CSG Modelling

[Leon Pennington]

Hi,

Its been a bit quiet round here, so I though I'd let everyone know what I've 
been up too, which is mainly trying to do CSG.

I finally go a brep implementation of CSG working ( not in KPov, but a simply 
little viewer program. ) and basically its rubbish for what we want. Its very 
complex, slow, and memory intesive, which is exactly what you don't want in a 
modeller for a preview. Its also 4000 lines long ( whithout comments or blank 
lines ) most of which are loops.

So after months of work, I've decided to take an axiom to heart and I'm 
throwing it away, and looking at other ways of making it work. I'm very 
determined...

Current favourite is a bsp based approach. Which looks very promising.

I now know why very few modellers do wireframe CSG, its a lot of hardwork.

I've done some more work on the Libs as well, which to be honest broke it all, 
I'll try to knock it all back into shape as soon as I can.
