Simply unzip "superformula.zip" and copy "superformula.8bf" to your "\Photoshop\Plug-Ins\" folder, or whichever plugin folder your host program uses. Load your program, open an image, go to the plugins menu and select the plugin.
This filter generates a wide variety of geometric shapes using the Superformula.
The Superformula, sometimes referred to as the Supershape, was discovered by Johan Gielis. It is a simple formula that can be used to generate a wide variety of geometric shapes.
Res: Resolution of the Supershape. If your line becomes dotted, increase the resolution.
Res (Multiplier): This is a multiplier for the Supershape resolution as sometimes you may need very high values.
Pos X: Specifies the horizontal placement (in percentage) of the Supershape.
Pos Y: Specifies the vertical placement (in percentage) of the Supershape.
Size A: Controls variable A, which defines partial Supershape size as well as form.
Size B: Controls variable B, which defines partial Supershape size as well as form.
m: Controls the rotational symmetry of the Supershape.
n1, n2, n3: Control various aspects of the Supershape.
n3=n2=n1: Locks n3 and n2 to n1. Unlock these to get more interesting Supershapes.
Size B=A: Locks Size B to A. Unlock these to get more interesting Supershapes.
m*10: This is a multiplier for m. When enabled, m is multiplied by 10 resulting in always closed Supershapes. Since it will also increase the rotational symmetry tenfold, you may wish to use lower values.
BG: Replaces the background with the specified background color.
BG Color: Specifies the background color.
Line Color: Specifies the line color.
LOAD/SAVE: Load and Save settings. (.INI files)
Reset: Resets all values to default state.
Realtime: Applies all effects (in realtime) on 'mouse drag' instead of on 'mouse release'.
