Hi Bruce,
You can use the bit masks as you suggest, although typically one would
just use the left or right eye for mono.
W.r.t Present3D, there isn't any editor beyond an off the shelf
xml/text editor. You can read p3d files using the p3d plugin that is
now built as part of the core OSG. This
Hi Bruce,
Forgot to mention, doing stereo movies is identical to doing static
stereo image pairs, you just assign your image to a texture than is
assigned to two quads each with different tex coords to pick out the
correct part of the image for each eye. The only difference is that

Hi Guy,
This sounds rather odd. Going from bilinear to trilinear should not
have a significant effect on performance, as it would suggest that the
texture filtering is a bottleneck to a massive degree, something I
wouldn't expect any card made in the last decade to show.
So what is going on?
HI Guy,
The osgViewer::Viewer/CompositeViewer run the GLObjectsVisitor vistor
to compile GL objects on the first frame that the viewer runs, but if
you add scene graph elements after this then you'll need to compile
these. You can force the viewer to do another GLObjectsVisitor by
getting the

Hi Nick,
I am curious whether this slowdown is due to CPU work (scanning shader maps and
selecting used ones) or GPU work (shaders are recompiled or linked too often).
Do you have any profiling data to share ?
I do expect some performance degredation while using it vs standard
osg::program.
Hi osg-users,
I'm interested in compiling osg with 64bits support but it seems to be
difficult to find all dependencies for 64bits. So I was wondering if
someone already has a package from pre-built dependencies with Visual 2008
for 64bits ?
It could be interesting for OSG future to make

I took a look at the apply method and I think an improvement would be to do

Hi Robert, all,
I've read a post (I think started by Robert, but I cannot find the link
anymore) of some months ago that proposed a development aimed to improve the

Is there anything being done on this subject?
Thanks.

I wondered that too. They are obviously recognizing the boxcover image

I'm not really sure what PAT notes are, I've checked the OSG quick start guide

I think this was made by Metaio based in Germany. They use an in house
