[vtkusers] large vtkpolydata set

[yenanqu at scs.fsu.edu]

Hi,
I have a large vtkPolydata set to read, but when I run the code ,  
always get error:
"ERROR: In /var/tmp/bach-build/BUILD/VTK/IO/vtkDataReader.cxx, line 1631
vtkPolyDataReader (0x8916a0): Error reading ascii cell data!"
the code works if I change a small ploy data set.  I know it is may be  
the memory problem for the large data, but, does anyone know how to  
solve it? thanks in advance.

here is my code:

package require vtk
package require vtkinteraction

vtkRenderer ren1
vtkRenderWindow renWin
     renWin AddRenderer ren1
vtkRenderWindowInteractor iren
     iren SetRenderWindow renWin

vtkPolyDataReader plate
     plate SetFileName "Cort_lobe_poly.vtk"
     plate SetVectorsName "mode8"
vtkWarpVector warp
     warp SetInputConnection [plate GetOutputPort]
     warp SetScaleFactor 0.5
vtkPolyDataNormals normals
     normals SetInputConnection [warp GetOutputPort]
vtkVectorDot color
     color SetInputConnection [normals GetOutputPort]


vtkDataSetMapper plateMapper
     plateMapper SetInputConnection [color GetOutputPort]
     plateMapper SetScalarRange -1 1
vtkActor plateActor
     plateActor SetMapper plateMapper

ren1 AddActor plateActor
ren1 SetBackground 1 1 1
renWin SetSize 500 500

renWin Render
