In actual practice, individual plant models that characterize individual plant characteristics may be constructed by modeling software.
In this embodiment, one or more plant individual models may be created, and the plant types corresponding to the created plant individual models may be the same or different.
For example, by modeling software, multiple plant individual models can be constructed that characterize a single flower; multiple plant individual models can also be constructed that characterize individual flowers and multiple plant individual models that characterize individual grasses.
Step 120, creating a virtual plant cluster based on the at least one plant individual model.
The virtual plant cluster is a population comprising one or more plant individual models, and the plant individual models in the virtual plant cluster can be distributed randomly, uniformly or in a clustered manner.
For example, a plurality of plant individual models may be laid out in a randomly dispersed manner, creating a virtual plant cluster, and the plurality of plant individual models within the virtual plant cluster may be distributed in a random manner.
In this embodiment, individual plant individual models in the virtual plant cluster can be individually controlled by individually constructing plant individual models and integrating a plurality of plant individual models into the virtual plant cluster.

For example, as shown in fig. 2, the plant individual model is tiled on a two-dimensional plane, and each point of the plant individual model has corresponding coordinates in the two-dimensional plane.
In this embodiment, for the plant individual model in the virtual plant cluster, the states such as the growth direction and the growth degree of the plant individual model are controlled according to the first UV coordinate information of the plant individual model, and are displayed in an animation form on the display interface, so that the control of the plant growth effect is realized under the conditions of less occupied resources and less calculated amount.

And a program algorithm for controlling plant leaf withering can be compiled, the falling direction, the withering degree and other states of the plant individual model leaf are controlled by taking the first UV coordinate information of the plant individual model as algorithm parameters, and the animation of plant leaf withering is displayed on a display interface. According to the animation generation method of the virtual plants, provided by the embodiment of the application, the plant individual model of the single virtual plant is constructed, the virtual plant cluster is created, the control of the plant growth effect is realized in the virtual plant cluster according to the first UV coordinate information of the plant individual model, the simulated virtual plant growth occupies less resources and has small calculation amount, and the animation state of the single plant in the plant cluster can be accurately controlled.

wherein, the value range of the growth state parameter is 0 to 1, the growth state parameter is 0 to represent that the plant does not grow, and the growth state parameter is 1 to represent that the plant grows completely.
In this embodiment, the growth state parameter of the plant individual model may be a parameter inputted by the user to regulate the growth of the plant individual model.
When a plant corresponding to a plant individual model is required to be in a complete growth state, the growth state parameter input by a user can be 1; when a plant corresponding to a plant individual model is required to be in an ungrown state, a growth state parameter input by a user can be 0.
In actual implementation, the V coordinate value of the first UV coordinate information of the plant individual model is compared with the growth state parameter, and the plant individual model is controlled to simulate the plant growth process according to the magnitude relation between the V coordinate value and the growth state parameter.
In some embodiments, controlling the growth state of the plant individual model based on the V coordinate value of the first UV coordinate information and the growth state parameter of the plant individual model may include:
discarding the first UV coordinate information at the current moment under the condition that the V coordinate value at the current moment is larger than the growth state parameter;
and under the condition that the V coordinate value at the current moment is smaller than the growth state parameter, moving the vertex of the plant individual model to a target distance in the target direction so as to close the opening at the top end of the plant individual model, wherein the target direction is the normal direction of the vertex far away from the plant individual model.
In this embodiment, the growth state parameter of the plant individual model input at the current time is smaller than the V coordinate value of the first UV coordinate information of the plant individual model, the first UV coordinate information at the current time is discarded, and drawing is not performed.
At present, the growth state parameter of the plant individual model is input to be larger than the V coordinate value of the first UV coordinate information of the plant individual model, at the moment, the tip of the plant individual model is not closed, namely the vertex of the plant individual model is positioned in the plant individual model, the vertex of the tip of the plant individual model is deviated towards the target direction, after the target distance is moved, the opening at the top end of the plant individual model is closed, and the vertex of the plant individual model is presented.
In some embodiments, the target distance is determined based on layer thickness parameters of the plant individual model.
The layer thickness parameter of the plant individual model can be a parameter which is input by a user and used for regulating the layer thickness of the plant individual model.
For example, the V coordinate value of the first UV coordinate information of the plant individual model is compared with the growth state parameter, and if the V coordinate value is larger than the current growth state parameter, the drawing is discarded.

In this embodiment, different plant individual models in the virtual plant cluster are marked by using the vertex colors, the direction of the plant individual model for swaying is determined by using the vertex colors of the plant individual models, and the vertices of the plant individual models are shifted by combining the first UV coordinate information, so that the animation effect of the plant swaying can be simulated.
In actual execution, a program algorithm for controlling the swaying of plants can be written, different plant individual models in the virtual plant cluster are distinguished through vertex colors, and the swaying animation state of the single plant in the plant cluster is accurately controlled.
In some embodiments, the next vertex position at which the plant individual model is swayed is the sum of the current vertex position of the plant individual model and a vertex offset, the vertex offset being the product of the swaying direction and the V coordinate value of the first UV coordinate information.
The current vertex position is the original vertex position of the plant individual model at the current moment, and the next vertex position is the new vertex position after the plant individual model is swayed.
In this embodiment, the vertex color of the plant individual model is used as a random number seed, the random swaying direction of the plant individual model is calculated, the V coordinate value of the first UV coordinate information is used as an offset scaling factor of the swaying direction, and the swaying direction are multiplied to obtain the vertex offset corresponding to the swaying of the plant individual model control model.
In actual implementation, the calculation formula of the swaying performed by the plant individual model may be: new vertex position = original vertex position + pan direction x offset scaling factor, where the offset scaling factor is the V-coordinate of the first UV coordinate information.
In some embodiments, after creating the virtual plant cluster, the animation generation method of the virtual plant may further include:
and outputting grids of the virtual plant clusters, wherein the grids are used for displaying at the webpage end.

In actual implementation, the growth state and the swaying state of the plant individual model can be controlled according to the first UV coordinate information and the vertex color of the plant individual model, so that the main bodies corresponding to different plant individual models in the virtual plant cluster have different states.
In some embodiments, the plant individual model further comprises second UV coordinate information, the second UV coordinate information being coordinate information characterizing a texture distribution of the plant individual model, the second UV coordinate information being used to sample the diffuse reflection map of the plant individual model.
It should be noted that, for a single plant individual model, first UV coordinate information and second UV coordinate information are acquired, the first UV coordinate information and the second UV coordinate information are both UV coordinate information characterizing texture distribution, the first UV coordinate information is used for controlling a growth state of the plant individual model, and the second UV coordinate information is used for diffuse reflection map sampling.
In the embodiment, diffuse reflection sampling is carried out on the mapping according to the second UV coordinate information of the plant individual model, so that texture drawing of the surface of the plant individual model is completed.
