OrthographicView

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.

<iframe height="450" style={{width:'100%'}} scrolling="no" title="deck.gl OrthographicView" src="https://codepen.io/vis-gl/embed/YzpXqzv?height=450&theme-id=light&default-tab=result" frameborder="no" loading="lazy" allowtransparency="true" allowfullscreen="true"> See the Pen deck.gl OrthographicView by vis.gl (@vis-gl) on CodePen. </iframe>

Constructor

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

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

flipY (boolean) {#flipy}

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

near (number, optional) {#near}

Distance of near clipping plane. Default 0.1.

far (number, optional) {#far}

Distance of far clipping plane. Default 1000.

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 | number[2], 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. For example zoom: 1 is 2x the original size, zoom: 2 is 4x, zoom: 3 is 8x etc.. To apply independent zoom levels to the X and Y axes, supply an array [zoomX, zoomY]. 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.

Controller

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

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

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