[vtkusers] Volume rendering of not equidistant planes

[Lisa Avila]

Michael,

Your only way to render that data in VTK using existing functionality is 
to convert to a vtkImageData. Only the vtkImageData volume mappers have 
the ability to render RGBA data. If you are ambitious, you can write a 
new mapper for vtkRectilinearGrid (something similar to the 2D texture 
mapper for vtkImageData). For someone knowledgeable in both VTK and 
volume rendering this would probably take a few weeks to accomplish.
