Abstract
A workflow for 3D content authoring, delivery, and rendering is facilitated based on pre-authored image projections to obtain improvements in authoring efficiency. Additionally, a content delivery platform centered on such pre-authored image projections provides a mechanism for significantly improving streaming efficiency for 3D worlds. Multiple images encode primary surface detail of 3D worlds in real-time applications. Examples of such projections include images that can be as rich as film frames, feature animation frames, high end digital renders, concept paintings, or any suitable combination thereof. An algorithm for improved image projection camera path trajectories, sampling selection, and blending may be implemented by various systems and methods to facilitate smooth transitions during movements of a player within a game set in the 3D space. In addition, a back-projection technique may be implemented by various systems and methods to propagate revisions of one or more projections.
