Abstract

The invention is applicable to the field of 3D technology and provides a 3D graphics rending method and system. According to the 3D graphics rending method, objects to be rendered are divided into opaque objects and transparent objects, the opaque objects are ranked according to coordinate values of the opaque objects in a z direction in a visual coordinate system from small to large in sequence, rending is performed on the opaque objects according to the rank in sequence, and rending is performed on the same pixel point corresponding to the opaque objects with different z-coordinate values for one time only. Therefore, rending in different depths is performed on the same position for one time only, updating frequency of pixels at the same position is reduced, and rending efficiency is increased.

Description

technical field [0001] The invention belongs to the field of 3D technology, and in particular relates to a 3D graphics rendering method and system. Background technique [0002] With the popularity and popularity of iphone and Android development platforms, more and more people enjoy the visual experience brought by mobile platforms. With the development of OpenGL ES, more 3D (3Dimensions) applications appear in people's lives. Compared with 2D, 3D graphics has an incomparable user experience, but the resources of the embedded platform are very limited, so it is necessary to develop 3D applications with fast response and improve the efficiency of 3D graphics rendering under tight resources. Contents of the invention [0003] The purpose of the present invention is to provide a 3D graphics rendering method to solve the problem of low efficiency of the existing 3D graphics rendering. [0004] The present invention is achieved in this way, a 3D graphics rendering method, co...
