Parameters
| Name | Type | Default | Range | What it does |
|---|---|---|---|---|
| plain | number | 24 | 4 to 120 m | the plain's height above today's sea at the coast |
| tilt | number | 0.8 | 0 to 8 m/km | how fast the plain rises inland; flood basalt plains slope a few metres a kilometre |
| benches | number | 9 | 0 to 30 m | the height of each lobate flow-front scarp; the plain climbs inland in broad stairs of this height |
| ridges | number | 38 | 0 to 60 m | how tall the pressure ridges stand, where the lava crust buckled; 0 for a smooth sheet |
| ridgeSpacing | number | 2 | 1 to 4 km | the distance from one pressure ridge to the next across the flow |
| channels | integer | 3 | 0 to 6 | how many broad shallow channels, where the lava ran toward the sea |
| channelDepth | number | 22 | 0 to 40 m | how deep the channels cut below the plain |
| channelWidth | number | 450 | 200 to 900 m | the channels' half-width at the bottom of the bank |
| vents | integer | 3 | 0 to 6 | how many low shield vents stand on the plain |
| ventHeight | number | 160 | 10 to 250 m | how high the tallest low shield stands above the plain; lava shields run tens to a few hundred metres |
| ventRadius | number | 3 | 1.2 to 6 km | the radius of a typical shield at its base, where it meets the plain |
| flow | number | 8 | -50 to 50 deg | which way the lava ran, turned from straight toward the sea, in degrees toward along the shore |
| seed | integer | 3 | 0 to 999 | the dice behind the ridges, channels and vents; a different number, a different plain |
