Abstract:
Objects can be rendered in three dimensions and viewed and manipulated in an augmented reality environment. A number of object images, a number of segmentation masks, and an object mesh structure are used by a client device to render the object in three dimensions. The object images and segmentation masks can be sequenced into frames. The object images and segmentation masks can be partitioned into patches and sequenced, or ordered, within each patch, and a keyframe can be assigned in each patch. Then, the object images and segmentation masks can be encoded into video files and sent to a client device. The client device can quickly retrieve a requested object image and segmentation mask based at least in part on identifying the keyframe in the same patch as the object image and segmentation mask.
