Interactive Sketching of Urban Procedural Models SIGGRAPH 2016

3D modeling remains a notoriously difficult task for novices despite significant research effort to provide intuitive and automated systems. We tackle this problem by combining the strengths of two popular domains: sketchbased modeling and procedural modeling. On the one hand, sketchbased modeling exploits our ability to draw but requires detailed, unambiguous drawings to achieve complex models. On the other hand, procedural modeling automates the creation of precise and detailed geometry but requires the
