Sorry to re-open this old discussion. I didn't know this pov4 group exist :(


Anyway, i too have worked a lot in the world of complex numbers. I
started to write a macro library that implements complex functions using
povray "function".

And so: is "cfunctions.inc" just an encapsulation of C functions ?
Does v4 include a new data type like c = <re,im> with the possibility to
access c.re and c.im ?

I'm attaching my "complex_functions.inc" just in case ... I continue to
develop it or I wait for v4 ?

last thing : where can I find "cfunctions.inc" ?
