1. A method comprising: accessing, by one or more processors of a machine, a set of visual elements that each specify a corresponding value of an attribute; compressing, by one or more processors of the machine, the set of visual elements by generating a bounded volume hierarchy in which a parent node represents a subset of the visual elements, is associated with first and second child nodes, and indicates a representative value of the attribute, the first child node indicating a first offset from the representative value and the second child node indicating a second offset from the representative value, the representative value being generated based on the first and second offsets; modifying, by one or more processors of the machine, the bounded volume hierarchy by modifying the representative value based on itself and modifying the first offset based on itself; and providing, by one or more processors of the machine, a compressed representation of the set of visual elements by providing at least a portion of the modified bounded volume hierarchy.
