<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>Triangulating only cells of type VTK_CONVEX_POINT_SET is actually more difficult than it sounds. All non-triangular faces will be split into triangles. If there is any neighbor cells that share these faces, they will also have to be split in some way to keep the interfaces consistent. The splitting can then easily propagate to the neighbors’ neighbors and so on.<BR>

You probably have some sort of polyhedra that is getting converted to<BR>
VTK_CONVEX_POINT_SET.<BR>
