[vtkusers] Strange problem - All of my triangle mesh is not displayed (Bug?
)<BR><BR></DIV></FONT>
<P><FONT size=2>Hi all!</FONT> <BR><FONT size=2>I have a really strange
problem. I have about 500 000 points and I use a vtkCellArray to make a
triangle mesh that I put in a vtkPolyData object. When I render my scene the
bottom of my object is not showing. The strange thing is that if I use a
vtkLODActor instead of a normal actor, I can see the missing part of my mesh
when the whole actor is shown as a point could while rotating/zooming the
object. So I know for a fact that all the points have been inserted to the
PolyData object. But as soon as I stop interacting with the scene and
the object is rendered with triangles again, the bottom disappears. I also
tried using the vtkDecimatePro to decimate the PolyData object about 10% and
now I can see all of my triangles. Is there some kind of a limit to the number
of triangles that can be displayed or the number of points that can be used?
Can it be a hardware issue? Does anyone have the slightest idea?</FONT></P>
<P><FONT size=2>Can someone please help me shed I light on this - I have been
struggling with this problem for about a week now... :-/</FONT> <BR><FONT
size=2>By the way - I'm using vtk 4.02, MSVC++ 6.0 MFC. My graphics card is a
Geforce2 MX (latest drivers)</FONT> </P>
<P><FONT size=2>Thanks in advance!</FONT> </P>
