	Let's assume (don't laugh) that someday I will own some kind
of machine that can do decent rendering in real time, or I optimize
the !@#$ out of some primitive ray-tracer.
	Following this assumption, does anybody know of a file format
for scene descriptions that include motion of objects/light-sources/
view-points, etc. ?
	Something based on nff, off, or qrt or some other quasi-'standard'
format would be nice. Maybe somebody's seen a commercial package that does
animation with rendering. (I haven't yet played with RenderMan, which I
suspect does something of this sort, but it seems to require compilation.)
What form is the input for something like this? I would suspect almost
like a programming language, eg:

	int i;
	for(i = 0; i < something; i ++)
		move_object(object,x,y,z+i);
	etc.

	Anyway, pointers, examples, etc. would be appreciated...
