The texutre mapping method based on surface split by octree

This paper presents a method for texture mapping based on surface split by octree. The method builds a poly-cube boundary box with all the leafnodes intersecting with surface model of the octree and then implements mapping a texture picture to the whole surface model via texture mapping in every unit cube. The traditional two step texture mapping method causes great distortion when mapping texture picture on some complex models because the shape of the boundary box is not similar with the model but the poly-cube boundary box can be quite similar with the model. The results show that the method is more efficient to some complex surface models than two step texture mapping method.
