This plugin is a set of 330 components which focuses on Tweens, Blends, Morphs, Averages, Transformations, & Interpolations – essentially Shape Changing.

Clipper is a 2D polygon Clipper offering polygon boolean operations (clipping): Intersection, Join, Difference, XOR. Offsets for polygons and Minkowski Sum and Differences.

This addon have useful tools like different extend tools, convert Grasshopper script to geometry, modified pipe , math tools , text tools and more.

Firefly offers a set of software tools dedicated to bridging the gap between Grasshopper (a free plug-in for Rhino) and micro-controllers like the Arduino. 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.

Crystallon is an open source project for creating lattice structures using Rhino and Grasshopper3D. Each tool is left as a cluster which can be opened and modified at will, in the spirit of open source. We hope the community will continue to develop and contribute to Crystallon through the use of the Grasshopper group and Github.

The goal of this library is to provide efficient and simple functionality to extend the creation, usage and display of meshes.

Kangaroo is a Live Physics engine for interactive simulation, form-finding, optimization and constraint solving.

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 reconstructs the shape, subdivides any mesh, even made by polylines, and helps preparing for fabrication.

Dendro is a volumetric modeling plug-in for Grasshopper built on top of the OpenVDB library. It provides multiple ways to wrap points, curves, and meshes as a volumetric data type, allowing you to then perform various operations on those volumes. Dendro includes components for boolean, smoothing, offsets, and morphing operations.

Meshedit is a set of components which extend Grasshopper’s ability to work with meshes.

Wombat for GH is an open source series of miscellaneous utilities aimed at improving modeling processes by streamlining common tasks. It includes components for operating on geometry, lists, files and folders, and visualizing the geometric properties of surfaces and meshes. Originally developed by Andrew Heumann and Brian Ringley while members of the Woods Bagot Design Technology team, maintained by WB DT. Open source at https://github.com/woodsbagot/WombatGH

Cocoon is an add-on to McNeel’s Grasshopper visual scripting interface for Rhinoceros. Cocoon is a fairly straightforward implementation of the Marching Cubes algorithm for turning iso-surfaces into polygonal meshes.

Agent-Based Modeling for Designers + A new paradigm for 3D modeling utilizing agents. + Assign forces and behaviors to systems of agents to create interactions. + Utilize any data to drive the system. + Easily debug your system by displaying individual force vectors. + High performance, parallel algorithms, spatial data-structures. + Write your own custom forces, no coding required. + Open source framework for others to build custom behaviors. + Boid forces: Cohese, Separate, Align, & View. + Contain Agents within Brep, Box, Surface, and Polysurface environments. + Forces: Path Follow, Attract, Contain, Surface Flow, Seek, Arrive, Avoid Obstacle, Avoid Unaligned Collision, Sense Image, Sense Point, & more to come. + Behaviors: Bounce Contain, Kill Contain, Initial Velocity, Eat, Set Velocity, & more to come.

With the Oricut Plugin, you can design Parametric Patterns for Origami & Kirigami. You can also get started by downloading the example files from our website.

In PedSim®, People move from Start Gate to Destination Gate, following the shortest route, avoiding obstacles and other People. If they see a Target of their Interest, they will go to that Target, stay a while and re-route to the Destination Gate.

For designers who want to use the same flexible language everywhere, GhPython is the Python interpreter component for Grasshopper that allows to execute dynamic scripts of any type. Unlike other scripting components, GhPython allows to use the rhinoscriptsyntax to start scripting without needing to be a programmer. Once on-board and with some practice, you can also get the most of external Python and .Net modules and libraries.

Draw the name (or nickname) of Grasshopper objects with Draw Icons mode on. It also enriches the capsules when you zoom in to understand the component and visualise its data at a quick glance and you can display the group nicknames filling its box when the zoom is too low.

Here is a first prototype of 2 new tools (as a .gha plugin), one for thickening skeletons into closed quad meshes, and one for morphing geometry with a mesh cage.

Rabbit is an open-source plug-in for McNeel’s Grasshopper that simulates biological and physical processes.

FlexHopper offers very fast, particle-based physics simulation within Grasshopper. It let’s you simulate unconstraint particles, fluids, rigid and soft bodies, textile and spring system, inflatables and a combination of all these materials in one scene at unparalleled speed. You can add collision geometry, define custom constraints and emit new particles during runtime.
