vtkSQ3SubdivisionFilter Class Reference

#include <vtkSQ3SubdivisionFilter.h>

List of all members.

Detailed Description

SQ3 subdivision implements the √3-subdivision implemented by Leif Kobbelt at Max-Planck Institut for Computer Graphics. The filter can handle only triangle meshes so if you have other mashes use the vtkTriangleFilter to triangulate it.

Generates a new point in the output mash.

It also ubdates the cellsVisited and cellsPoints list. The new point is added to outputPD and outputPts.

vtkCellArray *    outputPolys,
vtkCellData *    outputCD
)  [protected]
 

Subdivides each cell and generates new cells.

The methode does this by first filtering the input and then generating new points. It uses the generatePoints method.

Todo:
While stepping through all neighbours we assume there is only one neighbour per edge.
