Thist idea is a bit of a wild guess and could be totally off-base, but
would you be able to do something like storing the particle
locations/sizes in a kd-tree when converted for render, then as you're
marching the ray steps through it, rather than evaluating the
'density' of the volume based on a 3d texture, you evaluate the
density by looking up to find how many particles are within a given
radius of the shaded point... ?
