Paper Abstract:
|
We propose a novel mechanism for sketch-based 3D modeling, with which a user can select an appropriate interpretation
of the sketch from multiple candidates. In existing sketch-based modelers, each stroke specified by a user has been
uniquely mapped to a single operation. However, this one-to-one mapping between strokes and operations turns out to be
an obstacle when we add new operations to these modelers. Because the types of strokes, which can be geometrically
differentiated from each other, are limited in number, conflicts should necessarily arise in establishing a new mapping
between strokes and operations. To resolve these conflicts, we adopt a new approach, in which each stroke can be
mapped to multiple operations. The proposed mechanism pops up multiple subwindows, in which the effects of
operations corresponding to the given stroke are illustrated. Afterwards, the user will be prompted to select an appropriate
candidate from the pop-ups. Our mechanism allows us to integrate various operations of existing sketch-based modelers
into a single system. Furthermore, each operation can also correspond to multiple types of strokes, bringing users with
greater flexibility in drawing strokes and specifying operations. |
