Abstract:
Systems, methods, and articles of manufacture for real-time rendering using compressed animated light fields are disclosed. One embodiment provides a pipeline, from offline rendering of an animated scene from sparse optimized viewpoints to real-time rendering of the scene with freedom of movement, that includes three stages: offline preparation and rendering, stream compression, and real-time decompression and reconstruction. During offline rendering, optimal placements for cameras in the scene are determined, and color and depth images are rendered using such cameras. Color and depth data is then compressed using an integrated spatial and temporal scheme permitting high performance on graphics processing units for virtual reality applications. The compressed content may be decoded and reconstructed in real-time by selecting, using heuristics, cameras that provide useful data for a viewer, selecting grid cells from those cameras that are visible to the viewer, and using a ray marching technique to reconstruct the scene.

Claim (Index 9):
The method of  claim 7 , wherein selecting the grid cells from the selected virtual cameras that are visible to the viewer includes:\n determining whether a respective frustum corresponding to each grid cell of the grid cells and obtained by cutting off a volume of a pyramid for the grid cell before and after minimum and maximum depth values, respectively, intersects with a frustum of a viewing virtual camera; and selecting cells associated with intersections between the frusta corresponding to the grid cells and the frustum of the viewing virtual camera.
