• 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}}
