	There is already another thread on vtkusers:

http://public.kitware.com/pipermail/vtkusers/2004-May/073865.html


	There are examples on how to use a vtkUnstructuredGridVolumeRayCastMapper:

http://www.vtk.org/doc/nightly/html/c2_vtk_e_7.html#c2_vtk_e_vtkUnstructuredGridVolumeRayCastMapper

and tests:

http://www.vtk.org/doc/nightly/html/c2_vtk_t_14.html#c2_vtk_t_vtkUnstructuredGridVolumeRayCastMapper

	You can override the default RayCastfunction of 
vtkUnstructuredGridVolumeRayCastMapper, by using:

vtkUnstructuredGridVolumeRayCastMapper::SetRayCastFunction(vtkUnstructuredGridVolumeRayCastFunction 
* f)
http://www.vtk.org/doc/nightly/html/classvtkUnstructuredGridVolumeRayCastMapper.html#z4108_0

But keep in mind that vtkUnstructuredGridBunykRayCastFunction *is* the 
default RayCastFunction so you don't need anything fancy in your code to 
use it. Just instanciate the vtkUnstructuredGridVolumeRayCastMapper
