News: Fast compression for 3D graphics - Draco.

Draco is a library for compressing and decompressing 3D geometric meshes and point clouds.
With this faster using Draco’s JavaScript decoder it is intended to improve the storage and transmission of 3D graphics.
You can found the source code at github. See how fast is it:
