Techniques to facilitate compression of depth data and real-time reconstruction of high-quality light fields. A parameter space of values for a line, pairs of endpoints on different sides of the line, and a palette index for each pixel of a pixel tile of a depth image is sampled. Values for the line, the pairs of endpoints, and the palette index that minimize an error are determined and stored.

Depth codec for real-time, high-quality light field reconstruction

Systems, methods, and articles of manufacture are disclosed that enable the compression of depth data and real-time reconstruction of high-quality light fields. In one aspect, spatial compression and decompression of depth images is divided into the following stages: generating a quadtree data structure for each depth image captured by a light field probe and difference mask associated with the depth image, with each node of the quadtree approximating a corresponding portion of the depth image data using an approximating function; generating, from the quadtree for each depth image, a runtime packed form that is more lightweight and has a desired maximum error; and assembling multiple such runtime packed forms into per-probe stream(s); and decoding at runtime the assembled per-probe stream(s). Further, a block compression format is disclosed for approximating depth data by augmenting the block compression format 3DC+(BC4) with a line and two pairs of endpoints.

Presented herein are systems and methods configured to generate virtual entities representing real-world users. In some implementations, the systems and/or methods are configured to capture user appearance information with imaging devices and sensors, determines correspondence values conveying correspondences between the appearance of the user's body or user's head and individual ones of default body models and/or default head models, modifies a set of values defining a base body model and/or base head model based on determined correspondence values and sets of base values defining the default body models and/or default head models. The base body model and/or base head model may be modified to model the appearance of the body and/or head of the user.

Single shot capture to animated VR avatar

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.
