Jellyfish by Smei is an Implicit modeling plugin for Rhino Grasshopper. It utilized Ryan Schmidt(author of Autodesk Meshmixer)’s brilliant open-source geometry3Sharp library. The goal of the plugin is to provide an intuitive and fast way to model, manipulate and visualize implicit geometries.
Squid by Mateusz Zwierzycki enables to create drawings using Grasshopper. By utilizing Data Trees it can also render animations (as .png sequences). A marriage between raster and vector imaging, bounded with parametric interface.
Culebra.NET by Luis Quinones 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.
OctaTree plugin by samalika3 includes 3 capsules. They provide the algorithm of voxelization, based on octree structure. It works much faster then, f.e. creating the definition with a 3D array of points.
Hummingbird by Mario Guttman is a set of Grasshopper components that facilitate the creation of Revit native geometry. This process exports basic geometric properties and parameter data to CSV text files which are used to create Revit BIM geometry.
The goal of this library by camnewnham is to provide efficient and simple functionality to extend the creation, usage and display of meshes.
Starling mesh tools by Mateusz Zwierzycki. These components enable mesh parametrization, so it behaves like a surface – you can evaluate points at any place etc.
The ShortestWalk add-on for Grasshopper exposes one component which, given a network of curves and a list of lines, calculates the shortest route from line start point to line end points in a network. It is based on a topology calculator and the A* search algorithm.
Atträctor by Friedrich Söllner is an easy to use tool to transform grids according to given attractor geometry. This tool was developed for a beginners Grasshopper workshop at the Städelschule architecture class in Frankfurt/Germany.
GeoDex 3 GH by David Mans is the Grasshopper 3D implementation of the GeoDex Library, a collection of around 150 curve, surface, and volume equations.
Hoopsnake by yconst is a component that enables feedback loops within Grasshopper. What it does in principle is to create a copy of the data it receives at it’s input upon user request and store it locally.
Ladybug by Mostapha Sadeghipour Roudsari allows you to import and analyze standard weather data in Grasshopper; draw diagrams like Sun-path, wind-rose, radiation-rose, etc.
In this grasshopper definition by defining size of a rectangle you can create a parametric canvas which you can control with a number slider.
LunchBox by Nathan Miller is a plug-in for Grasshopper for exploring mathematical shapes, paneling, structures, and workflow.
Strawberry Lab is an initiative to create free tools for structural engineers to tackle specific bottle-necks in their workflow. Tools that they are creating are automating areas of modelling and loading for cases with large amounts of structural elements.
Peregrine is a LimitState:FORM powered optimization plugin for Grasshopper, the visual programming language and environment for Rhino3D.
Human UI by andheum is a new interface paradigm for Grasshopper. Create professional looking Grasshopper apps with custom user interfaces without writing any code.
SeaGrass is an adaptive surface panelling tool, that helps create Louvered Panels. SeaGrass is built against Grasshopper 1.0 (for Rhino 6.0).
OpenNest by petras_vestartas is a Grasshopper plugin with tools for unrolling, packing and of course nesting curves directly inside the definitions. The library is based on Boost 1.62 that is used to compute NFP – No Fit Polygon.
3D Graphic Statics by Ognjen Graovac is a structural form-finding method for generating compression-only spatial forms. The static equilibrium is described by using two reciprocal diagrams – form and force.
flowL by uto is a plug-in to visualize a vector field, generated through positive and negative point charges. The path lines are calculated with the “Runge-Kutta 4th Order Method” short “RK4”.
SuperMesh Toolkit by George Adamopoulos 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.
Discrete Vectors by ekimroyrp is a set of components for making discrete vectors out of continuous or random vector sets. Good for matching vectors to other closest predefined vectors to give curves, swarms, and flowlines that straight line aesthetic.
BrickDesign by ROB Technologies enables the controlled design and manipulation of a large amount of discrete elements. The plug-in provides a parametric design environment, which allows for a fast build-up of brick façade geometries.
Anemone by Mateusz Zwierzycki enables you to create loops in Grasshopper. The basic workflow relies on two main components : Loop Start and Loop End
PanelingTools plugin by Robert McNeel & Associates is integrated with Rhino and Grasshopper and is widely used by designers, architects, and building prefessionals. It supports intuitive design of paneling concepts as well as help rationalize complex geometry.
FabTools by Florian Frank is a set of Clusters, that enhances the ability of Grasshopper. The Tools are for fabrication purposes in Grasshopper and improve your workflow and accelerate your scripting tasks.
TPS by C.Robeller is a Grasshopper Plugin for the design of freeform Timber Plate Structures. It is meant for discrete structures, built from separate pieces which are connected with joints. The resulting meshes are not necessarily flat-foldable as in Origami.
Intralattice by dnkrtz, is a plug-in for Grasshopper used to generate solid lattice structures within a design space. It was developed as an extensible, open-source alternative to current commercial solutions, such as Within.
