It does, but watch out, because it can cause scenes, especially ones using
media with patterned density, to act differently than they used to.

My best regards for 0.5!

I found that next three lines  2345, 2346 and 2347
are unnecessary in file parse.c
In case that I miss the numbers:
 In function --Parse_Disc-- and enclosed in --#else-- and --#endif--
/* Calculate info needed for ray-disc intersections */
   VDot(Object->d, Object->center, Object->normal);
   Object->d = -Object->d;

And why:
in --Compute_Disc-- we have --Transform_Disc--
--Transform_Disc-- recalculate d.

Little feature request:
 disc{ <1,2,3>,<4,5,6>  } to be same as disc{ <1,2,3>,<4,5,6>, 1  }
Default radius is 1.0

I was try to made it, but...

Are you sure you wouldn't prefer a default radius of 0.5? That would
provide a "unit disc", with a *diameter* of 1. That seems more useful
to me.

Later,
