摘要： A method includes the steps of receiving training data comprising images of an object and associated camera poses from which the images are captured, training, based on the training data, a machine-learning model to take as input a given viewpoint and synthesize an image of a virtual representation of the object viewed from the given viewpoint, generating, for each of predetermined viewpoints surrounding the virtual representation of the object, a view-dependent image of the object as viewed from that viewpoint using the trained machine-learning model, receiving, from a client device, a desired viewpoint from which to view the virtual representation of the object, selecting one or more of the predetermined viewpoints based on the desired viewpoint, and sending, to the client device, the view-dependent images associated with the selected one or more viewpoints for rendering an output image of the virtual representation of the object viewed from the desired viewpoint.

摘要： In one embodiment, a method includes the steps of receiving, from a client device, a first viewpoint from which to view a virtual object, the virtual object having a shape defined by multiple geometric primitives, identifying, relative to the first viewpoint, visible geometric primitives from multiple geometric primitives, allocating a region in a texture atlas for each of the visible geometric primitives, generating shading information for each of the visible geometric primitives, storing the shading information of each of the visible geometric primitives in a portion of the allocated region smaller than the allocated region to create a buffer around the portion of the allocated region where the shading information is stored, and sending, to the client device, the texture atlas and a list identifying the visible geometric primitives, the texture atlas being configured for rendering images of the visible geometric primitives from different viewpoints.
