| Man-made objects are largely dominated by a few typical features that
carry special characteristics and engineered meanings. State-of-the-art
deformation tools fall short at preserving such characteristic features
and global structure. We introduce iWires, a novel
approach based on the argument that man-made models can be distilled
using a few special 1D wires and their mutual relations. We
hypothesize that maintaining the properties of such a small number of
wires allows preserving the defining characteristics of the entire
object. We introduce an analyze-and-edit approach, where prior to
editing, we perform a light-weight analysis of the input shape to
extract a descriptive set of wires. Analyzing the individual and mutual
properties of the wires, and augmenting them with geometric attributes
makes them intelligent and ready to be manipulated. Editing the object
by modifying the intelligent wires leads to a powerful editing framework
that retains the original design intent and object characteristics. We
show numerous results of manipulation of man-made shapes using our
editing technique. Video Direct
