Rendering for 3D Animation Based on Octree

Abstract

Guofeng Qin and Nan Jiang

In order to improve capability of some traditional algorithms for 3D virtual reality animation, this article comes up with a new improved algorithm, which can improve traditional ones and is more suitable for 3-D graphic environment. There are two steps. The first step is to break down the entire 3-D scene and then setup the Octree structure. The second step is to transform the Octree onto 2-D plane, and write down nodes which are modified and then render the modified ones. Many experiments demonstrate the superiority of the algorithm. Especially, in the process of blanking, the quadrants are shown from far to near and achieve 3-D display more effectively, according to the given object and the location of view.
