Hi again. Still not able to cas the vtk array of triangles to a c++ regular int array. Also I would like to ask if anyone knows how to use the transform filter to change the projection plane in delaunay2D. What I would like to do is make two delaunay2D triangulations with different projection planes over a single set of 3D points. Many thanks

<br>1st of all, many thanks. I'm using C++ so the example cells.tcl gives me an<br>idea but doesn't help me as much as I need. Let me explain a little further.<br>What I want to do is to make two delaunay 2D triangulations in two different
<br>porjection planes to a set of 3D points which are collected from a 3d<br>scanner. The triangulation is part of a bigger application which at the end<br>is going save data as a vrml file but not just after the triangulation.
<br>Thats why I would like to obtain data from the vtk part of code as arrays of<br>points and triangles if it was possible.<br><br><br>Luca Pallozzi Lavorante wrote:<br>><br>> Godofredo,<br>> the vtkVRMLExporter class will generate a VRML file for you. Its input is
