A method for object rendering

Abstract

The embodiment of the present application discloses an object rendering method. The terminal determines the real-time rendering operation performed on the object in the three-dimensional scene; according to the real-time rendering operation, a tree structure is set for the object in the three-dimensional scene, and the nodes in the tree structure are used to record the corresponding Object information; according to the hierarchy of the tree structure, select an object in the three-dimensional scene that needs to use a target object to perform the real-time rendering operation, and perform the real-time rendering operation on the object that needs to perform the real-time rendering operation; According to the result of executing the real-time rendering operation, the target object is rendered on the graphic display interface, which simplifies the real-time rendering operation and improves rendering efficiency.

Description

technical field [0001] The present application relates to the technical field of computer graphics processing, and in particular, to an object rendering method. Background technique [0002] With the development of smart phones, real-time rendering of large-scale objects in 3D scenes on smart phones has become a research hotspot. When performing real-time rendering operations on massive objects provided by BIM (Building Information Modeling, Building Information Modeling) on ​​a smartphone, a lot of calculations are often required. In this case, the method of mesh merging is usually used to optimize the rendering performance, but in the process of mesh merging, it is necessary to use the mesh before merging to create a new mesh. The memory usage increases, resulting in the memory overflow of the mobile phone and the phenomenon of program flashback; on the other hand, after the meshes are merged, multiple objects in the original 3D scene are merged into one object. , a new ...

Problems solved by technology

In this case, grid merging is usually used to optimize rendering performance, but in the process of grid merging, a new grid needs to be created using the grid before merging. On the one hand, it will cause instantaneous The memory usage increases, which causes the mobile phone's memory to overflow, and the program crashes. On the other hand, after the grid is merged, multiple objects in the original 3D scene are merged into one object. If you perform operations such as intersection detection on the objects before the merge , a new system needs to be developed separately, which increases the workload of developers and makes the real-time rendering of large-scale objects in 3D scenes on smartphones inefficient
