Current approach uses view aligned slicing to generate polygons for GL texturing such that the generated polygons are always facing the view plane. Now it is also possible to use object aligned slicing, which creates polygons by slicing the object perpendicular to whichever axis is facing the most the view plane. It is also possible to create a single slice for inspecting the volume, or for 2D rendering effects. Settings for this, along with a density multiplier setting, are to be found in a newly added "Smoke Display Settings" panel in the smoke domain properties tab.
