com.jme3.scene.Geometry
Geometry defines a leaf node of the scene graph. The leaf node contains the geometric data for rendering objects. It manages all rendering information such as a {@link Material} object to define how the surfaceshould be shaded and the {@link Mesh} data to contain the actual geometry. @author Kirill Vainer
