Class SoDMBufferBackground

Shape Node

This shape node automatically tracks the viewport and resizes accordingly. It is useful for texturemapping video, movies, etc. to the background of an Inventor scene -- thus tacking advantage of hardware texturemapping, anti-aliasing, etc. for arbitrary window sizes.

Techinical Note This shape disables GL_DEPTH since it is typically rendered in the background. For this reason, the background node should be the first item rendered in a path, or it will obscure any remaining objects.
