Hi Thomas,
just like the regular polyhedra in some include file coming with POV, the
main body is an intersection of planes.
I wrote a macro that is passed an array[] of points and computes the planes
that, when INTERSECTIONed result in the "convex hull" of those points ...
... or to put it more clearly: give the vertices of a ( convex, NO HOLES )
polyhedron and get back the faces as planes.
Got a few more little ideas of that kind, but because of
a) attacks of real life ( my 16 months old daughter )
b) beta testing Rune's particle system
c) thinking about quaternions ( see p.g/"julia math ...")
they will have to wait a while ...
Stay tuned !
( and, before anybody asks: for the same reasons that macro won't be
published soon, because it needs polishing before - but it WILL be
published, if anybodys's interested )
Greetings
Karl
