public class SubScene
extends Node
The SubScene class is the container for content in a scene graph. SubScene provides separation of different parts of a scene, each of which can be rendered with a different camera, depth buffer, or scene anti-aliasing. A SubScene is embedded into the main scene or another sub-scene.

An application may request depth buffer support or scene anti-aliasing support at the creation of a SubScene. A sub-scene with only 2D shapes and without any 3D transforms does not need a depth buffer nor scene anti-aliasing support. A sub-scene containing 3D shapes or 2D shapes with 3D transforms may use depth buffer support for proper depth sorted rendering; to avoid depth fighting (also known as Z fighting), disable depth testing on 2D shapes that have no 3D transforms. See depthTest for more information. A sub-scene with 3D shapes may enable scene anti-aliasing to improve its rendering quality.

The depthBuffer and antiAliasing flags are conditional features. With the respective default values of: false and SceneAntialiasing.DISABLED. See ConditionalFeature.SCENE3D for more information.

Possible use cases are:

  • Mixing 2D and 3D content
  • Overlay for UI controls
  • Underlay for background
  • Heads-up display

A default headlight will be added to a SubScene that contains one or more Shape3D nodes, but no light nodes. This light source is a Color.WHITE PointLight placed at the camera position.

      public SubScene​(Parent root, double width, double height)
      Creates a SubScene for a specific root Node with a specific size.
      Parameters:
      root - The root node of the scene graph

    • SubScene

      public SubScene​(Parent root, double width, double height, boolean depthBuffer, SceneAntialiasing antiAliasing)
      Constructs a SubScene consisting of a root, with a dimension of width and height, specifies whether a depth buffer is created for this scene and specifies whether scene anti-aliasing is requested.

      A sub-scene with only 2D shapes and without any 3D transforms does not need a depth buffer nor scene anti-aliasing support. A sub-scene containing 3D shapes or 2D shapes with 3D transforms may use depth buffer support for proper depth sorted rendering; to avoid depth fighting (also known as Z fighting), disable depth testing on 2D shapes that have no 3D transforms. See depthTest for more information. A sub-scene with 3D shapes may enable scene anti-aliasing to improve its rendering quality.

      Parameters:
      root - The root node of the scene graph
      width - The width of the sub-scene
      height - The height of the sub-scene
      depthBuffer - The depth buffer flag
      antiAliasing - The sub-scene anti-aliasing attribute. A value of null is treated as DISABLED.

      The depthBuffer and antiAliasing flags are conditional features. With the respective default values of: false and SceneAntialiasing.DISABLED. See ConditionalFeature.SCENE3D for more information.

      Throws:
      NullPointerException - if root is null
