Well, very close. The "intervals" keyword is the number of "voxels"
that a ray passes trough.
(but it is rather a series of slices of a given distance, instead
of fixed size voxels (voxel means "volume element", as Pix-el)

Because they have computers 100 times more powerful than what we
can afford, and they are able to crank up the quality settings...

The most needed improvement for media is changing the sampling method
(or giving the choice) from monte-carlo to another, quicker (as halos)
samplig sheme.

See above...
