Java 3D Volume Rendering

Here is the program and data files for a Java3D Volume Rendering demo. The program shows several different volume rendering algorithms and the data files show how these algorithms work on medical and siesmic data.

The program and some basic data files are in VolRend.zip:

• HTTP
• FTP

Volume Rendering is an intense user of CPU and graphics resources. There are small test files in the above demo application, so try those out first.

CThead.zip
	CThead.vol	CT scan of human head, 256x256x113, 16 bit data
	CThead.vrs	CThead.vol, intensity map, initial view
MRbrain.zip
	MRbrain.vol	MR of human head with skull removed, 256x256x109, 16 bit
	MRbrain.vrs	MRbrain.vol, intensity map, initial view
	MRslice.vrs	A 3D texture mapped "slice" through MRbrain.vol
Segy.zip
	segy256.vol	Oil and Gas dataset from Segy file, 256x256x256, 8 bit
	segy.vrs	Segy Oil and Gas dataset, segy256.vol
SegySmall.zip
	segy128.vol	Smaller version of segy256.vol, 128x128x128, 8 bit
	segySmall.vrs	Smaller version of segy.vrs, segy128.vol

On Solaris, you will need an Elite3D for the larger data files. Be sure to get the latest version of OpenGL and set the environment variable AFB_IMM_TEXTURE to set the best performance (you should see the message "ogl_afb: accelerate texture in immediate mode" mixed in with the output from the program).

I'm interested in hearing how well this program runs on PC graphics cards. Please drop me a line at if you find a PC card which can run these pretty well.
