some help for (new) users :

I made a simple macro to create rounded boxes, so you dont't have to fool
around with slow superellipsoids. My RoundedBox renders in 1/3 (!) of the
time of a superellipsoid. There are some drawbacks, but it might be usefull.

The source can be found at p.b.s-f.

have a look at "shapes.inc"

especially
Round_Box_Union(PtA, PtB, EdgeRadius),
Round_Box_Merge(PtA, PtB, EdgeRadius) and
Round_Box(PtA, PtB, EdgeRadius, UseMerge)

naa, i think a rounded box macro is the second or third step in
understanding povray. the first being a checker plane with reflecting
spheres post in p.b.i.
