Hi Robert,
This very much looks like a driver bug so we'll need to contact NVidia
and get them on to. Anyone with a hotline to NVidia?
The driver devs I met at Siggraph said that sending to
[EMAIL PROTECTED]
was our best bet when we found bugs in their OpenGL implementations.
They also

Hi Robert
Hi Robert,
thanks for looking into this.
Just ran it on Core2 Duo 2GB machine, GeForce 8800GT 256MB driver
177.67, Debian Sid.
I had to add a bit more fbo's before a crash, but maybe it's cos the
machine is slower.
With some smaller (32x32) sizes I even managed a X crash and restart.
Hi Guys,
I've now got an osgmemorytest example checked into svn/trunk, it
currently supports allocating windows, pbuffers and textures/fbo for
each of the windows/pbuffers created. I get some wierd results...
The follow test run:
osgmemorytest --window --fbo 1024 1024 -g 150
Succeeds.
Hi JP et al.

Hi Alberto,
thanks for the testing, it does seem that the problem is more general
than my specific Linux setup.

Hi,
yes, it uses FBO, I confirmed using DEBUG notify level. That is part of
the reason why I'm stumped by the X errors.
Hardware supports FBO, we are running lots of other FBO algo's requiring
512MB memory without problems.

Hi J.P.,
Thats a really strange behaviour. Could it be that you ran into driver issues.
I mean maybe linux gpu drivers doesn't work well with so much fbo's hanging
around.
osgPPU doesn't use cameras. It require a camera attachment only to get the
output (RTT) texture out of the camera.
Hi J.P,
I haven't tried the example yet, but if the camera is allocating X11
resources it sounds like its using a pbuffer rather than an FBO. Are
you using FBOs? Does you hardware/drivers support FBO?
Robert.

Hi all,
a colleague of mine is trying to implement an image processing algorithm
that requires many RTT cameras (+-150).
His algorithm runs on his Windows machine, but fails under Linux (I'm
quite sad about it :) with some of the following errors:
