Creating Principal 3D Curves with Digital Tape Drawing

(2002)

Abstract

Previous systems have explored the challenges of designing
an interface for automotive styling which combine the
metaphor of 2D drawing using physical tape with the
simultaneous creation and management of a corresponding
virtual 3D model. These systems have been limited to only
2D planar curves while typically the principal characteristic
curves of an automotive design are three dimensional and
non-planar. We present a system which addresses this
limitation. Our system allows a designer to construct these
non-planar 3D curves by drawing a series of 2D curves using
the 2D tape drawing technique and interaction style. These
results are generally applicable to the interface design of 3D
modeling applications and also to the design of arm’s length
interaction on large scale display systems.
