Re: Depth buffer option

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

I've had a couple of days off so I'm in catch up mode. Have I missed 
something? Can an application access the
depth buffer? I thought it was private to the renderer, I think the one 
in my renderer is. If it is private, there seems
very little point in having uninitialised garbage in there before you 
render. I seem to be missing the point totally.
Can someone please explain.

Roger.
