Z buffering issues

[karron at MCIRPS2.MED.NYU.EDU]

Give me a call, but you also will want to read the article
The Hidden Charms of Zbuffering
Which appeared in the Iris Universe Magazine, issue # 12.

My feeling is that sgi could use a floaing point Zbuffer, as the
dynamic range of a 16 bit z short int z buffer is to small to
be of real use in many real time applications.
