WebTOP: An X3D-Based, Web-Delivered, Interactive System for Optics Instruction
The Optics Project on the Web (WebTOP) is a 3D, interactive computer graphics system that visualizes optical phenomena. Its purpose is to help instructors teach and students learn about waves and optics. Originally, WebTOP was implemented using VRML, Java, and the External Authoring Interface, and required the use of the Microsoft Virtual Machine. This paper provides an introduction to a new version of WebTOP that uses X3D, Java, the Scene Access Interface, and the Sun Virtual Machine. The interface, modules, and implementation of this version are discussed.
