Examples of syn3d.base.ActiveNode

syn3d.base.ActiveNode
Active nodes are a the plugin interface to build the 3D scene graph, which is itself mapped to the swing tree. They can represent any object for the scene, be it a Shape3D, a Transform group or an ambiant light. As their name suggests, they also bring their own possible actions. For example, a rotation transform may declare an action to rotate 90� on X axis, and so on. A switch group may declare actions to set its children visible or not. Etc... Another reason why this interface is neither the swing nor the 3D node, is for serialization. See the save/restore methods for comments. @author nicolas brodu
