    • updateChildren

      protected void updateChildren(double time)
      Description copied from class: Spatial
      Override to allow objects like Node to update their children.
      Overrides:
      updateChildren in class Node
      Parameters:
      time - The time in seconds between the last two consecutive frames (time per frame). See ReadOnlyTimer.getTimePerFrame()

    • draw

      public void draw(Renderer r)
      Description copied from class: Node
      draw calls the onDraw method for each child maintained by this node.
      Overrides:
      draw in class Node
      Parameters:
      r - the renderer to draw to.

    • updateWorldBound

      public void updateWorldBound(boolean recurse)
      Description copied from class: Node
      updateWorldBound merges the bounds of all the children maintained by this node. This will allow for faster culling operations.
      Overrides:
      updateWorldBound in class Node
      Parameters:
      recurse - true to recurse down the scenegraph tree
