A 3D Sketching Interacting Tool for Physical Simulation Based on Web

Sketching interface, as a user-friendly means for expression and communication, is not only an important medium for inputting 3D objects, but also a significant step of visualizing user’s conceptual ideas. To bring early sketching interface to network utilities, the paper defines several rules that can create and edit 3D models. These gesture schemes support both regular and freeform modeling, and can be embedded in multi-user interface through network. A brief introduction about sketch-based collaboration in client-server architecture is proposed. A tool with this sketch interface and physical simulation functionalities is presented. The experimental results show that it can explore users’ ideas in aiding 3D collaboration in network environment.
