Gee, now that I've posted this I came to find quite the same topic
treated before:
http://www.paraview.org/pipermail/paraview/2009-February/011174.html
I am now looking for a way to make it possible to switch between
different mappers from within paraview. I will post how to that once I
figured out.
Best regards!

Hello!
I am working on a diploma thesis on defect analysis in cast iron. I
found ITK to be the perfect tool to manipulate my volume data. Now I
am looking for a tool for visualization. At fist, Paraview seemed to
be the perfect choice because of its VTK-Plugin capability (and thus
ITK). The bad thing is that the rendering is far too slow for my
needs. At this point I could as well store my results in a new file
and view them in another (faster) viewer. Of course this is not the
perfect way either.
Am I missing some configuration or something? What I do is loading a
raw volume (dimensions: 256x256x110), go to the display tab and choose
the following options:
Color:
Interpolate Scalars: OFF
Map Scalars: OFF
Style:
Representation: Volume
Interpolation: flat
Material: none
Which seems to be the most basic setup for rendering. When the volume
is loaded I get frames every 5 seconds. The quality is good, no
problems there, but any other generic Volume Renderer gives me 20FPS+
(using Textures). Maybe it's because the actual mapper does Ray
Casting(?). There is a field "Volume mapper" in the display tab under
"Style" but it's not enabled so I can't change anything there...
Has anybody some good advice?
Best regards,
Christian Werner
