GH Srf Subdivision Strategies for GH 0.6.0043 **REQUIRES WEAVERBIRD
Description: This definition is a collection of ten methods to subdivide surfaces. Collection includes UV Division, Physical Distance, and Mesh Algorithm subdivision strategies. Further Catmull-Clark mesh subdivisions thanks to Giulio Piacentino’s Weaverbird Plug-in for Rhino and Grasshopper. Below are examples of the subdivisions generated.

Grasshopper connection to OpenOffice
Downloads:
GH.OpenOfficeCXN for GH 0.6.0043
GH.OpenOfficeCXN for GH 0.6.0019
These scripts were written to connect from Grasshopper and OpenOffice Calc, a spreadsheet program very similar to Microsoft Excel. The definition will read and write OpenOffice Calc AND Microsoft Excel Files.
The biggest difference between the two is that OpenOffice is open source and free to download and use. This [...]
Grasshopper UDP Receiver
Synchronous UDP Receiver
GH version 0.6.0019
Description:
This definition allows receiving with the User Datagram Protocol through .net. Please note, this definition uses a synchronous structure, meaning Rhino/GH will hang until some data is received from an external application. Please run the included Processing Sketch in order to begin transmitting continuous data to GH.

vb.Net + Grasshopper: Surface Panels
Downloads:
GH.net_SrfPanels for GH 0.6.0043
GH.net_SrfPanels for GH 0.6.0012
Definition subdivides a surface into quad or triangular facets or ‘panels’ all inside a scripting component. Note: Image is basic definition + additional GH components.
vb.Net + Grasshopper Surface Curvature
Downloads:
GH.Net Surface Curvature for GH 0.6.0043
GH.Net Surface Curvature for GH 0.6.0012
This component will output a list of Gaussian Curvature and Mean Curvature values from a surface. The calculations are an adaptation from an article from the Rhino .net SDK wiki on calculating the Principle Curvatures at a specific point. The values are used to visualize [...]

GH Panel+Unroll for GH 0.6.0043
GH Panel+Unroll for GH 0.6.0012
Description: This definition panels a surface with triangular panels. These panels are reoriented and organized in order to produce a quad panel with a fold.
References: This definition references and takes inspiration from the following post found on Zach Downey’s website, DesignAnalyze:

GH Planar Hexagon Panels for GH 0.6.0043
GH Planar Hexagon Panels for GH 0.6.0012
Description: This definition uses a scripting component to define a hexagonal pattern on a referenced surface. The resulting curve verticies are projected to a reference plane in order to define a planar hexagon panel. Note: These are not water tight.
Brick Pattern

GH Brick Pattern for GH 0.6.0043
GH Brick Pattern for GH 0.6.0012
Description: This definition creates a series of bricks and rotates them according to an attraction point.
GH Crv Connect

GH Crv Connect for GH 0.6.0043
GH Crv Connect for GH 0.6.0012
Description: This definition takes input curves, divides them, and creates polylines across them. Version created for GH 0.6.0043 implements the Path Mapper component which was not available in GH 0.6.0012.

GH Umbrella for GH 0.6.0012
Description: This definition simulates an umbrella mechanism
Excel Field 01
Excel_Field_01: This definition uses the Excel Link written by Damien Alomar. Another script was written to take the values of the excel sheet (0-9) and filter them into different lists.
Hexagons on Surface
Downloads:
GH Surface Hexagon Pattern for GH 0.6.0043
GH Surface Hexagon Pattern for GH 0.6.0012
Description: Definition uses the VB.NET component to organize the user controlled division points of a surface. The result is a hexagonal pattern. User can increase and decrease the resolution.
Random Point Matrix
Downloads:
GH Random Point Matrix for GH 0.6.0043
GH Random Point Matrix for GH 0.6.0012
GH Random Point Matrix for GH 0.5.0060
Description: Definition uses the VB.NET node to generate a random matrix of points using the RandomClass inside of VB.net (for version 0043) to apply the randomness.
Louvers Between Splines
LOUVERS_BETWEEN_SPLINES: Definition generates a series of louvers between two generic splines. The louvers’ direction is determined by a point in space. Moving the point results in different orientations of the louvers
Panels 02
PANELS 02: Definition populate a single component on a generic double-curved surface. The sliders allow to control the number of the sides, the thickness and the size of the components.
SubSurface Sun Angle
SUB_SRF_SUN_ANGLE: Definition analizes the angle deviation of a set of points from a reference vector(sun). The sliders allow to define a sub-surface area and the UV subdivision amount. The angle between normal vectors at each point and the reference vector are plotted onto the surface for an immediate understanding of incidence conditions. Angles bigger or [...]

Polygon Spirals
POLYGON SPIRALS: Definition translates in Grasshopper the mathematical problem of polygon spirals. Polygons are drawn so that their vertexes are on the sides of the next larger polygon.
The sliders allow to modify the number of sides and the angle of the polygons
