Usage

import {QuantizedMeshLoader} from '@loaders.gl/terrain';
import {load} from '@loaders.gl/core';

const options = {
  'quantized-mesh': {
    bounds: [0, 0, 1, 1]
  }
};
const data = await load(url, QuantizedMeshLoader, options);

Options

Option	Type	Default	Description
`quantized-mesh.bounds`	`array<number>`	`[0, 0, 1, 1]`	Bounds of the image to fit x,y coordinates into. In `[minX, minY, maxX, maxY]`.
`terrain.skirtHeight`	`number`	`null`	If set, create the skirt for the tile with particular height in meters

Remarks

Future Work

Skirting. The Quantized Mesh format includes data on which vertices are on each edge, which should assist in creating a skirt.
Use optional Quantized Mesh extensions, such as vertex normals.
Closer integration into tile culling. Quantized Mesh headers, the first 88 bytes, describe a tile's bounding volume and min/max elevations. Just the headers could be parsed while deciding whether the tile is in view. Upon verifying visibility, the rest of the tile's data can be parsed.
