Parallax Texture Mapping Technique Improvement Based on Bump Texture Mapping

Bump Texture Mapping is a hot research point of three-dimensional graphics technology in recent years,it is used to draw the details of the surface,and make the surface appear to have a rough sense,increase the true extent of rendering the scene.Parallax Texture Mapping is newly proposed to achieve a surface rough sense based on Bump Mapping,It is an improvement of traditional Bump Mapping for it can't be applied to real-time rendering system because of large amount of computation.This technology is not to offset the surface vertices,but to offset texture coordinates by the means of a height map,thus similar to the effect of displacement Mapping Technique.In this paper,from the adjustment of the height and the correction offset value,to improve the Texture Mapping,to make the surface more realistic after the drawing and add a not large amount of computation,to get wider range of applications.
