Ray distribution for the heuristic implicit ray selection
function on a 64x64 grid with 5 processors
Preview after 10000 of 160000 rays have been rendered
4 semitransparent iso surfaces of a sparse grid data set
of level 12 (2049^3)
Scaling quality of the implicit ray selection function
compared to the number of processors. This reflects the
actual speed divided by the theoretical maximum speed
