Hi Jim,

In your reply you mentioned this patch to generate isosurfaces from volumetric
data. Now that I successfully compiled povray I would like to give it a try
and render my data with it. But I am a totally beginner with povray, and I
probably need some directions. And you were talking about a patch to generate
the isosurfaces, where do I find this patch, I checked the pov homepage, but
could not find anything.

I would apreciate any help.

take care
