Texture compression techniques

摘要

A texture compression method, comprises:
(a) splitting an original texture having a plurality of pixels into original blocks of pixels;
for each of the original blocks of pixels:
(b) identifying a partition from a predefined set of partitions, wherein the identified partition has first and second disjoint subsets and wherein the first subset differs from the second subset in shape and;
(c) subdividing the original block of pixels into one or more subsets according to the identified partition; and
(d) independently compressing each subset to form a compressed texture block.
