Accessors

aabb

autoLayers

  • get autoLayers(): boolean

  • Gets wether this View will automatically create ViewLayers on-demand as ViewerObjects are created.

    Returns boolean

  • set autoLayers(autoLayers: boolean): void

  • Sets wether this View will automatically create ViewLayers on-demand as ViewerObjects are created.

    When true (default), the View will automatically create ViewLayers as needed for each new RendererObject.layerId encountered, including a "default" ViewLayer for ViewerObjects that have no layerId. This "default" ViewLayer ensures that a ViewObject is created in the View for every SceneObject that is created.

    If you set this false, however, then the View will only create ViewObjects for SceneObjects that have a scene!SceneObject.layerId that matches the ID of a ViewLayer that you have explicitly created previously with View.createLayer.

    Setting this parameter false enables Views to contain only the ViewObjects that they actually need to show, i.e. to represent only ViewerObjects that they need to view. This enables a View to avoid wastefully creating and maintaining ViewObjects for ViewerObjects that it never needs to show.

    Default value is `true``.

    Parameters

    • autoLayers: boolean

      The new value for atuoLayers

    Returns void

backgroundColor

backgroundColorFromAmbientLight

  • get backgroundColorFromAmbientLight(): boolean

  • Gets whether the canvas clear color will be derived from AmbientLight or View#backgroundColor when View#transparent is true.

    When View#transparent is true and this is true, then the canvas clear color will be taken from the ambient light color.

    When View#transparent is true and this is false, then the canvas clear color will be taken from View#backgroundColor.

    Default value is true.

    Returns boolean

  • set backgroundColorFromAmbientLight(
        backgroundColorFromAmbientLight: boolean,
    ): void

  • Sets if the canvas background color is derived from an AmbientLight.

    This only has effect when the canvas is not transparent. When not enabled, the background color will be the canvas element's HTML/CSS background color.

    Default value is true.

    Parameters

    • backgroundColorFromAmbientLight: boolean

    Returns void

colorizedObjectIds

gammaFactor

highlightedObjectIds

numColorizedObjects

numHighlightedObjects

numObjects

renderMode

  • get renderMode(): number

  • Gets which rendering mode this View is in.

    Default value is QualityRender.

    Returns number

  • set renderMode(renderMode: number): void

  • Sets which rendering mode this View is in.

    Default value is QualityRender.

    Setting a View's rendering mode will activate whatever effects (eg. SAO, edges, canas scaling) are configured to be active in that mode, while deactivating all other effects.

    Parameters

    • renderMode: number

    Returns void

selectedObjectIds

visibleObjectIds
