Is there a way to load las file(point cloud data) as Tile3DLayer on the map?

Hi, I am just a beginner with Web and Deck.gl .
I just wonder whether there is a way to load las file on the map.

import React, {useState} from 'react';
import {render} from 'react-dom';
import {StaticMap} from 'react-map-gl';
import DeckGL from '@deck.gl/react';
import {Tile3DLayer} from '@deck.gl/geo-layers';
import {COORDINATE_SYSTEM} from '@deck.gl/core';
import {CesiumIonLoader} from '@loaders.gl/3d-tiles';
import {Tiles3DLoader} from '@loaders.gl/3d-tiles';
import {PointCloudLayer} from '@deck.gl/layers';
import {LASWorkerLoader} from '@loaders.gl/las';
// import {PLYWorkerLoader} from '@loaders.gl/ply';
import {registerLoaders} from '@loaders.gl/core';

// Additional format support can be added here, see
// https://github.com/visgl/loaders.gl/blob/master/docs/api-reference/core/register-loaders.md
registerLoaders(LASWorkerLoader);
// registerLoaders(PLYWorkerLoader);

// Data source: kaarta.com
const LAZ_SAMPLE =
'http://localhost:8080/metuArch.las';
const layers3d = [
new PointCloudLayer({
id: 'laz-point-cloud-layer',
data: LAZ_SAMPLE,
coordinateOrigin: [ 126.97, 37.56],
coordinateSystem: COORDINATE_SYSTEM.METER_OFFSETS,
getNormal: [0, 1, 0],
getColor: [255, 255, 255],
opacity: 0.5,
pointSize: 0.5
})
];
return (

);
}

export function renderToDOM(container) {
render(, container);
}

If you are loading a single LAS file you want to use the PointCloudLayer. Check out e.g. https://loaders.gl/examples/pointcloud and https://github.com/visgl/loaders.gl/tree/master/examples/website/pointcloud.

Also, if you are displaying the LAS file on the map you need to position and scale your point cloud correctly. Perhaps using Layer.coordinateOrigin prop. loaders/deck does not read coordinate system information from LAS files.

Thanks for the help!
Actually, las file size is big, so that is why I try to use Tile3DLayer without uploading the file on Cesium.

That won't work. 3DTileLayer expects files to be divided into tiles before you start loading them.

[daqjjang]

Oh, I see.
Then is there way to convert las file to 3d tiles format?

If you don't want to use Cesium, you need to look around for open source tiling solutions. Perhaps the tool referenced in #4898.
