Hello Rune

Back in March i made some POV-macros 
that do matrix calculations on 3x3
matrices stored in POV-arrays.

If you have a look at these two posts:

news://news.povray.org/38CEBC39.582A511F%40online.no

(My thread "Different error messages for same POV-file")

then maybe you are able to see how to find 
the inverse of a matrix with POV-script.
(Look at the Minv macro.)

I think that I also have some newer code 
that does the same (and maybe more) if 
you are interested.


Best regards,

Tor Olav
