Hi!
I'm quite new to opengl, and I need to do some Off-screen rendering
with pbuffers.
I can't find any really simple example on the net. I'm developping
under Linux with and I'm using the glut library. Please Help me !

Alberto

P.s. http://www.ozzo.it/glxinfo.txt here you can find the glxinfo
output on the pc I'm using.

I wrote this (C++) a while ago:

  http://www.chem.pwf.cam.ac.uk/~jdh30/programming/opengl/pbuffer/index.html

of course, it's probably got code-rot by now... :-)

Thank you for your reply, I've 2 problems with your program:

1) I can't compile it as I get many errors.

2) It's written in C++ and you use direct access to glx libraries, and I
need absolutely to use GLUT.

I'm searching for instruction like:

To open a Pbuffer do:
1-....
2-....
3-....
Then to wite on a Pbuffer do
a-....
b-....
c-....

where did you get the documentation fro your program ?

Thanks

Alberto
