%description
Draco is a library for compressing and decompressing 3D geometric meshes and
point clouds. It is designed to reduce the complexity of transmitting 3D
content by compressing 3D source assets. Draco was created by the Google
Chrome media team to improve the graphics performance of web applications
and other contexts where bandwidth is constrained.
