An Algorithm of 3D WARP-Based Hybrid Rendering
|
Abstract:
Geometry based rendering(GBR) is a subject of traditional computer graphics, Along with the development of computer graphics, Image based rendering(IBR) becomes an important approach. GBR and IBR have advantage and disadvantage independently. This paper gives a novel approach of geometry and image based hybrid rendering(GIBHR) aiming at the status quo of computer graphics, analyses the research contents of GIBHR, and , gives a rendering pipeline of GIBHR. GIBHR can overcome the disadvantage of GBR and IBR, which can render geometry object and scene freely like GBR, and, has a high rendering speed like IBR, by texture map, it can keep high reality also. This paper expands algorithm of 3D WARP of IBR into geometry based rendering, proves the feasibility and validity, and, gives an algorithm of hybrid rendering based 3D WARP. This algorithm can overcome pixel discrete phenomenon of 3D WARP algorithm. At last, this paper gives an experiment result of hybrid rendering algorithm, it proves that the algorithm of hybrid rendering based 3D WARP can speed the rendering of geometry models obviously, and it has the ability of space anti aliasing.
