Does anybody have an idea how to make a noise generator for 360° video?
I mean noise (clouds, waves) that looks similar in all directions of the
sphere. If I use the new "perlin" source for making an equirectangular
video, there are two problems:
1. The left edge doesn't fit to the right edge.
2. There are singularities at the poles.
Sure there is a way.
just not using perlin ultra slow filter.
Can you point me to an algorithm? I don't need high speed. Even a very
slow solution with geq filter would be fine.
