Interactive Extraction and Re-Design of Sweep Geometries
James L. Andrews, Pushkar Joshi, Samantha De Carlo · 2011
We introduce two interactive extraction mod- ules that can t the parameters of generalized sweeps to large, unstructured meshes for immediate, high-level, detail-preserving modication. These modules represent two extremes in a spectrum of parameterized shapes: rotational sweeps dened by a few global parameters, and progressive sweeps forming generalized cylinders with many slowly varying local parameters. Both mod- ules are initialized and controlled by the user draw- ing a few strokes onto the displayed original model. We demonstrate the system on various shapes, rang- ing from clean, mechanical geometries to organic forms with intricate surface details.
