Ray Casting Example??

I’m looking for a ray casting example, such as source or psuedo-code in C++. I would also like to find more information about Polygon Assisted Ray Casting (PARC) that is used in the medical visualization application VolVis. I can’t seem to find but a few papers on PARC.

Does anyone know what I’m talking about??

Aehmm… No :wink:

Do you mean texture-based volume rendering using 3D textures or stacks of 2D-textured slices ?

Stacks of 2D textured slices.

You will find a lot of articles if you look for the term “texture-based volume visualization” or “… rendering”,e.g. http://www9.informatik.uni-erlangen.de/Persons/Rezk/Projects/VolRen/index.html

Ok, thanks. I’ll take a look at it.
