Re: KPOV - want to help...

Hi, ( Yes I'm still watching the list :)

Been busy with real life, but as far as CSG work I did create this 

http://www.leonscape.co.uk/linux/csgcalc/index.html

and I had started to integrate some with KPM, but I've been extremley busy, as 
Andreas said, it very complex and slow, as soon as you get to any decent 
amount of complexity things slow down dramatically.

CSG is great for ray casting but its a pain to reproduce with wireframe. 
especially with a povray type set up where anything can be re-calculated at 
any point, most of the the other 3D programs that do CSG through an editor 
make it a one time operation ( Say Truspace for example ) doing it real time 
is almost impossible.

A big recalculate button, is the only way I could think of even making this a 
possibility for now, ( Holding a separate wireframe as part of the CSG rather 
that a combination of the child objects, move the child and hit recalculate 
to get the parent to update ) or until someone could come up with something 
better :)

I really should get back to this my real work is such a grind though...
