ppmforge

Generate fractals resembling clouds, planets and starry skies.

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]
