Parameters
| Name | Type | Default | Range | What it does |
|---|---|---|---|---|
| latitude | number | 35 | -90 to 90 deg | the observer's latitude: 0 gives a hairline overhead, higher widens the arc toward the south |
| innerRadius (Can change over time) | number | 1.3 | 1.05 to 4 Earth radii | distance of the ring's inner edge from the Earth's centreCan change over time |
| outerRadius (Can change over time) | number | 2.3 | 1.1 to 8 Earth radii | distance of the ring's outer edge; wider rings make a broader arcCan change over time |
| opacity (Can change over time) | number | 0.7 | 0 to 0.99 | how much of the sunlight the ring blocks at normal incidence: 0 none, near 1 solidCan change over time |
| ringAlbedo | number | 0.5 | 0.05 to 1 | how bright the ring particles are in sunlight (ice 0.5 or more, dark rock 0.1) |
| gaps | integer | 3 | 0 to 8 | how many gaps are cut across the ring, like the Cassini division |
| ringlets | number | 0.5 | 0 to 1 | how much fine ripple the ring has across its width |
| sunAz (Can change over time) | number | 180 | 0 to 360 deg | compass direction of the Sun, which lights the ring and sets the Earth's shadow on itCan change over time |
| sunAlt (Can change over time) | number | 40 | -90 to 90 deg | height of the Sun above the horizon; below it the Earth's shadow cuts the ringCan change over time |
| tint | color | #dcd3c2 | – | colour of the ring particles |
| seed | integer | 5 | 0 to 999 | changes where the gaps and ripples lie |
