Karpenko et al [7] propose a system that is able to reconstruct a 3D model from 2D drawings. In their method the user
draws some of the lines that correspond to the model, and
the system infers other hidden contours and infers a smooth
solid 3D-shape from them. In methods from other authors ([8],
[9], [10], [11]) user-drawn strokes are applied to a 3D model
surface and serve as handles for controlling the geometry.
Users can easily add, remove or deform these control curves as
if working with a 2D drawing directly. While those systems
reconstruct 3D-models from detailed strokes, ours uses the
strokes to retrieve 3D-models from a database. The 3D-models
and the strokes to which they are associated don’t need to be
similar in shape
