Generate fractals resembling clouds, planets and starry skies. More information: <https://netpbm.sourceforge.net/doc/ppmforge.html>.

  • Generate an image of a planet:
    ppmforge > path/to/image.ppm
  • Generate an image of clouds or the night sky:
    ppmforge -night|clouds > path/to/image.ppm
  • Use a custom mesh size and dimension for fractal generation and specify the dimensions of the output:
    ppmforge -mesh 512 -dimension 2.5 -xsize 1000 -ysize 1000 > path/to/image.ppm
  • Control the tilt and the angle from which the generated planet is illuminated:
    ppmforge -tilt -15 -hour 12 > path/to/image.ppm
