Detailed Description

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.

◆ GetNumberOfEdges()

int vtkConvexPointSet::GetNumberOfEdges ( )
inlineoverridevirtual

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.

Implements vtkCell.

Definition at line 149 of file vtkConvexPointSet.h.

◆ GetEdge()

Return the edge cell from the edgeId of the cell.

Implements vtkCell.

Definition at line 150 of file vtkConvexPointSet.h.

◆ GetNumberOfFaces()

int vtkConvexPointSet::GetNumberOfFaces ( )
overridevirtual

Return the number of faces in the cell.

Implements vtkCell.

◆ GetFace()

vtkCell* vtkConvexPointSet::GetFace ( int  faceId)
overridevirtual

Return the face cell from the faceId of the cell.

The returned vtkCell is an object owned by this instance, hence the return value must not be deleted by the caller.

Warning
Repeat calls to this function for different face ids will change the data stored in the internal member object whose pointer is returned by this function.
THIS METHOD IS NOT THREAD SAFE.
