OpenGL / GLSL: What is the best cloud / smoke visualization algorithm from bulk data?

Question

I would like to make 3D volume data: Density (can be displayed on the Alpha channel), Temperature (can be displayed on RGB). I am currently simulating a maximum projection of intensity, for example: rendering the densest / opaque pixel at the end. But this method loses the perception of depth.

I would like to imitate the effect, like a fire inside a smoke.

So my question is, what methods in OpenGL generate images based on available data?

Any idea is welcome.

Thanks Arman.

First, I tried a volume beam caster.
