Dynamo - dynamic 3D models for the web: a declarative approach to dynamic and interactive 3D models on the web using x3dom

Animations aid greatly to a presentation of a sophisticated man-made object. With additional interactivity, a user can explore such an object to gain even better understanding. The authoring of such dynamic models is often very resource demanding, as the animations and logic of interaction has to be expressed in an authoring program; often using a programming language. Furthermore, the 3D model and its dynamic capabilites are tightly coupled, which makes it costly to integrate changes of the underlying 3D model - e.g. if a machine part changes. Contribution and Benefit. We present a novel scheme to define varying states of a 3D model in a decoupled, declarative manner using pattern matching. Furthermore, we demonstrate its capabilites for the web with an open source JavaScript implementation that operates on an x3dom model.
