Coloring voxel-based objects for virtual endoscopy
Omer Shibolet, Daniel Cohen‐Or · 1998
This paper describes a method for coloring voxel-based models. The method generalizes the two-part texture mapping technique to color non-convex objects in a more natural way. The method was developed for coloring internal cavities for the application of virtual endoscopy, where the surfaces are shaped like a general cylinder in the macro-level, but with folds and bumps in the more detailed levels. Given a flat texture, the coloring method defines a mapping between the 3D surface and the texture which reflects the tensions of the points on the surface.
