A system and method for the real-time composition and presentation of a
complex, dynamic, and interactive experience by means of an efficient
declarative markup language. Using the Surface construct, authors can
embed images or full-motion video data anywhere they would use a
traditional texture map within their 3D scene. Authors can also use the
results of rendering one scene description as an image to be texture
mapped into another scene. In particular, the Surface allows the results
of any rendering application to be used as a texture within the author's
scene. This allows declarative rendering of nested scenes and rendering of
scenes having component Surfaces with decoupled rendering rates.
