There isn't a convenience function to jump from a Matrix to a

Hi Erappa,
can you explain where your installation fails?
Usually you check out the sources, run cmake and build the solution.
After doing so, you build the INSTALL project to install the result to

Hi Flavien,
As far as I remember you can simply change the URL in your browser to
get older versions of the SDK.
Also your errors more sound like your not setting the correct fbx
libraries in the CMake. There are mt, md and some static ones so you
might have to check which one was working.
Hi Mateusz,
Take in mind that 1D textures are limited to 8192 texels, if you need more
you should use a TextureBufferObject. I've attached a simple example

necessary.
Hope it helps.

We achieved something like that by adding a view/camera to our
compositeviewer, and by having the 'target' node part of the graph of that
camera's scene. Then at each frame we calculate how we need to move the

You can pass references to shared_ptr objects. You only need to copy them
for long-term storage, which is typically not a performance critical
operation in a scene graph.

If you don't build OSG with the GL3_AVAILABLE CMake flag, then OSG
supports GL3 and GL4 functionality via a GL 2.1 context and the OpenGL
extension interface.
Selecting the GL3_AVAILABLE flag allows you to open GL3/4 contexts. This
functionality was added in the OSG 2.9.x series. To my knowledge,
