Research on Hybrid Rendering for Walking through Forest Scene
一种实现森林场景漫游的几何与图像混合绘制方法

Hybrid rendering is a main technology for modeling and rendering of the forest.A valid method of hybrid rendering for forest scene now widely adopted is texture mapping technology which maps tree image to rectangles perpendicular to terrain surface.However,this method can't produce a high reality scene for using only one tree image which makes the tree's appea-(rance) looks the same from any view direction.To resolve this problem,a new method is proposed in this paper: generating the images real-time for the new viewpoints by 3D Warping with the given reference tree images.This method can generate the tree image with different shape for different viewpoint,consequently improve the scene's reality.At the same time,the sampling method and the algorithm for generating new image is also described detailedly.
