Howdy:

I am considering the purchase of an Octane or two, but I am very concerned
about aliasing. I understand that the Octane does anti-aliasing of points and
lines only--no polygon anti-aliasing. Since the next OpenGL machine capable of
hardware polygon antialiasing seems to be an Onyx IR at about 4 times the
price, I am seriously considering antialiasing using the accumulation buffer
(although I have yet to verify that the accum. buffer will be available on the
Octane in the rendering mode our simulator uses).

Hence the question:
Can anyone share any hints/tips/tricks/gotchas/code-snippets/algorithms or just
plain old advice on the subject of anti-aliasing using the accumulation buffer,
or similar techniques on Max Impact/Octane level machines?

Thanks
--Mike
