Abstract: An HMD device identifies a pose of the device and identifies a subset of a plurality of camera viewpoints of a light-field based on the pose. The HMD device interpolates image data of the light-field based on the pose and the subset of the plurality of camera viewpoints to generate an interpolated view; and displays at the HMD device an image based on the interpolated view. By interpolating based on the subset of camera viewpoints, the HMD device can reduce processing overhead and improve the user experience.

Abstract: In one general aspect, a method can include combining a partition polygon and a generated texture map to form a model of a scene for rendering in three dimensions in a virtual reality space. The generating of the texture map can include projecting a Layered Depth Image sample in a partition polygon to a point in a source camera window space, projecting the point back into the partition polygon as a surface element (surfel), projecting the surfel to a surfel footprint in a target camera window space, projecting from the target camera window space to the partition polygon, sub-pixel samples included in pixels covered by the surfel footprint, projecting the sub-pixel samples from the partition polygon and into the source camera window space, and applying a color weight to each sub-pixel sample based on the location of the sample in the source camera window space.
