Spatial augmented reality (SAR) makes possible the projection of virtual environments into the real world. In this demo, we propose to demonstrate our SAR tools dedicated to the creation of physical drawings. From the most simple tools: the projection on virtual guidelines enabling to trace lines and curves to more advanced techniques enabling stereoscopic drawing through the projection of a 3D scene. This demo presents how we can use computer graphics tools to ease the drawing, and how it will enable new kinds of physical drawings.
