You probably want a volume renderer that can do a Maximum Intensity
Projection ( MIP ).

vtkVolumeMapper
http://www.vtk.org/doc/nightly/html/classvtkVolumeMapper.html defines
SetBlendModeToMaximumIntensity so any of it's children should be able to
do what you want.

I've only used vtkFixedPointVolumeRayCastMapper
http://www.vtk.org/doc/nightly/html/classvtkFixedPointVolumeRayCastMapper.html
and I know that works.
