contour of a polydata<BR><BR></FONT></DIV>
<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>I have a 3D model (a sphere located at (0,0,0) with radius of 50 pixels)
stored in a vtkPolyData and a plane (located at (0,0,0) with normal along the
z axis). Is there a class in vtk that can give me back the contour ( i.e.
circle) that is resulted by cutting the model using the plane ?</DIV>
<DIV> </DIV>
<DIV>I've tried vtkClipPolyData to clip the model using the plane but it
does not generate a contour, it just cuts the sphere and returns the remaining
piece !!!</DIV>
<DIV>There are a number of contouring classes in vtk and I am confused as to
which one I should be using !!!</DIV></BLOCKQUOTE><br/>
