Constructor & Destructor Documentation

DooSabin::DooSabin (  Mesh *  m  )

Constructor for a Doo-Sabin subdivision surface. Parameters: m  The base mesh for the surface. Definition at line 129 of file DooSabin.cpp.

Member Function Documentation

void DooSabin::compute (  int  n  )  [virtual]

Compute a certain level of subdivision. Parameters: n  The level to which to compute. Implements Subdivision. Definition at line 141 of file DooSabin.cpp. References Mesh::getMeshGroupCount(), mm_mesh, and subdivide().

virtual int DooSabin::matrix (  int *  n, double *  m )  [inline, virtual]

Compute the subdivision matrix. Empty for now. Parameters: n  The number of edges of the face on which to compute. m  On return, the matrix. Returns: The size of the matrix? who knows.. this is stupid. Implements Subdivision. Definition at line 45 of file DooSabin.h.

void DooSabin::subdivide (  int  n  )  [private]

Subdivide the mesh to the nth level. Assumes the n-1'th subdivision has already occurred. Parameters: n  The next level of subdivision to be done.
