Beginnings of Culling

Both my laptop and my desktop seemed relatively happy with 1,000,000 triangles per frame, in several materials. And the entire world will probably come in around 750,000 triangles. So that’s great!


Not everyone has hardware from 2014 and 2015. And, anyway, for certain optical effects I need to do between 3 and 5 renders per frame. So, can’t just render the whole world every frame.
