Hi all

Is it possible to use purely fog to create a 3-d image, or does fog only affect shapes/objects being seen through it?

I'm trying to create a 3d-visualization app of a semi-transparent brain for the lab I work at...

I've got a whole bunch of x-y-z points, at which I want fog in the area to be varying density and color. Can fog do the trick? Other ideas?

Thx
Ivan

I thing the class Fog (or 2d transparency gradient billboard(OrientedShape3D) ) is for simple object, for complicate object you have to search shapes(

if you have,find or make something interesting then will send info or link.
