[Imstk-developers] Draco Mesh compression

[Milef, Nicholas Boris]

I agree with Alexis. I think I've heard of this library before, and it looks cool, but I think its main use case could be distributing models for commercial applications (it's common for games for be 50 GB or more nowadays, so this could help with the download size).

Also this person makes a great point about OBJ and PLY: https://www.reddit.com/r/GraphicsProgramming/comments/5oc6x8/compression_algorithm_for_3d_graphics_googles/

I was not thinking of runtime but load time: right now meshes are really slow to read, which is a reason why Nich has been investigating Assimp.

I've tried to do cloth simulation with remote interaction using discrete cosine transforms in the past but got mixed results! Draco could be worth trying.

Might not be useful for regular applications in imstk. The only use I can see is for simulation in server-client setting for telesurgery!

Nowadays with a good SSD it is usually faster to have uncompressed data and read it from disk, than compressed data that needs to be inflated.

However it could be interesting to look into draco (came up during discussions at Kitware):

Anybody heard of it before?
