<DIV>I am again writing my question.Is it always preferable to triangulate vtkPolyData using vtkTriangleFilter when it is not triangulated?In the VTK book,it is recommended to use parallel make even on a single processor system.I have installed without parallel option.I have very little knowledge with MPI,But this time if I want to use parallel on a single computer what do I need to do?How to configure VTK with MPI on a single processor?Thanks</DIV> <DIV>Wei.<BR><BR><B><I>Wei Woo <weiwoo11@yahoo.com></I></B> wrote:</DIV> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid"> <DIV>When vtkPolyData is not triangulated,then should it be triangulated first.Should it make the normals more regular and consistent rather than when not triangulated?</DIV> <DIV>Looking forward to a reply.Wei.</DIV> <DIV> <HR SIZE=1> Be a PS3 game guru.<BR>Get your game face on with <A
