Very nice.

After I saw Cass's depth peeling paper I was thinking about doing 
something like this.

My idea was to add general support for N depth buffers.  A function 
such as glActiveDepthUnitEXT(GLuint unit) would select one of the N 
buffers for subsequent glDepthFunc() and glEnable / 
Disable(GL_DEPTH_TEST) calls.  There would also have to be GLX support 
for visuals with more than one depth buffer.

Interestingly, this technique has been around for quite a while.  I 
used it on a Stardent GS2000 circa 1991 with their XFDI graphics library.

Hi every body
 
 I am a computer engineer student i am doing a MFC win32 application using mesa:
 
 i tryed 4.0.4 and latest.
 
 And i found several problems that i cant solve :/ i looked a lot in the ailing 
 lists archives and i asked there too but seems noone knows or ...
 
 anyway i would like u to helpme please , i describe here what happened:
 
 
 after several tests with my code linking with mesa libs , i was unable to get 
a 
 valid pixel format.
 
 then i choosed some Win32 simple applications from (nehe.gamedev.net - lesson 
1)
 and i replaced GL Includes&Libs for Mesa ones and i tested the code , i get 
 same problem , windows is unable to find a valid pixel format.
 
 i looked inside the mesa-glut code searching for a pixel format descriptor , i 
 found a typical PFD declaration and i tested with it ( same error ) , that 
code 
 worked fine with GL libs but just when i link with Mesa ones he is unable to 
 find it , anyway glut is able for create the window for mesa in Win32 but i 
 cant use it inside a Win32 or MFC aplication :(((((
 
  please Helpme masters , i would be very very happy if u giveme a hint or some 
 usefull information ... thx for all!!!!!!!!!!!

 i am missing something? what is that Win32 driver? it does not gets compilated 
by the compilation script   , is it needed? 
why mesa glut works and mesa lib cant giveme success wgl calls?

anyone tested succefully a mesa in win32 enviroment without glut????
