Re: Depth buffer option

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

Ok, so you also need the depth buffer to be preserved between renders, 
so you need to tell
it to keep the buffer around on the previous render as well as not 
clear it on the second render.
That makes a bit more sense, though if a pixel's depth is not yon then 
my renderer expects
there to be a pointer to an triangle in a companion buffer (actually 
interleaved), so these would
have to be preserved as well. I presume a renderer can choose to not 
implement this new
feature anyway. Thanks for the clarification.

Roger.

P.S. I sent to the wrong list because I was replying to a message sent 
to the wrong list.
