A series of algorithms and general-purpose tools User Objects for Grasshopper 3d, a visual scripting plugin developed by David Rutten for Rhinoceros 3d (v.5), by Robert McNeel and Associates. Many of these tools were inspired by Projects developed at Grimshaw Architects and Projects at Woods Bagot and are made available under the MIT License.
