Parameters
| Name | Type | Default | Range | What it does |
|---|---|---|---|---|
| az | number | 180 | 0 to 360 deg | compass direction of the moon's centre: 0 north, 90 east, 180 south |
| alt | number | 30 | -90 to 90 deg | height of the moon's centre above the horizon |
| size (Can change over time) | number | 0.52 | 0.01 to 120 deg | angular diameter: our Moon is 0.52; 20 is a Moon about 1/40 of today's distanceCan change over time |
| sunAz (Can change over time) | number | 300 | 0 to 360 deg | compass direction of the Sun, which sets the phase (the film's Sun is not known to this block)Can change over time |
| sunAlt (Can change over time) | number | 10 | -90 to 90 deg | height of the Sun above the horizon, which sets the phaseCan change over time |
| sunDistance (Can change over time) | number | 1 | 0.05 to 60 AU | the moon's distance from the Sun: sunlight falls as 1 over its square (Earth and Moon 1, Jupiter 5.2)Can change over time |
| albedo (Can change over time) | number | 0.12 | 0.04 to 0.95 | how much sunlight the ground returns on average: our Moon 0.12, Mercury 0.14, an icy moon 0.6 to 0.9Can change over time |
| tint | color | #b7afa5 | – | colour of the ground: grey-brown by default, rust for Mars-like, white for ice |
| maria | number | 0.45 | 0 to 1 | how much of the surface is dark, smooth lava plains; 0 for none |
| craters | number | 0.65 | 0 to 1 | how many craters, big basins down to small pits; 0 is smooth ground |
| craterSize | number | 1 | 0.5 to 1.5 | how big the craters are against one another: low many small, high a few large |
| relief | number | 1 | 0 to 2 | how strongly crater walls and rims catch the light; they show most near the terminator |
| rays | number | 0.4 | 0 to 1 | strength of the bright ray system around one young crater; 0 for none |
| earthshine | number | 1 | 0 to 2 | faint light on the night side from a planet in the sky: 1 is a full Earth, 0 is none |
| softness | number | 0.15 | 0 to 1 | how gradually daylight fades at the terminator: an airless world is sharp, 0.5 and up suits one with air |
| tilt | number | 0 | -90 to 90 deg | how far the moon's pole leans to the right on the sky |
| opening | number | 0 | -90 to 90 deg | how far we look over its equator: 0 side-on, 90 down on the north pole, negative from below |
| rotation | number | 0 | -30 to 30 deg/s | how fast the surface turns; 0 is a moon that keeps one face toward us |
| seed | integer | 11 | 0 to 999 | changes where the craters, plains and ray crater lie, without changing the look |
