Teaser: Two mesh cutting results produced by our iCutter tool. The user only needs to roughly draw a stroke (in purple) around the desired cutting boundary. iCutter obtains the similar cuts no matter how the user draws the strokes in different way.
Abstract
We present a novel
sketch-based tool, called iCutter (short for Intelligent Cutter), for
cutting out semantic parts of 3D shapes. When a user performs a cutting
task, he only needs to draw a freehand stroke to roughly specify where
cuts should be made without much attention. Then iCutter intelligently
returns the best cut that meets the user¨s intention and expectation. We
develop a novel scheme for selecting the optimal isoline from a
well-designed scalar field induced from the input stroke, which respects
the part saliency as well as the input stroke. We demonstrate various
examples to illustrate the flexibility and applicability of our iCutter
tool.
