Abstract:
Texturing 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 can be very difficult, particularly
with representations such as implicit surfaces, subdivision
surfaces, and very dense or detailed polygonal meshes. This paper
proposes the use of a new kind of texture based on an octree, which
needs no parameterization other than the surface itself, and yet has
similar storage requirements to 2D maps. In addition, it offers adaptive
detail, regular sampling over the surface, and continuity across
surface boundaries. The paper addresses texture creation, painting,
storage, processing, and rendering with octree textures.
