The paper presents JavaBeans component model usage as the base for implementing 3D-modeling and visualization software. 3D-objects moleling is organized by means of JavaBeans components set that corresponds to a subset of base object types found in standard 3D-modeling languages with addition of some component types that enhance capabilities of the 3D-modeling languages. The practical result is represented by lightweight JavaBeans components library (pure 100% java) used to build Java-applets and application.
