file extension POT - Fractint continuous potential image
File extension POT description:
Fractint's images are usually calculated by the "level set" method, producing bands of color corresponding to regions where the calculation gives the same value. When "3D" transformed (see "3D" Images ), most images other than plasma clouds are like terraced landscapes: most of the surface is either horizontal or vertical.
