[osg-users] Node with different projection/view matrix fixed pipeline

[Catalin]

Hi Robert,

I have an old code, as you know. Some objects are rendered with OpenGL, but
before that the ViewMatrix is set to identity, as the the objects are
having their position computed as follow:

ObjectPositionView = ViewMatrix * ObjectPosition + 2D Move Vector(x,y) in
view space

ObjectPositionView already contains the ViewMatrix, so I am feeding it
directly to the Open GL.

Those object are some billboards but with the option to be moved in the
view space, like a 2D move.

If I give directly the ObjectPosition to OSG, it works fine with billboards
but I don't know how to incorporated the 2D Move Vector, that vector is in
the view space.
