loaders.gl offers a category of loaders for loading point clouds from standard formats. For example, the following code adds support for LAS/LAZ files:

import {PointCloudLayer} from '@deck.gl/layers';
import {LASLoader} from '@loaders.gl/las';

new PointCloudLayer({
  data: 'path/to/pointcloud.laz',
  loaders: [LASLoader]
});

To install the dependencies from NPM:

npm install deck.gl
# or
npm install @deck.gl/core @deck.gl/layers

import {PointCloudLayer} from '@deck.gl/layers';
import type {PointCloudLayerProps} from '@deck.gl/layers';

new PointCloudLayer<DataT>(...props: PointCloudLayerProps<DataT>[]);

To use pre-bundled scripts:

<script src="https://unpkg.com/deck.gl@^9.0.0/dist.min.js"></script>
<!-- or -->
<script src="https://unpkg.com/@deck.gl/core@^9.0.0/dist.min.js"></script>
<script src="https://unpkg.com/@deck.gl/layers@^9.0.0/dist.min.js"></script>

new deck.PointCloudLayer({});

Inherits from all Base Layer properties.

• Default: 'pixels'

The units of the point size, one of 'meters', 'common', and 'pixels'. See unit system.

• Default: 10

Global radius of all points, in units specified by sizeUnits (default pixels).

• Default: true

This is an object that contains material props for lighting effect applied on extruded polygons. Check the lighting guide for configurable settings.

• Default: object => object.position

Method called to retrieve the position of each object.

• Default: [0, 0, 1]

The normal of each object, in [nx, ny, nz].

• If an array is provided, it is used as the normal for all objects.
• If a function is provided, it is called on each object to retrieve its normal.

• Default: [0, 0, 0, 255]

The rgba color is in the format of [r, g, b, [a]]. Each channel is a number between 0-255 and a is 255 if not supplied.

• If an array is provided, it is used as the color for all objects.
• If a function is provided, it is called on each object to retrieve its color.
