Interactive Extraction and Re-Design of Sweep Geometries
Abstract
We introduce two interactive extraction modules that can fit the parameters of generalized sweeps to large, unstructured meshes for immediate, high-level, detail-preserving modification. These modules represent two extremes in a spectrum of parameterized shapes: rotational sweeps defined by a few global parameters, and progressive sweeps forming generalized cylinders with many slowly varying local parameters. Both modules are initialized and controlled by the user drawing a few strokes onto the displayed original model. We demonstrate the system on various shapes, ranging from clean, mechanical geometries to organic forms with intricate surface details.
