The Polar Coordinates effect transforms your image between rectangular and circular coordinate systems, creating circular distortions or unwrapping circular images into rectangular ones.
How it works
Polar Coordinates converts between two different coordinate systems:
- Rectangular coordinates (x,y): The standard way images are displayed
- Polar coordinates (radius, angle): A system where position is defined by distance from center and angle
Use cases
- Creating circular spectrums from flat ones
- Unwrapping 360° panoramic images

Info
Positive curvature values transform from rectangular to polar (wrapping into a circle), while negative values transform from polar to rectangular (unwrapping a circle).
