Hello Xunbin,

Another free option is the Visualization Toolkit (VTK) -
www.visualizationtoolkit.org  It is a C++ toolkit with bindings for tcl,
python, and java (so you can script and not have to write C++). It is a big
system and does take some time to learn, but it has many powerful volume
rendering techniques. There are about 500 example scripts (tcl) plus many
C++, python, and java examples too. These examples cover many visualization
techniques including 2D charts, surface rendering, structured and
unstructured grid rendering, and volume visualization.

If you want to try out the VTK volume rendering in a turn-key application,
try out VolView 1.2 (http://www.kitware.com/volview.htm) It is a commercial
application, but you can try it for free for 30-days. All of the rendering
capabilities in VolView come from VTK - so you can see what sort of images
you can create with VTK. Also, researchers can purchase low cost licenses
of VolView in exchange for images / data through the Research Partner
Program. If anyone wants more details, you can send me email directly.
