Title
Efficient and Precise Solid Modelling using a 3D Input Device
Abstract
To simultaneously model 3D objects efficiently and precisely seems somewhat contradictory. Several approaches have been developed to do either inaccurate but fast 3D sketching using 2D or 3D input devices or to model precisely with conventional 2D techniques. We believe that the reason why 3D input devices have not been successful outside of imprecise sketching is due to a lack of appropriate interaction techniques that drive 3D devices to their full potential. In this paper we show how a 3D input device can be used to model both rapidly and accurately. We focus on object creation and manipulation with a 3D input device and introduce a new paradigm which we call "topological-context-based modification". This technique uses the degrees of freedom of the 3D input device advantageously and places intuitive CAD-typical modification possibilities (such as change object parameter, move a plane, rotate around edge) at the user's disposal. Thus, bridging the gap between 3D sketching and detailed design.
