For example, consider a render operation that takes transformations into account: while recursively traversing down the scene graph hierarchy, a pre-render operation is called. If the node is a transformation node, it adds its own transformation to the current transformation matrix.
Various free and open-source canvas or scene-graph libraries allow developers to construct a user interface and/or user-interface elements for their computer programs. Examples of free and open-source scene-graph canvas options include: in C, Evas (in EFL) from the Enlightenment project; in C, Clutter, associated with the GNOME project
OpenSG is a scene graph like many others, but with a number of unique features that set it apart from others. It features a blocked state management system to reduce the overhead for state change optimization, highly flexible traversal and other mechanisms to allow run-time exchange and enhancement of core data structures, but the most unusual aspect is its multi-threading approach.
OpenSceneGraph is an open-source 3D graphics application programming interface (library or framework), [2] used by application developers in fields such as visual simulation, computer games, virtual reality, scientific visualization and modeling.
Java 3D is a scene graph-based 3D application programming interface (API) for the Java platform. It runs on top of either OpenGL or Direct3D until version 1.6.0, which runs on top of Java OpenGL (JOGL). Since version 1.2, Java 3D has been developed under the Java Community Process. A Java 3D scene graph is a directed acyclic graph (DAG).

The representation of primitive scene data was optimized to minimize the amount of data stored so as to avoid completely duplicating it on a thread-by-thread basis. One of the unique features of XSG was the ability to replace most of the built-in methods for walking the graph with their own versions.
The section "Scene graphs and spatial partitioning" could use a concrete example, and probably a diagram, to explain the hybrid data structures it's talking about. In fact, the whole article could use more illustrations. -- Beland 23:20, 2 December 2014 (UTC)
