The exact solution will depend on your platform and how you want to
display in the 3d window. Some things to consider:
- are you wanting the 2d image to be in front of the scene in the 3d
image or part of it?
- is the 2d image a bitmap or vector drawing?

Some approaches would be:
- to convert the 2d view to a bitmap and use it as a texture in the
3d scene
- draw the 2d image directly as part of the 3d scene, adjusting the
matrix accordingly

Also is all this being done in OpenGL?

2d is not a bitmap image its dynamically reading data and updating
itself and its drawing in the window and uses opengl functions to
draw...i want this window on the top of an object in the
scenegraph...but scenegraph is using cosmo3d library and i cant write
anything as part of 3d scene using opengl functions it is using its
own cosmo3d functions to draw...

one thing is 2d is not static image but dynamically drawing on
window...

adjusting matrix i dint get this can u brief me more?

waiting 4 ur reply,
thanx

I just learnt how to do it a few weeks ago:

thanx, will try to do b...but still am a newbie working on opengl and
scenegraph hope this is not out of my scope...will get back to u
