Hi Robert,
As far as I understand, most of the stereo mode (at least quad buffer
and horizontal/vertical split) use the same camera to render left and
right eye. I did not find any flag on the camera neither on the
RenderInfo to actually know which eye is being rendered.
Did I miss something ?

Hi Gaurav,
The DrawCallback gets passed the RenderInfo which has a
getCurrentCamera() that you might be able to use.

Hi,
Is there a way to know which eye (left/right) is currently being drawn inside
osg::Camera::DrawCallback. There is the UserData field in RenderInfo, but I
don't think I can use it for my purpose without having to patch
osgUtil::SceneView.cpp - the patch being that I update UserData before drawing
each eye.
Actually, I am doing render passes with render targets for a stereo
application. So I need to switch shader inputs like textures,uniforms for each
eye just before the draw call. I figured I can use the PreDrawCallback for the
purpose because it is called inside RenderStage::draw just before the actual
rendering happens. If someone has a cleaner solution, I would be most grateful.
Thank you!
Cheers,
Gaurav
