Description

A long-standing dream in computer-aided design is the possibility of using freehand sketching as the language for interactive design. The ability to sketch a 3D object, predict its performance, and re-design it interactively based on physics-based feedback would bring the power of state-of-the-art CAD tools into the critical, early design phase.

The enormous potential of sketch-based interfaces is widely recognized, and has been broadly pursued. However, the practical use of such attempts has remained limited because these interfaces have been primarily 2D, losing much of the benefit of mainstream 3D CAD. In order to become truly 3D, a sketch interface must automatically be able to reconstruct the spatial geometry from a single 2D sketch in near real-time, much like a human observer does implicitly.

3-D Journal Project is a demonstration of live sketching, written for TabletPC, using the Microsoft .NET platform and the Pen SDK.
