Use of 3D visualization and simulation (VizSim) content can be a very effective learning tool for illustrating complex concepts, developing physical intuition and practicing "learning by doing" in a broad range of subject areas. Unfortunately, there is still a lack of cost-effective authoring tools allowing course instructors to seamlessly integrate and reuse such VizSim content in today's training and education applications. This paper describes a VizSim component framework, runtime and authoring tool that enables the creation of reusable VizSim content for Advanced Distributed Learning (ADL) environments that is conformant with the Sharable Content Object Reference Model (SCORM). The intent of the design is to allow course developers and instructional designers to easily create interactive VizSim application content using commercial off-the-shelf (COTS) graphical models, animations and behaviors. The VizSim content produced using the component-based approach presented is highly reusable and has application across a wide range of industries, including: education, training, industrial design, maintenance, entertainment and information technology.
