Google's Chrome Media team recently announced a new open source project for 3D graphics, called "Draco". Perhaps some people are not familiar with the situation, you know Google has been an open source community, but an important contributor.

Draco is a library for compressing and decompressing 3D geometric meshes and point clouds. In other words, it significantly reduces the size of the 3D graphics file, and at the same time does not seriously affect the visual effect for the 3D graphics viewer. It also aims to improve the compression and transmission of 3D graphics.

"Draco was designed and developed to improve compression efficiency and speed," explains Jamieson Brettle and Frank Galligan, of Google Chrome Media team, in explaining Draco. The code supports compression points, join information, texture coordinates, color information, normal quantities, and any other general properties related to geometry. With Draco, applications that use 3D graphics can be much smaller without affecting visual fidelity. For users, this means that applications are now faster to download, faster 3D graphics loaded in the browser, and now only a small amount of bandwidth can be transmitted virtual reality and augmented reality, and can be quickly presented, The picture is extremely realistic. & Rdquo;

Draco is released as a C ++ source code that can be used to compress 3D graphics, and has also released C ++ and Javascript decoders for processing encoded data.
