Kangaroo is a Live Physics engine for interactive simulation, optimization and form-finding directly within Grasshopper. See More

DIVA-for-Rhino is a plugin which runs thermal, daylight, solar radiation, and glare simulations. Our goal is to bring validated environmental simulations directly to the conceptual design environments of Rhino and Grasshopper.See More

-Refract-Flow-Surface/Target Ray (reflect)Sonic is a Grasshopper plugin that allows you to cast multiple rays, calculate reflections(bounces), calculate flow paths down a sloped surface. (eg. water runoff) Plus Added Math components.See More

Millipede is a structural analysis and optimization component for grasshopper. It allows for very fast linear elastic analysis of frame and shell elements in 3d, 2d plate elements for in plane forces, and 3d volumetric elements. All systems can be optimized using built in topology optimization methods and have their results extracted and visualized in a variety of ways.In addition millipede implements a few basic geometric features [extraction of iso surface meshes from volumetric scalar fields…See More

goat is an optimization solver add-on component. It perfectly complements galapagos, David Rutten's evolutionary solver based on a randomized core. goat pursues a mathematical rigorous approach and relies on gradient-free optimization algorithms, delivering fast and deterministic results. At every run, goat will yield the same optimal result.goat is a drop-in replacement for galapagos. It is based on David Rutten's galapagos GUI and interfaces…See More

Firefly offers a set of comprehensive software tools dedicated to bridging the gap between Grasshopper, (a free plug-in for Rhino) the Arduino microcontroller and other input/output devices. It allows near real-time data flow between the digital and physical worlds – enabling the possibility to explore virtual and physical prototypes with unprecedented fluidity.See More

The Embryo project aims to apply genetic programming concepts to grasshopper, offering an alternative to top-down visual graph generation and manipulation.See More

Weaverbird is a topological modeler that contains many of the known subdivision and transformation operators, readily usable by designers. Instead of doing the work repeatedly, or sometimes using complicated scripts, this plug-in helps reconstructing shapes as meshes, subdivides and refines even polyline lists, and helps preparing the model for fabrication. Weaverbird is the first released addon for Grasshopper but the group is new, so please join it to participate in discussions, ask questions…See More

CHAMELEONChameleon is a plugin for both Grasshopper and Revit with a focus on interoperability, simulation, and efficient practice workflows. Chameleon’s main advantage is its ability to facilitate easy transfer of geometric data between Grasshopper and Autodesk Revit, but also includes other valuable tools to make life easier, both in Grasshopper and Revit.See More
