Use it

Code for the specimen as it is set up above; it follows your knobs.

JavaScript

import { createAsset } from 'https://gaitkit.com/cdn/rock-arch.mjs';

const rockArch = createAsset();
scene.add(rockArch);                      // rests on y = 0, front faces +Z

JSX

import { useMemo } from 'react';
import { createAsset } from 'https://gaitkit.com/cdn/rock-arch.mjs';

export function RockArch() {
  const model = useMemo(() => createAsset(), []);
  return <primitive object={model} />;
}

GDScript

# Import rock-arch.glb (download below). It is a static mesh, one material per colour.
add_child(preload("res://rock-arch.glb").instantiate())

// Import rock-arch.glb with glTFast (com.unity.cloud.gltfast).
// Drop it in the scene: 1 unit = 1 metre, +Z is its front.

Knobs

Knob	Type	Values	Default	What it does
`biome`	choice	`desert` `grass` `snow` `rock` `volcanic` `alien`	`desert`	Rock colours shared with every Terrain piece: desert (banded red-orange sandstone), grass (grey stone with turf on top), snow (blue-grey under snow), rock (bare grey with moss), volcanic (black basalt), alien (blue stone).
`span`	range	3 to 10, step 0.5	`6`	Distance between the feet in metres (the opening is a bit narrower).
`shape`	choice	`round` `tall` `flat`	`round`	round (classic arch about 0.6 of the span high), tall (a pointed, nearly span-high window) or flat (a low natural bridge).
`thickness`	range	0.6 to 1.5, step 0.1	`1`	How massive the rock is: 0.6 is a delicate fin about to fall, 1.5 a heavy buttressed span.
`seed`	range	1 to 50, step 1	`5`	Changes the weathering, the lean of the legs and the rubble.

Presets: delicate arch {"span":5,"shape":"tall","thickness":0.7} · stone bridge {"span":9,"shape":"flat","thickness":1.3,"biome":"grass"} · frozen gate {"biome":"snow","span":4,"seed":12}
