Effect

Rectangular To Polar

Wrap the rectangle into polar space for circular remaps.

Wrapping a rectangle into polar space bends horizons into circles and turns straight edges into arcs. It is a favourite of tunnel visions, planetoid projections and music visuals.

Combine with its inverse unwrap when you want to edit in one space and display in another.
