Hello forum, I have a scene where i am animating the light position using the animation path(picked up from an example).
Now i want to implement the per-pixel lighting to a certain node in the scene. I need to end the light position as uniform variable to the vertex shader program. I think i need to retrieve the current model-view matrix and multiply it with the initial light position so that i get the current light position(as changed by the animation path) and send it to the shader Please let me know if i am thinking in the right track. How to get the OpenGL model-view matrix from the OpenSceneGraph? Thanks Sajjad
