DescriptionImmersive 3D drawing applications increasingly produce unstructured 3D strokes as output. We propose a method to transform these sketches into piecewise-smooth surfaces. Starting with an initial proxy surface, we iteratively segment the surface into smooth patches joined sharply along some strokes and optimize these patches to fit surrounding strokes.
