abstract = {This paper presents a hybrid method for creating three-dimensional
shapes by sketching silhouette curves. Given a silhouette curve,
we approximate its medial axis as a set of line segments, and
convolve a linearly weighted kernel along each segment. By summing
the fields of all segments, an analytical convolution surface is
obtained. The resulting generic shape has circular cross-section,
but can be conveniently modified via sketched profile or shape
parameters of a spatial transform. New components can be similarly
designed by sketching on different projection planes. The
convolution surface model lends itself to smooth merging between
the overlapping components. Our method overcomes several
limitations of previous sketched-based systems, including
designing objects of arbitrary genus, objects with semi-sharp
features, and the ability to easily generate variants of shapes.},
