Hi Tyler,
Modern graphics cards love coarse grained chunks of static geometry,
they can churn through at millions of vertices a second without
breaking sweat.
Once you start make the scene graph more fine grained or making more

It is a little bit sad to lose the Open part of the name, why not go for

They are a little more clear that we are not stepping on the Kronos IP name

Hi,
is there a way to cast or convert from Texture2D to TextureRectangle (or the
other way round)? I don't strictly need it, but it'd help me debugging a multi

But my scene also has camera

HI Werner,
It sounds like you are trying to resolve a problem at the low level
which you have created by setting things up incorrectly and the top

So.. what you need to do is change how you are configuring things at
the top level. You don't clearly explain what task you are trying to

Hi Tim.
Texture2D and TextureRectangle are wrappers around two distinct types
of OpenGL textures, and at a C++ level are both subclassed from
osg::Texture, so there is no OpenGL level mapping that makes sense in
attempting to convert one to the other, and at the C++ level there
isn't any means for

Hello there,
I am using osgviewer in order to plot both the left- and right-eye image of a
point cloud which is stored in a '.osg' file.
The commands I use are quite simple:
Left: osgviewer --display MONITOR --screen 1 --stereo LEFT_EYE File.osg
Right: osgviewer --display MONITOR --screen 1 -
The problem that I have is that for the GBuffer in our deferred rendering
pipeline, every texture is a Texture2D. The result of the lighting step is also
a Texture2D. However, the last step, a lens simulation, is a TextureRectangle
which get's positioned on the screen and then just displayed in

What are you using the ABSOLUTE_RF Camera's for? My guess this is the

Could you explain what the ABSOLUTE_RF Camera

I just don't understand why Texture2D isn't sufficient for everything
you are doing. glTextureRectangle is deprecated, it was a temporary
workaround added to OpenGL, you shouldn't need it at all now that

So please just use Texture2D all the

The OSG has built in support for multi-view and stereo, there should

Hi Werner,
Using a ABSOLUTE_RF for a backgrouind image is a simply way of
implementing this type of feature but has it's limitations - it means
it won't work with anything other than a single window.
If you plan to have a view that can be composed of multiple

Just a heads up that I found a bug in osg::PointSprite(). The

Hi Robert,
It does not work like that on windows. Windows by default does not come with

you get errors when you select them as an option and t
