The following videos demonstrate the applications of some of our past and current work. Click the titles for larger versions of the videos

Shape from Sketch	[zipped avi]	[pdf paper]	This is a rapid modeling tool for automotive design that allows designers to convert their 2D paper sketches into 3D models.
SketchCAD	[zipped avi]	[pdf paper]	A sketch-based modeling tool for product design. Users can sketch free-form curves and surfaces, and modify the geometry with a pen.
SimuSketch	[zipped avi]	[pdf paper]	This is an updated version of our sketch-based diagram creation and editing tool. This application shows the technology at work on Matlab's Simulink package.
VibroSketch	[zipped avi]	[pdf paper]	A simple, multi-degree-of-freedom mass, spring,  damper system creation and analyis tool.
