated UV coordinates by adopting the noise ripple principle to obtain target UV coordinates.
