Interactive Evolutionary Algorithms (IEAs) allow designers to engage with the process of evolutionary development itself. This creates an involved experience, helping to explore the wide combinatorial space of parametric models without always knowing where you are headed.

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

In the fields of architecture and urban planning, graph theory has become an essential basic mathematical tool for quantitative research in many research directions (such as path optimization, facility distribution, spatial syntax, etc.).

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

FractureHopper is an extension of GH for fractal math and chaos theory. It extens grasshopper with a number of utilities: Julia 2D and 3D sets and tests, Lorenz attractors, Rabinovich-Fabrikant maps, Bifurcation diagrams.

Sandbox Topology is a set of tools for Grasshopper 0.9 that facilitate the topological analysis and filtering of line, polyline, mesh and brep networks.

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.

Mesh+ is a set of user objects which enable a wide range of mesh editing, creation, interaction, and topology modification within Grasshopper 3d.

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.

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

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.

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.

Extends Grasshopper’s ability to create and reference geometry including lights, blocks, and text objects. Also enables access to information about the active Rhino document, pertaining to materials, layers, linetypes, and other settings.

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.

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

Parking Solver is a plugin developed in my free time to automatize the layout planning of open plot parking lots. It contains several settings and custom methods to provide a wide variety of solutions within a simple and intuitive workflow (I guess).

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.

Wasp is a Grasshopper plug-in, developed in Python, offering combinatorial tools to design with discrete elements. The description of each part includes all information necessary for the aggregation process (part geometry, connections location and orientation). The connections define the topological graph of the part, which is used to define the possibilities of aggregation with other parts. Wasp offers a series of aggregation procedures, allowing geometry- and data-driven generation of structures. Additionally, it provides tools for constraining the resulting aggregation, both at the local and global level, as well as utilities to visualize and process it.

As a 3D CAD software suite, Rhino+Grasshopper is, at its core, a means to create, transform and manage data. Grasshopper’s explicit visual scripting interface structures these operations through the use of DataTrees. Treesloth emerged as a series of tools applied in both professional and research practice to help better negotiate the the types of data relationships within (and between) Grasshopper definitions that enable more complex operations.

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.
