If you want AA on O2 you'll have to do something like duplicate the
geosets you want to antialias, make them wireframe and anti-aliased.
This is effectively a second wireframe pass.
For better quality you actually want to remodel the geosets since every
edge will be in twice with this approach. You should also disable the
zbuffer for the wireframe pass.
Another approach is to draw to a large digital media pbuffer and resize
the image to a lower resolution window. O2 is a good machine for this
with hardware accelerated resize and UMA holding all image buffers but
expect considerable overhead.
Cheers,Angus.
