I'll look at the ssgaShapes.[cxx,h] files again. I'm using the ssgaCube 
now and no issues with it at all. The library in itself is very easy to 
use :-) I'm learning openGL and 3D programming as I go so I though I 
double check before I began a pyramid class.

I was wondering (with so many plib apps out there) has anyone else 
created aditional ssga shapes? I know there is the box, sphere, 
cylider, sky and particles, but has I'm looking for other basic shapes: 
pyramid, ramp, etc.

Probably, if anyone on this mailing list had done so, they'd have contributed
the new shape to the library - so in all likelyhood, what there is there
right now is all that there is.

We'd certainly welcome new additions to the ssgAux shapes library though.

Suggestions:

If you do a pyramid class, make it so you can set the number of sides for
the regular polygon at the base.  Then you can set that number really high
and you'll have made a cone as well as a pyramid.

It would also be nice to have 'makeCapped' and 'isCapped' (as in ssgaCylinder)
to determine whether the code generates the base of the pyramid or not.
Very often, you'd like your pyramid to sit on the ground - in which case
the polygons at the base are never visible and it's a waste of time and
space to generate them.
