Vertex compression for billboards #419

Closed pjcozzi closed 10 years ago

pjcozzi commented 11 years ago

Lots of good ideas here if/when we decide to compress billboard vertices: http://www.humus.name/Articles/Persson_CreatingVastGameWorlds.pdf

It also has good ideas for inverting matrices with Gauss-Jordan elimination.
