Abstract
A machine is configured to perform data compression or data decompression with respect to visual elements, such as two-dimensional pixels of an image or three-dimensional voxels of a hologram. The machine accesses a set of visual elements and performs compression on the set by generating a bounded volume hierarchy of nodes. After the bounded volume hierarchy has been generated, with or without modification, the machine provides a compressed version of the set by providing at least a portion of the bounded volume hierarchy. The same machine or another machine accesses a compressed first representation of the set by accessing at least part of the bounded volume hierarchy. The machine may perform partial decompression of the first representation by generating a second representation of the set, based on only a portion of the bounded volume hierarchy. The machine then causes rendering and display of the second representation.
