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.

    • 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

      For additional information about using CSS with the scene graph, see the CSS Reference Guide.

      The URL of the user-agent stylesheet that will be used by this SubScene, or null if has not been set.
      Since:
      JavaFX 8u20

    • setUserAgentStylesheet

      public final void setUserAgentStylesheet​(String url)
      Set the URL of the user-agent stylesheet that will be used by this SubScene in place of the the platform-default user-agent stylesheet. If the URL does not resolve to a valid location, the platform-default user-agent stylesheet will be used.

      The URL is a hierarchical URI of the form [scheme:][//authority][path]. If the URL does not have a [scheme:] component, the URL is considered to be the [path] component only. Any leading '/' character of the [path] is ignored and the [path] is treated as a path relative to the root of the application's classpath.

      The RFC 2397 "data" scheme for URLs is supported in addition to the protocol handlers that are registered for the application. If a URL uses the "data" scheme and the MIME type is either empty, "text/plain", or "text/css", the payload will be interpreted as a CSS file. If the MIME type is "application/octet-stream", the payload will be interpreted as a binary CSS file (see Stylesheet.convertToBinary(File, File)).

      For additional information about using CSS with the scene graph, see the CSS Reference Guide.

      Parameters:
      url - the URL of the user-agent stylesheet
