On-line space sculpturing for 3D shape manipulation
Proceedings 15th International Conference on Pattern Recognition. ICPR-2000
We present a new data structure, called the Multi-Sculpure to represent 3D shapes at multiple levels of detail. The input shape at high resolution is described as a mesh of triangles. A coarse approximation of this shape is provided by the convex hull of the mesh, while intermediate approximations are obtained by sculpturing the space that separates the convex hull from the mesh. A higher level of detail corresponds to a higher degree of concavity in the shape approximation.
