Claim Text:
1. A computer-implemented method for compressing stencil values, the method comprising: selecting a first anchor for a first batch of stencil values that includes a first stencil value; selecting a second anchor for a second batch of stencil values that includes a second stencil value; computing a first offset that is included in a first plurality of offsets based on the first stencil value and the first anchor, wherein the first plurality is associated with the first batch; computing a second offset that is included in a second plurality of offsets based on the second stencil value and the second anchor, wherein the second plurality is associated with the second batch; computing an anchor delta based on the first anchor and the second anchor; and storing the first anchor, the anchor delta, the first plurality of offsets, and the second plurality of offsets in a memory as a first compressed stencil data instead of storing the first batch and the second batch in the memory as uncompressed stencil data.
