The class definitions for the internal nodes of the scene graph can be found in the VulkanSceneGraph/include/vsg/nodes directory. All scene graph nodes are subclassed from the vsg::Node base class. Examples that illustrate use of various node classes can be found in the vsgExamples/examples/nodes directory.
