Grasshopper Definitions
Grasshopper Curve on Surface Components
Crv_On_Srf Components
GH_Version: 0.7.x
Here are two components for adding a hexagon pattern and diagrid pattern over a surface. These components were created mostly as an exercise to translate from a .net component within grasshopper to a custom component.
Download the file from the link above and place into your C:\Program Files\Rhinoceros 4.0\Plug-Ins\Grasshopper\Components or equivalent (depending on your [...]
GH Shelling
Download: GH_Shelling.ghx
GH Version: 0.6.0059/0.7.0014
This definition takes one or more closed polysurfaces* and makes a closed polysurface shell representing the edges. Tested on simple polysurfaces with coincident verticies. Mix generated result with Giulio Piacentino’s Weaverbird for a smoother mesh version.
Definition tested in GH 0.6.0059 and 0.7.0014.

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.

GH Remap Values for GH 0.6.0043
Description: These functions will take one list of values, and map them to another list of values.
Grasshopper connection to OpenOffice

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 [...]
RhinoScripts
Rhinoscript connection to OpenOffice Calc
These scripts were written to connect from Rhinoscript and OpenOffice Calc, a spreadsheet program very similar to Microsoft Excel. The biggest difference between the two is that OpenOffice is opensource and free to download and use. This makes it much easier for us to implement spreadsheet based parameterization with clients and students because everyone has [...]
Rhinoscript: Fab PolySurface
Fab PolySrf v.1: Script takes a polysurface (in this case something that has been unrolled but not exploded) and prepares the geometry for fabrication with a laser cutter. Script organizes geometry into separate layers.
Print Parametric Field
Print Parametric Field Script + Sample File The script uses a method to divide the surface and pass the information to a matrix, but in this case we test the curvature of the surface and use that information to generate circles with a radius and orientation based on the Gaussian curvature value and normal direction [...]
Parametric Vector Field
Parametric Vector Field Script + Sample File
The script goes through the surface and evaluates the curvature on each division point, then creates a curve relative to the normal vector on each point of the surface. Curvature values at each evaluation point is considered in order to give length to the curves. The final lines in [...]
Image > Dot Pattern
subCirclePattern.rvb This script uses the RhinoScript GDI Bitmap Extension. In order for this script to work properly, you must download and correctly configure the plugin. The script prompts the user to select an image. Image types supported are JPEG, TIFF, PNG, BMP, EXIF, GIF, ICO, and RLE.
There is also a scale control. Circles are drawn [...]
