Abstract

We present a novel texture compression scheme, called iPACKMAN, targeted for hardware implementation. In terms of image quality, it outperforms the previous de facto standard texture compression algorithms in the majority of all cases that we have tested. Our new algorithm is an extension of the PACKMAN texture compression system, and while it is a bit more complex than PACKMAN, it is still very low in terms of hardware complexity.

News:

This paper got the "Best Paper Award", and iPACKMAN is available as an optional extension in OpenGL ES 2.0. However, it is called "Ericsson Texture Compression" (ETC) there.

The exact specification on ETC can be found in the OpenGL ES 2.0 specification, pages 111-118.
