Forget Raycasting this does definitly not work with Java3D. As you need to trace rays through a volume and record hits inside the volume. It's just like raytracing. It is maybe possible through using PS1.4 and extrem multipass rendering. Or it might be able to do this on hardware with upcoming hardware like P10 (3Dlabs) or maybe NV30 (Nvidia) and R300 (Ati) EOF, J.D. -- Explore SRT with the help of Java3D (http://wwwvis.informatik.uni-stuttgart.de/relativity/minkowski) (http://www.antiflash.net/java3d/relativity (mirror) =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
