[vtkusers] Visualisation of a large vtk files

[ueberdrueber at warpmail.net]

Hi!

I have some problems displaying a 2-dimensional vtk file with the
dimensions 1185 x 2986 x 1. My small command line test program reads in
the data correctly (I have checked that by producing some output) but
when it comes to visualization the hard disk is getting very busy for a
while (whereas CPU is not used extensively) and then it crashes. 

I used a debugger to try to find the cause. It detects an access
violation in vtkOpenGLPolyDataMapper. The last call is
vtkOpenGLPolyDataMapper::DrawPolygons( ... ) which then seems to cause
some problem in the Windows system library nvoglnt.dll.

I tried to solve the problem by following the advices at 
http://www.vtk.org/Wiki/VTK_FAQ#How_to_handle_large_data_sets_in_VTK
but that didn't solve my problem. However, it has to be possible as
visualisation of the same file in fact works in Paraview.
I'm using VTK Version 5.0.3.

I would be glad if someone had some advice.

Regards,
Patrick
