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 {{[-m|-mesh]}} {{512}} {{[-d|-dimension]}} {{2.5}} {{[-x|-xsize]}} {{1000}} {{[-y|-ysize]}} {{1000}} > {{path/to/image.ppm}}

Control the tilt and the angle from which the generated planet is illuminated
