Abstract: Techniques for generating an arbitrary ensemble view from existing views of a plurality of scenes are disclosed. In some embodiments, for each of a plurality of scenes, each of a corresponding set of one or more views is normalized to a desired perspective if its existing perspective is different than the desired perspective. An ensemble view comprising the plurality of scenes that has the desired perspective is generated at least in part using pixels from views of the scenes having the desired perspective including the normalized views.

Abstract: Techniques for generating an arbitrary view from a plurality of other existing views are disclosed. In some embodiments, arbitrary view generation includes retrieving a first image having a first perspective and a second image having a second perspective, transforming each of the first image and the second image into a third perspective; and generating a third image having the third perspective by combining at least some of the pixels from the transformed first image and at least some of the pixels from the transformed second image.

Abstract: Improved techniques for generating video content are disclosed. In some embodiments, a frame is first rendered using a first rendering option. It is then determined whether the frame is an independent frame (I-frame) or a predictive frame (P-frame). In the event that the frame is an I-frame, the frame is rendered using a second rendering option. In the event that the frame is a P-frame, the frame as rendered by the first rendering option and a previous frame as rendered by the first rendering option are used to determine prediction error. The first rendering option comprises a lower computational complexity than the second rendering option.

Abstract: Adaptive sampling of pixels is disclosed. In some embodiments, an initial rendering of a scene that determines texture at each portion of the scene is generated, and a ray traced rendering of the scene is generated by tracing an initial sample of rays. The following steps are iterated until all portions of the ray traced rendering satisfy a noise threshold: subtract the initial rendering of the scene from the ray traced rendering of the scene to determine a measure of noise at each portion of the ray traced rendering and trace another sample of rays in the ray traced rendering for each portion of the ray traced rendering that does not satisfy the noise threshold. The completed ray traced rendering is outputted. Different portions of the completed ray traced rendering are sampled with different numbers of samples of rays.
