Abstract: Traditional Texturing by using a set of two dimensional image maps is an established and widespread practice. However, it has many limitations. Parameterizing a model in texture space is very difficult, particularly with representations such as implicit surfaces, subdivision surfaces, and very dense or detailed polygonal meshes. Based on an adaptive octree textures method, a kind of 3D volumetric texture approach is proposed which has less storage requirements to general octree textures maps. In addition, it carries on texture lookup in the GPU, which makes lookup much faster.
