Chevron DownAPI Reference


The OrthographicView class is a subclass of View that creates a top-down view of the XY plane. It is usually used for rendering 2D charts in non-geospatial use cases.

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


import {OrthographicView} from '';
const view = new OrthographicView({id, ...});

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

flipY (Boolean)

Whether to use top-left coordinates (true) or bottom-left coordinates (false). Default true.

View State

To render, OrthographicView 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].
  • 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.


By default, OrthographicView uses the OrthographicController to handle interactivity. To enable the controller, use:

const view = new OrthographicView({id: '2d-scene', controller: true});
