Francesco,
From the documentation:
vtkConvexPointSet is a concrete implementation that represents a *3D*
cell defined by a convex set of points.
So for a 2D cell you are better of using:
http://www.vtk.org/doc/nightly/html/classvtkPolygon.html
[vtkPolygon is a concrete implementation of vtkCell to represent a 2D
n-sided polygon. The polygons cannot have any internal holes, and cannot
self-intersect. Define the polygon with n-points ordered in the
clockwise direction; do not repeat the last point.]
HTH
Mathieu
Ps: If you are doing anything heavily based on those cells I suggest you
create your own 2D cell that handle octahedral cell.
