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 keyframes = {}
  const renderLayers = ...
  const lengthMs = 5000 // ms
  const width = 1920 // px
  const height = 1080 // px
  return new DeckScene({animationLoop, keyframes, data, renderLayers, lengthMs, width, height})
}

Methods

getProps(deckRef, setReady, onNextFrame): props

Supplies deck.gl properties from hubble.gl.

Parameters:

• deckRef (React.RefObject) - React ref eventually containing a deck object.
• setReady ((ready: boolean) => void) - Callback indicating webgl, scene, and deck are loaded. Scene is ready for rendering.
• onNextFrame ((nextTimeMs: number) => void) - Callback indicating the next frame in a rendering should be displayed.

render(Encoder, encoderSettings, onStop, updateCamera)

Start rendering.

Parameters:

• 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().

• updateCamera ((prevCamera: CameraKeyframes) => void, Optional) - Default: undefined.

This function is called just prior to rendering. This is useful for redefining the camera's keyframes during an apps lifecycle in response to users interacting with the map.

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.
