The result is an FBO without multisampling whose buffers are filled
by
combining the multiple samples from the multisample FBO together.
Ok so the FBO multisampling is supported but not directly as it said
on

I tried your suggestion, osgconv -o GoogleMode [model 1.flt] [model 2
.dae].
Didn't work. All osg did was post up the list of all the available
options
OSG_DATABASE_PAGER_PRIORITY mode etc etc etc. Is it safe to assume
that
GoogleMode is not

Yes I am already using the osgUtil::PolytopeIntersector to work out
whether
the object is inside the FOV. However I am finding that the list of
intersections includes my node of interest regardless of whether it
has been
culled or not

How did you test that setting both to 4 didn't work?
This is how I tested it:
...
// code in MyCameraDrawCallback
glReadBuffer(GL_COLOR_ATTACHMENT0_EXT);
float* tempbuf32Bits = NULL;
tempbuf32Bits = new float[500*500];

I should probably have used .ive file. I didn't consider such
possibility ver
carefully when I started. There is an other fellow doing exactly that
for
OpenSG, except for OpenSG use XML file format which I think is really
cumbersome.

Hi, I set the color by using a fragment shader and the 32 bits
floating point
blending seems to be working now.
I would like to use multisampling in my FBO. How can I configure that?
Is it
only by setting the method:

Hi,
That didn't either. Maybe I missing some step in the setup.
What I did was:
Ran Cygwin's setup.exe to install OpenGl, Cygwin, GCC, and several of
the
pre-reqs I unzipped the latest source (2.8.1) into
I have a multiple display system with an NVIDIA 8800 GT (driver version
181.20) that has performance problems when I use FBOs (see attached test
case, modified from osgviewer.cpp). My draw times jump from about 7
milliseconds to 14, and my GPU times jump from less than 1ms to 7ms.
The problem
directly).
I didn't think to check before, but SingleThreaded does seem to help
some (my test case's draw time goes from 14 to 9 milliseconds).
I'll give the 185.85 driver a shot.
Thanks for the help!

Hi,
I have some paged data with DDS textures, which require the
