GPU (graphic processing unit) acceleration real-time three-dimensional rendering method

Abstract

The invention provides a GPU (graphic processing unit) acceleration real-time three-dimensional rendering method comprising the following steps of: respectively building a left model of a rendering scene and a right model of the rendering scene; calculating a left model view matrix of the rendering scene, a right model view matrix of the rendering scene and a projection matrix; executing vertex processing operation of the rendering scene; receiving elements transmitted by a vertex shader in a geometrical shader; rendering multiple rendering targets by utilizing a renderer; storing rendering result of each rendering target into two independent caches; and correspondingly displaying stereopair by adopting a three-dimensional recovery method according to the rendering result of each rendering target which is stored in two independent caches respectively. By applying the method provided by the invention, real-time three-dimensional rendering can be realized on a complex rendering scene, and rendering time required for carrying out three-dimensional rendering on a complex scene can be greatly shortened.

Description

technical field [0001] The invention relates to the field of computer graphics, in particular to a GPU-accelerated real-time stereoscopic rendering method. Background technique [0002] Stereo vision is an important part of 3D scene rendering. At present, there are many studies on stereo pair compression, stereo perception comfort and stereo display device enhancement, but less research on stereo rendering acceleration. Stereoscopic technology, which greatly increases immersion, involves rendering the scene twice, once for each eye, thus doubling the rendering time. [0003] The traditional stereoscopic rendering method takes a long time to render complex scenes, because for a scene with a given left viewpoint, it is necessary to recalculate the vertex attributes of the right viewpoint to obtain a scene corresponding to the right viewpoint of the left viewpoint . The long rendering time required to render complex scenes is a drawback of existing stereoscopic rendering meth...

[0003] The traditional stereoscopic rendering method takes a long time to render complex scenes. This is because for a scene with a given left viewpoint, it is necessary to recalculate the vertex attributes of the right viewpoint to obtain a scene corresponding to the right viewpoint of the left viewpoint.
