Hi,
Thanks for the quick reply guys. I am trying out what you have suggested but I
can't seem to get my 2D background camera working. I am creating an osg::Viewer
then I am creating a camera with 2D ortho projection with an identity matrix as
the view matrix, the render order as PRE_RENDER etc.
I then have a scene that looks like this:
...................../- [2D BACKGROUND] - [SUB GRAPH]
[ROOT NODE]|
.....................\- [3D CAMERA] - [SUB GRAPH]
( hope rubbish diagram makes sense :? )
My 3D camera is setup as a perspective projection and a render order of
POST_RENDER.
My background is more complex than just a textured quad and the user
interaction should move the background around which also moves the "ouptut" of
the 3D camera at the same time (because this is positioned with respect to
something on the background).
Can the main camera in the scene run as a 2D camera and if so how do I set this
up?
Also if I want the 3D camera to be a slave of the main (or 2D) camera do I keep
the 3D camera's sub graph separate (i.e. not a child of the ROOT NODE) and just
call addSlave( 3DCam, false ) so it can use its own subgraph?
Cheers,
Mike
