- getters/setters are no more in Vector3 - object hierarchies thus don't use "isDirty" - this was completely killing performance for anything that was touching a lot of Vector3 like creation of meshes and dynamic buffers - even without this, performance of hierarchies went up (a lot) - objects do not get passed renderer anymore - camera was almost also removed, but this is useful for LOD (though there may be some cleaner way to do this?) - material ids are now unified, this makes "geometry.sortFacesByMaterial" faster (thus scene init / GUI blocking is shorter) - all WebGL examples should work now (render-to-texture has weird lights and in some camera control feels different) - CanvasRender still broken, despite many efforts :( - currently only points and lines work, faces don't show up. I think this may need assistance from mrdoob.
