Abstract: In one embodiment, a computing system may determine a view position, a view direction, and a time with respect to a scene. The system may access a spatiotemporal representation of the scene generated based on (1) a monocular video including images each capturing at least a portion of the scene at a corresponding time and (2) depth values of the portion of the scene captured by each image. The system may generate an image based on the view position, the view direction, the time, and the spatiotemporal representation. A pixel value of the image corresponding to the view position may be determined based on volume densities and color values at sampling locations along the view direction and at the time in the spatiotemporal representation. The system may output the image to the display, representing the scene at the time as viewed from the view position and in the view direction.

Abstract: In one embodiment, a method includes accessing multiple 3D photos to be concurrently displayed through multiple frames positioned in a virtual space, each of the of 3D photos having an optimal viewing point in the virtual space and determining a reference point based on a head pose of a viewer within the virtual space. The method may further include adjusting each 3D photo by rotating the 3D photo so that the optimal viewing point of the 3D photo points at the reference point, translating the rotated 3D photo toward the reference point, and non-uniformly scaling the rotated and translated 3D photo based on a scaling factor determined using the reference point and a position of the frame through which the 3D photo is to be viewed. The method may further include rendering an image comprising the adjusted multiple 3D photos as seen through the multiple frames.
