Printing problems on Intel

[Roger H. <rog...@mi...>]

I have been looking into the problems we are having with printing
with the Interactive Renderer on Intel. If I manually push the Hither
clipping plane forward then most, if not all of the problems go away.

Is there a difference between the Z buffer on Intel and PowerPC?
I half remember that the Z Buffer used to default to 16 bit depth,
and that we ask Quesa to use 32 bits instead. Or was the default
changed? Has OpenGL moved on to using a floating point Z buffer
on Intel? If so can we use 64 bit doubles?

Is there a call to set the Z depth? What is it called?

Roger.
