Hi all
I'm shipping a version of OpenSceneGraph to users which has been
compiled with G++ 4.4.3. I've also compiled my app with this version of
G++.
I'm now compiling the same OpenSceneGraph source code (2.8.2-rc4) with g
++ 4.5.2. Running my g++ 4.4.3 compiled application against this library

I want to be sure that the camera position doesn't affect the data my
shader program sees when it accesses textures I'm sharing with it.

Hi everyone
I'm using GLSL shaders with OpenSceneGraph for some scientific
visualisation. I've got sample values in a n*m floating point texture,
and a colour lookup table in a 1-D texture.
I'm sticking those textures on a osg::TexturedQuadGeometry like this:

Hi all
I'm wondering if anyone could give me some advice - I'm working on a 3D
viewer application that makes use of OpenSceneGraph. At the moment I'm
loading large 2D slices of data into textures, and then using a fragment
shader to colourise them.
The slices of data are big (up to 150MB), and co
Hello
I'm using a shader to draw a texture of 32-bit floating point data. That's
working fine, but I need to pass through whether a given texel should be
visible or not.
I'm trying to create a 1-bit texture, like this:
int internalFormat = GL_RED;
int pixelFormat = GL_RED;

Hi all
Has anyone attempted to use glXBindTexImage (and friends) to bind an X11
pixmap to a texture within OpenSceneGraph? You could then display the
contents of an X window on a surface.
I don't think it would be difficult to do, just wondering if it's
already been done - best to avoid duplicati
