Interactive 3D Animation System for Web3D

We developed a personal Web3D system more than a decade which consists of 1) simple measuring method of 3D objects, 2) automatic annotation system, 3) efficient viewer, and 4) 3D object analyzing technique. Recently, we extended the system with 3D animation. With the system, not only 3D objects are automatically animated with predetermined parameters along single time-line, but also an interactive operation on asynchronous motion is realized. To achieve this, we propose a state transition model considering a state of 3D object linked with 3D animation. By using the model, independent animations are played according to the users interaction. Furthermore, intuitive interface based on gesture is implemented with tablet PC.
