Hi Paul,
did you have time to try the solution from Sergey, yet?
Otherwise I would try it myself next week, when I'm back in the office.
I've thought about it. His suggestion assumes that computeLocalToWorld will
contain only model (non-view) transformations. This is an invalid assumption if
the scene graph contains Camera nodes.
I imagine we could have logic like this:
Check the NodePath for the presence of Camera nodes.
If Camera nodes are present in the path
Get the view matrix as in existing code
else do as Sergey suggests:
Get the accumulated model transform from the NodePath
View = inverseModel * modelViewMatrix
But this appears to be quite a bit of code bulk to support a corner case usage
situation.
Given that SceneView is deprecated, and there are workarounds available for
anaglyphic stereo, it doesn't appear to me that any change is in order for
osgWorks / osgBullet.
