OrbitView

The OrbitView class is a subclass of View that creates a 3D camera that rotates around a target position. It is usually used for the examination of a 3D scene in non-geospatial use cases.

It's recommended that you read the Views and Projections guide before using this class.

Constructor

import {OrbitView} from '@deck.gl/core';
const view = new OrbitView({id, ...});

OrbitView takes the same parameters as the View superclass constructor, plus the following:

orbitAxis (String, optional)

Axis with 360 degrees rotating freedom, either 'Y' or 'Z', default to 'Z'.

View State

To render, OrbitView needs to be used together with a viewState with the following parameters:

  • target (Number[3], optional) - The world position at the center of the viewport. Default [0, 0, 0].
  • rotationOrbit (Number, optional) - Rotating angle around orbit axis. Default 0.
  • rotationX (Number, optional) - Rotating angle around X axis. Default 0.
  • zoom (Number, optional) - The zoom level of the viewport. zoom: 0 maps one unit distance to one pixel on screen, and increasing zoom by 1 scales the same object to twice as large. Default 0.
  • minZoom (Number, optional) - The min zoom level of the viewport. Default -Infinity.
  • maxZoom (Number, optional) - The max zoom level of the viewport. Default Infinity.
  • minRotationX (Number, optional) - The min rotating angle around X axis. Default -90.
  • maxRotationX (Number, optional) - The max rotating angle around X axis. Default 90.

Controller

By default, OrbitView uses the OrbitController to handle interactivity. To enable the controller, use:

const view = new OrbitView({id: '3d-scene', controller: true});

Visit the OrbitController documentation for a full list of supported options.
