[Mesa3d-dev] Searching for the Depth Buffer implementation

[asimov01 <mh...@ya...>]

Hi Guys,

I am trying to implement the openGL Readpixels for depth buffer in plain
c++.  I have tried to dig into openGL for this but I think this is protected
and I think its done in hardware.  I tried to look in mesa but can't seem to
track it down.  If anyone knows which file the mesa code is in please point
me in the right direction, I would really appreciate it.  I just need to see
how mesa deals with this.

I am actually also trying to find glViewPort implementation.  I have the
math that goes with it but again want to see how mesa has implemented it.

Any help will be appreciated...
