Class ViewRenderStateInternal

constructor

• new ViewRenderState(
      renderContext: RenderContext,
      pickManager: PickManager,
      renderManager: RenderManager,
      view: View,
  ): ViewRenderState

  Creates a ViewRenderState.

  Parameters

  • renderContext: RenderContext

    Shared render context used for WebGL access and shared resources.
  • pickManager: PickManager

  • renderManager: RenderManager

    Render manager used to draw this view.

renderBuffers

saveCanvasBoundary

view

beginSnapshot

• beginSnapshot(params?: { height: number; width: number }): void

  Begins a snapshot operation for this view.

  Intended to prepare any render buffers and state required to render the view into an offscreen snapshot target (eg. for displaying the last rendered frame when the view is inactive).

  Parameters

  • Optionalparams: { height: number; width: number }

    Optional snapshot parameters.

    • height: number

      Snapshot height in CSS pixels.

    • width: number

      Snapshot width in CSS pixels.

  Returns void

  Remarks

  This method is currently a stub. A typical implementation might:

  • allocate/resize a "snapshot" render buffer in renderBuffers
  • render the view using RenderManager
  • read pixels to an image for display in the view's HTML element (if it is an <img>)

destroy

• destroy(): void

  Releases per-view rendering resources.

  Returns void

  Remarks

  After calling this, the instance should not be used again.
