Abstract
Methods and apparatus for 3D sketching may provide an interface for creating 3D drawings from 2D and 3D input, and for creating 3D curve networks. The technique may provide tools for 2D sketching that enable 2D sketching in 3D space, and for creating a network of intersecting 3D curves. The technique may provide user interface elements and techniques that facilitate the curve drawing tasks. For 2D sketching, the technique may provide methods for interpreting imprecise user 2D strokes as continuous, high-quality 3D curves. The technique may provide the ability to edit existing 3D curves using sketched 2D strokes. The technique may enable sketching of 3D curves by rotating a drawing plane and/or by creating drawing surfaces on which curves may be added. The technique may provide user interface elements for converting curves in 3D space into a curve network.
