a 3D cell defined by a set of convex points
vtkConvexPointSet is a concrete implementation that represents a 3D cell defined by a convex set of points. An example of such a cell is an octant (from an octree). vtkConvexPointSet uses the ordered triangulations approach (vtkOrderedTriangulator) to create triangulations guaranteed to be compatible across shared faces. This allows a general approach to processing complex, convex cell types.

A convex point set has no explicit cell edge or faces; however implicitly (after triangulation) it does. Currently the method GetNumberOfEdges() always returns 0 while the GetNumberOfFaces() returns the number of boundary triangles of the triangulation of the convex point set. The method GetNumberOfFaces() triggers a triangulation of the convex point set; repeated calls to GetFace() then return the boundary faces. (Note: GetNumberOfEdges() currently returns 0 because it is a rarely used method and hard to implement. It can be changed in the future.

A convex point set is triangulated prior to any operations on it so it is not a primary cell, it is a composite cell.
