Time compression characteristics of the Augmented Prototyping Pipeline

1. Introduction Current rapid prototyping techniques are of limited use in the early phases of design. In order to establish a more dynamic and effective means, the concept of augmented prototyping recently gained interest [Stork et al., 2002][Verlinden et al., 2003]. The concept of Augmented Prototyping combines Rapid Prototyping techniques to obtain 3D physical objects (e.g. Stereo lithography, NC milling), with Augmented Reality systems. For example, Figure 1 shows a NC milled foam model of a car on which a video projector directly beams digital 3D perspective renderings. In such a combination of physical and virtual prototyping, only a rough, global physical shape has to be manufactured, while
