The paper describes web-based 3D interactive systems, including its background, key technologies, and applications. Then the paper presents three kinds of systems, which have been implemented based on difference approaches. Virtual assembly systems is based on VRML technologies, E-manual system for fishing reel maintenance is based on 3D animation, and concurrent engineering system for jig design and production is based on Cult 3D technologies. Comparing these systems designed for different objectives, the paper clarifies the key ideas to implement an effective 3D interactive system, which could be evaluated in various applications.
