In one embodiment, model data sets of at least two different types of models to be rendered are obtained, respectively, where the data sets at least include: the data set is used for representing the target state of each type of the model to be rendered in the at least two different types.
The central processor creates a basic map array, a normal map array and a rendering material array when the game runs, and is used for storing corresponding data in the following step of merging the data.
After the array is created, vertex data, bone matrix data, and index data of at least two different types of models to be rendered are obtained, where the obtained data set of each model may further include the basic map, the normal map, and the like, and the obtained data set may be changed according to an actual situation, which is not limited in this embodiment of the present application.

For example, A, B two models exist, the vertex data of the model A is 1, 2 and 3, the vertex data of the model B is P, D and F, a total rendering model C is newly created, the vertex data of the model A and the vertex data of the model B are firstly put into the model C, then the vertex data in the model C are 1, 2, 3, P, D and F, index numbers are arranged on the vertex data in the model C, 3 vertex data exist in the model A, 3 is added to the ordering of the vertex data in the model B, the ordering corresponding to the vertex data in the model C is 1, 2, 3, 4, 5 and 6, and therefore, the vertices arranged at the positions 1, 2 and 3 belong to the model A, and the vertices arranged at the positions 4, 5 and 6 belong to the model B.
It should be noted that, in the process of merging data, a total rendering model may be newly created and submitted for batch rendering, or merged data may be directly submitted for batch rendering.
Therefore, according to the embodiment of the application, the corresponding index numbers are established for the vertex data, the vertex data corresponding to each model can be quickly found in the merged data, the searching times of the processor are reduced, the operation burden is reduced, and the operation speed is accelerated.
In one embodiment, the merging data comprises: the vertex data and the index data corresponding to the vertex data; after the merging the data sets of the models to obtain merged data, the method further includes: recording model serial numbers of the models in the merged data; creating a map array, storing the maps of the models in the map array, and recording the map serial numbers corresponding to the models; creating a skeleton matrix array, calculating the skeleton matrix data corresponding to each model according to the coordinates, the orientation and the scaling in a local space to obtain new skeleton matrix data, storing the new skeleton matrix data in the skeleton matrix array, and recording the skeleton serial numbers corresponding to each model; and creating a parameter array, storing the material parameters corresponding to the models in the parameter array, and recording the parameter serial numbers corresponding to the models.
Creating a map array, wherein the map array comprises a basic map array and a normal map array, putting maps of all models into the created map array, recording map sequence numbers of the map array, and corresponding map elements in the map array to corresponding models according to the map sequence numbers.
For example: the A model comprises a map 1 and a map 2, the B model comprises a map 3 and a map 4, the map 1, the map 2 and the added map array are marked as 1, the map 1 and the map 2 are maps of the A model, the map 3 and the map 4 are marked as 2, and the map 3 and the map 4 are maps of the B model.

So similarly, the fourth value is "1", and thus the pooling serial number of vertex 1 in the A model is (A,0,1, 1).
Therefore, according to the embodiment of the application, the batching serial numbers are established for the vertexes in the vertex data, the rendering data can be quickly found from the arrays by using the batching serial numbers of the vertexes after the rendering is submitted, and the models of multiple types are rendered at one time, so that the running efficiency of the animation is improved, the running load of the processor is reduced, and the user experience is improved.
