DeckAdapter

Constructor

new DeckAdapter(sceneBuilder);

Parameters

sceneBuilder ((animationLoop) => Promise<DeckScene> | DeckScene)

Function to build scene, async or sync. See DeckScene for more information.

async function sceneBuilder(animationLoop) {
  // See DeckScene API Reference for more info
  const data = await fetch(...)
  const lengthMs = 5000 // ms
  const width = 1920 // px
  const height = 1080 // px
  return new DeckScene({animationLoop, data, lengthMs, width, height})
}

Methods

getProps(deckRef, setReady, onNextFrame, getLayers): props

Supplies deck.gl properties from hubble.gl.

Parameters:

  • deckRef (React.RefObject) - React ref eventually containing a deck object.
  • setReady ((ready: boolean) => void, Optional) - Callback indicating webgl, scene, and deck are loaded. Scene is ready for rendering.
  • onNextFrame ((nextTimeMs: number) => void, Optional) - Callback indicating the next frame in a rendering should be displayed.
  • getLayers ((scene: DeckScene) => any[], Optional) - Callback to construct deck.gl layers provided the scene. If set, deck.layers will be set to the layers returned by this function.
render(getCameraKeyframes, Encoder, encoderSettings, onStop)

Start rendering.

Parameters:

  • getCameraKeyframes (() => CameraKeyframes, Optional).

This function is used to access the camera's keyframes, and is called just prior to rendering.

  • Encoder (typeof FrameEncoder, Optional) - Default: PreviewEncoder.

Provide a FrameEncoder class for capturing deck canvas. See Encoders Overview for options.

  • encoderSettings (Object, Optional) - Default: {}.

See FrameEncoder for internal defaults.

  • onStop (() => void, Optional) - Default: undefined.

This function is called after the last frame is rendered. It does not get called when a render is interrupted with stop().

stop(callback)

Interrupt rendering and saves partial result. This is useful for handling user interruptions.

Parameters:

  • callback (() => void, Optional) - Callback indicating the rendering is finished.
