I’ve been experimenting with visualization of probability densities (basically, electron clouds). For the time being, I have been using a vast array of varyingly transluscent points in combination with glPointSize() to get the desired 3-D clouding effect. However, this gets very laggy very quickly. Does anyone have any suggestions on a better (and faster) way to display volumetric data in 3D? I have tried using custom fog coordinates, but for some reason glFogCoordf() is having trouble compiling for me.
(see my other post)
On the other hand, I’m not sure if glFogCoords work the way I would need them to.
Perhaps volumetric lighting? If anyone has experience with this, let me know. Thanks.
