How to use ps polar coordinates? What is the function of polar coordinates in ps?

There are two options in PS polar coordinate options, namely "plane coordinate to polar coordinate" and "polar coordinate to plane coordinate". For example, a globe is covered with a layer of paper that draws a map of the world. "Polar coordinate" is what you look like when you look at the globe at the pole, and "plane coordinate" is what the paper on the surface of the globe looks like when it is laid flat. The polar coordinate option in PS is used to switch these two effects, which are given below.

1. Open ps first, and then press Ctrl+N to create a new sketchpad.

2. Find the rectangular marquee tool in the toolbar on the left.

3. Then use the rectangular marquee tool to draw a slender selection and fill it with color.

4. Start copying the layer 1, arrange it according to your own typesetting, fill the whole picture, and then merge all layers except the background.

5. On the menu bar, everyone filters → distorts → polar coordinate processing layer.

6, click on the polar coordinates, you can see that there are two effects.

7. Click OK and the effect is as follows:
