The difference is in the rendering algorithms. Just like Rayshading
is much better than anything that dx can produce; the Phaung shading
in software rendering is much better than the shading in OpenGL.
Also, OpenGL does not support a volume rendering option (thus the
limitations you're seeing). It is possible to simulate volume
rendering by using an opacity map on the solid volumes with hardware,
but that is the best you can do.

Oooo... Pretty! But, why doesn't volume rendering work in hardware
mode? I have noticed that some pictures just look better in software
than in hardware mode (less gleam, better gradual change of hues and
colours), does this have anything to do with it?
