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

The voxeltools offer lightweight voxel geometry for Rhino. It allows you to quickly generate and manipulate voxelated geometry from meshes, breps, curves and points, and offers boolean operation between voxelgrids. It can convert voxelgrids to solid mesh hulls.

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.).

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

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.

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

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.

Biber is a plug-in for Rhino-Grasshopper which enables parametric joinery. It enables the joinery industry to take advantage of the parametric design workflow and makes design and production easier and more affordable. this plug-in is being developed in collaboration with Hochschule Mainz, Germany (Prof. Klaus Teltenkötter, Sascha Urban)

Nursery is a behavioural design framework for Grasshopper. It consists of a set of tools for creating Agents and Behaviours and executing these behaviours on a multithreaded simulation core.

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

Just an usual mesh pipe and mesh sweep. Find both in Mesh->Primitive panel.

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.

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.

The BOID library operates exclusively with Agent locations (Grasshopper points) and Agent motion vectors (Grasshopper vectors). Each component calculates specific motion vector based on certain Agent behavior. The vectors need to be aggregated into a compound vector and iteratively applied insode an Anemone loop.

Leopard is an open source mesh processing solution for grasshopper that allows users to interact with rhino geometry and create customised mesh shapes. By selecting Mesh vertices, edges and faces, users have more freedom to edit meshes intuitively and use different subdivision schemes to selectively choose multiple areas to fix.

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

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

Scatter is a grasshopper Add-On to distribute geometry with attributes.

Droid is a 3D printing related Grasshopper Plug-in Library add-on, with control over model Slicing, Custom paths and Gcode generation.
