Referring to fig. 3, fig. 3 is a schematic view of an original vegetation model according to an embodiment of the disclosure. In the embodiment of the invention, the vegetation object required by the game scene can be created, designed and edited through three-dimensional modeling software, then the created original vegetation model is imported into the game for rendering, a corresponding game scene is generated, and the game scene is displayed for the user. Specifically, the designer can create an original vegetation model of the vegetation object in the three-dimensional modeling software, so that the game engine can acquire the original vegetation model from the three-dimensional modeling software.
Illustratively, the original vegetation model may be created based on 3d Max, Maya, etc. three-dimensional modeling software, and optionally, at least one virtual vegetation a may be included in the created original vegetation model, which may include, but is not limited to: the virtual vegetation a in the embodiment of the present disclosure is illustrated by taking a crown tree as an example, and of course, the application does not limit a specific engine type and a software type, and can be flexibly selected according to an actual application scenario.
Illustratively, in modeling the original vegetation model, the polygon patches a1 need to be separated from each other. Specifically, a break is required between the UV coordinates of each polygon patch, and the UV coordinates of each polygon patch fill the UV space (0-1). In addition, the directions of the UV coordinates of the plurality of polygonal patches change irregularly, that is, the directions of the UV coordinates of the plurality of polygonal patches are disturbed as much as possible.
In the embodiment of the present disclosure, in order to achieve a better rendering effect, the original polygon patch a1 is a quadrilateral patch. It is understood that in other embodiments, the original polygon patch may also be a triangle patch or other polygon patches, which is not limited herein.

Shaders mainly include a Vertex Shader (Vertex Shader) and a Pixel Shader (Pixel Shader). The vertex shader is mainly responsible for calculating the geometric relationship of the vertices, and the pixel shader is mainly responsible for calculating the color of the slice source.

When the rotation processing is performed on each of the plurality of original polygon patches, the rotation is performed based on the position of the virtual camera.
S103, obtaining a target vegetation model based on the plurality of target polygon patches, wherein each target polygon patch of the target vegetation model faces a virtual camera, and at least part of adjacent target polygon patches are crossed.
Referring to fig. 4, fig. 4 is a schematic view of a target vegetation model according to an embodiment of the disclosure. It can be understood that after the original polygon patches are respectively amplified and rotated, a target polygon patch B1 can be obtained, and a target vegetation model B can be obtained based on the target polygon patches B1. Each target polygon patch faces the virtual camera, which means that an included angle between a lens facing direction of the virtual camera and a normal of each target polygon patch is smaller than a preset angle, and when the included angle between the lens facing direction of the virtual camera and the normal of the target polygon patch is 0 degree, the lens facing direction of the virtual camera is perpendicular to the target polygon patch.
In the embodiment of the present disclosure, the lens orientation of the virtual camera refers to a direction of a center line of a 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 plurality of polygonal patches may be obtained first, then matrix transformation processing is performed on the original UV coordinates to obtain vertex offset information, and then, in a model local space, the vertex offset information and the original vertex coordinate information of the original vegetation model are added to obtain the target vegetation model.
Specifically, the process of obtaining the vertex offset information may include the following steps (1) to (4):
(1) converting an original UV coordinate (two-dimensional data) into three-dimensional data to obtain first target data;
(2) taking the first target data as coordinate information in a world space, and converting the first target data into an observation space to obtain second target data;
(3) taking the second target data as coordinate information in the local space, and converting the second target data into a world space to obtain third target data;
(4) and carrying out normalization processing on the third target data to obtain the vertex deviation information.
And S104, rendering the target vegetation model to generate the vegetation object.
Referring to fig. 5, fig. 5 is a schematic view of a generated vegetation object according to an embodiment of the present disclosure, as shown in fig. 3, after a target vegetation model is obtained, the target vegetation model may be rendered, and a vegetation object C is generated.
In some embodiments, in the process of rendering the target vegetation model, pixels can be removed, for example, the pixels can be removed according to Alpha information when textures are rendered, so that the rendered vegetation object C has a hollow effect, and the reality of the vegetation rendering effect is further improved.
In the embodiment of the disclosure, the original polygon patches are respectively amplified and rotated, so that each obtained target polygon patch faces towards the virtual camera, at least part of the obtained target polygon patches are adjacent to each other, and the target polygon patches are crossed, and further the utilization rate of the model vertex can be improved, so that under the same vertex calculation amount, the final vegetation effect can be more dense, or under the vegetation effect with the same density, the overhead of the vertex can be less, that is, the rendering efficiency can be improved, and meanwhile, the rendering effect of the vegetation is improved.
The above step S102 will be described in detail with reference to the specific embodiment.
In some embodiments, referring to fig. 6, regarding step S102, when the original polygon patches are respectively enlarged and rotated to obtain a target polygon patch, the method may include the following steps S1021 to S1022:
and S1021, amplifying the original polygon patch.
S1022, based on the original orientation angle and the adjustment value of the original polygon facet, performing rotation processing on the amplified original polygon facet to obtain the target polygon facet; the multiple target polygon patches are intersected with each other.
For example, an original polygon facet may be first amplified, and then, based on an original orientation angle and an adjustment value of the original polygon facet, the amplified original polygon facet may be rotated to obtain a target polygon facet, so that the plurality of target polygon facets are intersected with each other.
The original orientation angle of the original polygon patch refers to an included angle between a normal of the original polygon patch and the orientation of the virtual camera lens. The adjustment value may also be referred to as a noise value, which may be a randomly generated random number or a random number generated based on the original orientation angle of the original polygon patch, so that the rotated target polygon patches all face the virtual camera, but the orientation angles are not exactly the same, thereby achieving the effect of disordering and interleaving the leaves and improving the rendering authenticity.
Referring to fig. 7, fig. 7 is a flowchart of another vegetation rendering method according to the embodiment of the present disclosure. The vegetation rendering method comprises the following steps S201-S207:

This step is similar to the step S101, and is not described herein again.
And S202, performing coordinate conversion on the original UV coordinates of the original polygon patches.
Illustratively, since the original UV coordinate range is (0, 1), in order to achieve scaling according to the center of the original polygon patch so as to make the effect of the intersection of the multiple target polygon patches more uniform, the original UV coordinates of the multiple original polygon patches need to be subjected to coordinate transformation, and the original UV coordinate range is transformed from (0, 1) to (-1, 1), so that the UV coordinate at the center of the polygon patch is (0, 0).
And S203, respectively amplifying and rotating the original polygon patches after the coordinate conversion.
This step is similar to the step S102, and is not described herein again.
And S204, obtaining a target vegetation model based on the plurality of target polygon patches, wherein each target polygon patch of the target vegetation model faces the virtual camera, and at least part of adjacent target polygon patches are crossed.
This step is similar to the step S103, and is not described herein again.
S205, determining the target view angle orientation of the virtual camera lens under the condition that a trigger event aiming at the virtual camera lens adjustment is detected.
It is understood that in a game scene, the visual angle orientation of the virtual camera can be changed according to the control of the player, and when the visual angle orientation of the virtual camera is changed, the presented content is different. Thus, in case a triggering event for the virtual camera lens adjustment is detected, the target view angle orientation of the virtual camera lens needs to be determined.
And S206, respectively rotating the plurality of target polygon patches according to the target view angles and the directions, so that each target polygon patch faces the virtual camera.
When the visual angle position of the virtual camera changes, if the orientation of a plurality of target polygon patches is not adjusted, the rendered vegetation object is distorted, so that the target polygon patches are rotated respectively to make each oriented towards the virtual camera according to the target visual angle position, so that the rendering effect of the rendered vegetation object is not changed after the visual angle position of the camera lens is changed, and the visual experience of a player is improved.
And S207, rendering the target vegetation model to generate the vegetation object.
This step is similar to the step S104, and is not described herein again.
It can be understood that there may be a wind blowing effect in a game scene, and if there is a wind blowing, the vegetation object does not exhibit the wind blowing effect, and will affect the experience of the player, so in some embodiments, in order to improve the real experience of the player, referring to fig. 8, before rendering the target vegetation model, the vegetation rendering method further includes the following steps S208 to S209:
and S208, acquiring the blowing attribute information in the target scene.
And S209, dynamically processing the UV coordinates of the original polygon patches based on the blowing attribute information.
In the embodiment of the present disclosure, the UV coordinates of the plurality of original polygonal patches are dynamically processed, and then the amplification and rotation processes are performed. It can be understood that, in other embodiments, the original polygon patch may be first enlarged and rotated, and then dynamically processed, that is, as long as the blowing effect can be finally achieved, and the specific implementation process is not limited herein.
The blowing attribute information includes, but is not limited to, blowing size information, blowing direction information, and the like.
In some embodiments, the dynamic processing of the original UV coordinates of the plurality of original polygon patches may specifically include the following (a) to (d):
(a) rotating the original UV coordinate to obtain a rotated UV coordinate;
(b) converting the original vegetation model from a local space to the world space to obtain target vertex coordinates of a vertex of the original vegetation model in the world space;
(c) generating noise texture based on the engine built-in function changing along with time and the target vertex coordinates;
(d) and fusing (such as lerp mixing) the original UV coordinate and the rotated UV coordinate by adopting the noise texture to obtain a target UV coordinate.
In the present embodiment, the rotation processing of the original UV coordinates means that the original UV coordinates of each polygon patch are randomly rotated by different angles such as 90 degrees, 180 degrees, and 270 degrees. After the target UV coordinate is obtained, the target UV coordinate may be subjected to subsequent corresponding steps, such as coordinate conversion, amplification, rotation, and the like.
It will be understood by those skilled in the art that in the method of the present invention, the order of writing the steps does not imply a strict order of execution and any limitations on the implementation, and the specific order of execution of the steps should be determined by their function and possible inherent logic.
