Abstract
Methods, devices, and systems for compressing and decompressing a stream of indices associated with graphics primitives. A group of delta values is determined based on a group of indices of the stream of indices. The group of delta values is compared to delta values in a lookup table. The group of indices is compressed based on an entry in the lookup table if the group of delta values matches all delta values in the entry, otherwise, the group of indices is compressed based on variable-length encoding.
