[vtkusers] Rendering voxel slices efficiently

[Phil Cook]

Hi,

I am trying to visualise slices of voxel data (MRI). I am using 
vtkImageDataGeometryFilter and vtkGlyph3D. For each point in the 
vtkImageDataGeometryFilter output, the glyph is a square / rectangle 
the size of one voxel. This gives the right image, but it's very slow. 
Is there a more efficient way to get this output?

Thanks


Phil
