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.

Alternate Interface: Control Grasshopper from iPod
Current exploration into alternative interfaces for presenting and interacting with associative models. Here we see two examples of communication from an iPod Touch 2g to McNeel’s Grasshopper plug-in for Rhino. This is made possible by Open Sound Control (OSC) and the User Datagram Protocol (UDP). In these examples, a Processing interface was utilized to show [...]
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 [...]
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 [...]
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.

Maya Fluid to Grasshopper via UDP
In a collaboration with Shajay Bhooshan, Autodesk Maya 2009 can communicate with McNeel’s Rhinoceros::Grasshopper. The work on communicating to and from Grasshopper via the user datagram protocol (UDP) was to effectively speed up communication between programs without the use of each program writing and reading a text file. This investigation was begun to open up [...]
Grasshopper <-> Processing v2: Live Input
Video on Grasshopper3d
Here is an example of continuous data being fed into Grasshopper from Processing via the User Datagram Protocol (UDP). Very simple data, very simple result…but its a promising step in this investigation. In addition to the vb.net receiver, I am using Giulio Piacentino’s “The Engine” component to continuously refresh the GH canvas. You [...]
Grasshopper <-> Processing talk via UDP
The following videos show communication between Grasshopper and Processing via the UDP protocol.
This is an example of communication through UDP in vb.net and processing. There is one receiving processing sketch which is listening to UDP data from another processing sketch and a grasshopper definition.
This is an example of getting data (although very simple) into [...]
vb.net + grasshopper: adaptive surface subdivision
A quick translation of Rhinoscript to vb.net in order to control a recursive function inside of Grasshopper. First video shows that as the surface facets grow in area, the facet will subdivide further. Second video shows recursion based on the distance from an attraction point. Images show adaptation to multiple attraction points. The function will [...]
