Abstract

The invention discloses a three-dimensional model rendering method and device, equipment and a storage medium, and belongs to the field of computer graphics. The method comprises the following steps: in an offline calculation stage, acquiring user input data; according to the user input data, performing view angle range division for a target three-dimensional model in a three-dimensional space to obtain at least two view angle regions; obtaining a triangular visible set of the target three-dimensional model in different view angle regions; constructing an index buffer region according to the triangular visible sets of the different view angle regions, wherein the index buffer region is used for storing vertex indexes of triangles in the triangle visible sets; in a real-time rendering stage, determining a target subinterval in the index buffer region according to a current view angle; and rendering the target three-dimensional model according to the triangular visible set corresponding to the target subinterval. The rendering performance of a graphic product can be optimized.

Description

technical field [0001] The present application relates to the field of computer graphics, in particular to a three-dimensional model rendering method, device, equipment and storage medium. Background technique [0002] In the graphics rendering scene, Occlusion Culling refers to canceling the 3D model when it is blocked by other parts of the scene (such as other 3D models), which makes the 3D model invisible within the field of view of the virtual camera. The 3D model is rendered. For example, there is usually an occlusion relationship between 3D models in a game scene. Using the occlusion relationship between 3D models, you can choose to exclude invisible 3D models, cancel rendering them, and only render visible 3D models, thereby The amount of rendering of each frame of the game screen is reduced to reduce the overhead of the central processing unit (Central Processing Unit, CPU) and the graphics processing unit (Graphics Processing Unit, GPU), thereby optimizing the rend...
