Jellyfish is an Implicit modeling plugin for Rhino Grasshopper. It utilized Ryan Schmidt(author of Autodesk Meshmixer)’s brilliant open-source geometry3Sharp library.

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

XOLOTL provides a set of components for volumetric modeling in Rhino Grasshopper. They work based on the principle of signed distance functions (SDF). In boundary representations (BRep), objects are defined by vertices connected by edges and faces. In function representations (FRep), objects are defined by a function f that maps any point (x,y,z) to a real value d, the distance to the objects: f(x,y,z)=d

SuperMesh Toolkit allows you to easily design a large variety of regular or irregular patterns on NURBS Surfaces of any curvature, by tessellating them to special quad-like Meshes, topologically structured in rows and columns.

tOpos is a 3D Topology Optimisation plugin which is using GPU for computation acceleration. It is based on CUDA technology provided by NVIDIA. Current version of tOpos require NVIDIA graphic card with Cuda Computation Capability (cc) higher or equal to 3.0. Here you can check if you generation of GPU is compatible with tOpos. Also check if you drivers are up to date (do not use Windows Update drivers! Install newest drivers form NVIDIA website). Your graphic card drivers version need to be at least 376.51.

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

EleFront v4.3.0 is the Rhino 6 legacy release.  Component names and icons have been changed to make it easy to distinguish from the new version. Only install if you want to have the stable version and the beta installed side by side. If you are not testing the beta and only work in Rhino 6, install version 4.2.2 instead.  Version 4.3.0 works in Rhino 7 as well, but does not implement any of the new features that are present in Rhino 7 only.

Curve plus is a collection of curve modifier components developed over several years and wrapped up in this little library. The components range from simply exposing Rhinocommon curve commands, like spirals and control point weighting, to new tools like blending corners and a range of radial spirals. These components integrate into existing Grasshopper Curve, Vector, and Mesh tabs.

The plugin consists of a multithreaded simulation core and a set of tools for defining particle behaviors as well as their environment. Nuclei features unique voxel implementations for a powerful approach where particles adapt their behavior based on the highly customizable environment.

3D Graphic Statics is a structural form-finding method for generating compression-only funicular structures.

You can download some of your own leaf texture materials from the Internet

A DISCRETE ASSEMBLY TOOLKIT FOR ARCHITECTS AND DESIGNERS Monoceros is a legendary animal living in the huge mountains in the interior of India. Monoceros has the body of a horse, the head of a stag, the feet of an elephant and the tail of a boar.

This plugin includes 3 capsules. They provide the algorithm of voxelization, based on octree structure. It works much faster then, f.e. a creating of the definition with a 3D array of points.

Generate Minimal Surfaces from boundary curves or do a minimal relaxation on a mesh.

Culebra.NET is a 2D|3D Multi Object Behavior library written in C# (Wrapper around Culebra Java library) focused on hybrid system interactions with custom Visualization, Data, and performance features. It contains a collection of objects and behaviors for creating dynamic multi agent interactions. For more information see the Culebra Java Library.

ShapeMap is a plugin for Grasshopper, developed by the McNeel Asia China team. It integrates multiple basic functions in Rhino and has undergone secondary development. This plugin allows users to map any curve texture designed on a plane onto the surfaces of complex 3D models, while minimizing or eliminating deformation of the texture curves on the 3D surfaces. With ShapeMap, designing textures on 3D model surfaces becomes much easier, and the operation process is intuitive and simple.

Zebra is a C# grasshopper plugin, developed by YFA team when a need came for an agent based design plugin

Tools for the design of freeform Timber Plate Structures (TPS)

Ladybug allows you to visualize and analyze weather data in Grasshopper. This includes diagrams like the sun path, wind rose, psychrometric chart, etc., as well as studies of geometry like radiation analysis, shadow studies, and view analysis.
