Robert,
Basically, I want to render my scene data onto an image which is not an OSG
image, but has the same structure, i.e.
* 8 bits red
* 8 bits green
* 8 bits blue
The image (memory block) contains already something (see it as a background)
and thus I only want my 3D scene objects on top of it.
one approach using RTT would be:
* Attach your input image as a texture applied to a quad that an RTT
camera is looking at. (see how HUDs work if you want the texture to not
be affected by camera projection)
* Attach an osg::Image to the camera as output (see osgprerender example)
* Draw whatever you want with the camera
* Use the output osg::Image
BTW, you can create an osg::Image that points to your own data.
Can you explain which parts of my original post are unclear, such that I can
rectify this ?
Problem is that there are many ways to do what you want.
cheers

Thank you!
Cheers,
benedikt
