CSG Code

Hi all,

Completed a working version of my CSG code using BSP as its base, and it comes 
in at a very compact 400 lines of code in my little testing program ( a tenth 
the size of the BREP implementation ), and its very quick so quick I tried 
timing it and the two cubes CSG I was using for a basis didn't even register 
a time above 0.0. Its only a proof of the fact that it works, and not that 
sophisticated but I feel confident in using this as a basis for KPOV.

Now comes the part of intergrating it into KPOV. This is quite a big task 
since lines are no longer good enough, and all the objects will have to be 
converted too using polygons ( Obviously excluding lights and cameras, and 
other none solid objects ). I'm willing to do this.

Though it has occured to me since I'm converting them anyway, how about we 
take advantage of this, I've been think of a global detail level for a while 
now. Some one mentioned it when I did the Heightfield display, but also 
generating the sphere sweep, with its values for detail as well. I was 
wondering what people would think of a global detail level for all object 
( well most, it wouldn't apply to cubes for instance, only onjects with 
rounded surfaces ), and what would be the preferred way to achieve this. I 
thinking coding wise, where would the objects get the value for detail from. 
perhaps a parameter to createViewStructure?
