Which brings us to the question of optimal sampling filter
for 2D signal. My theory is that the artefacts in the default
povray aa and mosaic filtered image appear because the sampling
filter is a rigid box. This produces a ringing efect. This can
be avoided by sacrificing higher frequencies and using a smooth
edged filter.
This increases noise but reduces sampling artefacts:
+am1 +a0.0 +r9 +j13.5
It's always a trade-off :(
