3) test object space subdivision as postprocess
	do view space subdivison on objects
	do object space subdivision using
		sah
		modified sah
		visibility based heuristics
		visibility based heuristics + sah for undersampling

check sah if implemented right!! (bounding volume!!)

4) implement full evaluation framework

5) rerun vienna tests

6) check if memory was computed right!!

7) include tree sizes in memory computation + plots

8) include cost of bvh in drc / rmem heuristics

9) check undersampling in visualization
