Google Open-Sources ETC2Comp: Super Fast ETC2 Texture Compression
Written by Michael Larabel in Google on 15 September 2016 at 08:49 PM EDT. 8 Comments
Google's latest open-source project is ETC2Comp and should be quite exciting for game developers and indirectly will benefit gamers too -- especially mobile gamers and those interested in VR.

ETC2Comp is a standalone compressor for textures to the ETC2 specification, which is mandated by OpenGL ES 3.0+ but also is becoming found by desktop cards/drivers too.

The common ETC2 texture compressors are notoriously slow, so Google engineers invested in developing ETC2Comp as a "blazing fast" ETC2 compressor. This standalone project works on OS X, Linux, and Windows and can also serve as a library embedded into engines/tools.The encoding performance is incredibly more faster than the common Mali compressor as one example they shared.

More details can be found via this Media post by Google's Colt McAnils. ETC2Comp can be downloaded from GitHub. The compressor is made open-source under the Apache 2.0 license.
