[vtkusers] reading 3D tif images

[Suzanne Little]

Dear all,

I'm trying to read in a tiff stack -- single tiff image with a sequence 
of 2D slices. I think I should set the file dimensionality to 3 for the 
reader but that isn't working.

Is it possible to read 3D tiff files into VTK?

Below is python code I've been using for testing. I've run it using VTK 
5.0 in Enthought's Python 2.4.3 distribution. I've also written 
equivalent C++ code and run that using VTK 5.0.3 compiled in Borland C++ 
(BDS2006). The render window shows a bar (120*1.6) based on the circle 
in the first image in the stack.

I've successfully rendered the model by splitting the tiff manually into 
seperate 2D files (tiffsplit) and using SetFileName and SetFilePattern.

#some python code for testing
import vtk

#setup renderer
# --cut--

#read in the tiff stack
reader = vtk.vtkTIFFReader()
reader.SetFileDimensionality(3)
reader.SetFileName("C:\vtk\mydata\stack.tif")
reader.SetDataExtent(0,499,0,499,0,120)
reader.SetDataSpacing(1.0,1.0,1.6)

#ContourFilter -> PolyDataNormals -> PolyDataMapper -> Actor
# --cut--

#camera, add actor, render
# --cut--

Regards,
Suzanne
