Multi-view Sketch-Based FreeForm Modeling

For the generation of freeform 3D models, one of the most intuitive solution is to use sketch-based modeling environments. Unfortunately, since the user interface relies upon the analyse of sketches in order to determine which action is requested by the user, the possible amount of different operations can be limited. In this paper, we present a 3D sketching system based on multiple views. Each view is specialized on a component of the modeling process (like the skeleton, the profile, etc.), and is based on specific sketching interactions. With this approach, an user could improve its understanding of the modeling process and perform a larger range of modeling operations.
