This is efficient and reads like it was fast enough to lay out ! Good enough to
make us want more images like that please ! Maybe it would be worth getting
another discussion specifically about the slow orange material so that we get
the best experts views around here on how to tweak it faster or in the worse
case on what makes it so slow, maybe as a point to improve in later pov versions
?

My favourite part is the heightfield satellite.
