COMPARISON OF TWO ACCELERATIONS FOR INTERACTIVE ANIMATION OF TREES

摘要

Thanks to the researches about modeling of trees, realistic tree models with textures can be semi-automatically created. On the other hand, the motion of trees according to the wind should be calculated to get more realistic presence in large animated forest scenes. If the number of primitives in a tree is large, per-frame dynamics calculation causes high computational costs, which prevents interactive rendering. In this paper, we propose two acceleration techniques for the speedup of tree animation and rendering. One is based on mainly using GPU, the other uses only CPU but with some LOD techniques. We also compare such two methods in several examples of trees and a forest scene.
