Delivery of projections for rendering

摘要

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.

主权项

1. A method comprising:
providing, by a server, a collection of images to a client device, each image of the collection of images depicting at least a portion of a three-dimensional (3D) space from one of multiple projection nodes along a projection path, the projection path connecting the multiple projection nodes within the 3D space, the client device being configured to render at least a portion of the 3D space from the collection of images; receiving an indication that the client device deleted an initial image, the initial image being part of an initial collection of images provided to the client device in response to receiving a request from the client device to initiate execution of a game, the initial image depicting an initial portion of the 3D space from a prior projection node along the projection path; and responsive to movement of a player position within the 3D space, providing the initial image to the client device based on receiving the indication that the client device deleted the initial image, the client device being configured to render the initial portion of the 3D space from the initial image.
