Just a little blatant self promotion :)

If you have a basic knowledge of working with C# scripts in Grasshopper but want to take it to the next level and start building your own GHAs, you may be interested in the webinar I'm teaching tomorrow for performance.network. We will go through the basics of plug-in development - the structure of the code, how to get data in and out of a component, and the debugging…

I'm excited to announce I'll be teaching two upcoming Performance.Network webinars on my plug-in, Human UI for Grasshopper. Learn to create professional user interfaces for your Grasshopper scripts!

Sign up today - space is limited! Part 1 (Beginner) is on July 7 and Part 2 (Intermediate)…

I wrote a little script for myself that I thought might be useful to other GH developers or teachers. Feed it a component from any library (such as a plug-in you're developing), and it will list and describe all the components in that library. It can also generate a markdown-formatted text file, organized by the subcategory tabs in the GH…

Grasshopper by default allows you to save individual components and clusters as "user objects," which can be re-used over and over again. However, sometimes you want to save a group of components without clustering them - like a component with pre-defined value lists or sliders attached, or special configurations with plugins like kangaroo, honeybee, or anemone.

The attached script lets you do just that - create a user object that can automatically place multiple components at…

There is an ongoing debate in my office between those who like to organize their definitions with hidden wires for the sake of cleanliness, and those who hate them because it makes definitions hard to debug. In order to sidestep any drama, I made a little script that lets you switch all the wires in a document between "Hidden" and "Faint." It will leave all wires set to default alone.

I just finished putting together a beta version of a little project. It's a tweetbot powered by a grasshopper definition. The bot transforms a cube according to a series of operations you specify, and then tweets a picture of the resulting form. There are currently 10 formal operations that the bot understands:

split

bridge

stretch

scale

shearA (Shear angular)…

Check out my latest blog post, responding to Michael Graves’ recent article in the NYT, speculating on ways that digital design practices can learn from the way drawing functions as a design tool. …

Since David Rutten added to GH the ability to set a default text panel background color, I’ve had my panels set to be white instead of the default bright yellow. But in all my old definitions, the panels remain yellow, and it drives me nuts. I was going through and changing them manually when it occurred to me that there was a much better way, based on a trick I saw David mention in a…

Hey all - just added a post documenting my GH work for the artist Sarah Oppenheimer. Check it out here!

Hey all - 

While working on a project I came upon the need to do some unit conversion within GH, so I decided to write a script to handle this. I've attached it as a user object. It takes two strings, defining the input and output unit systems, in the form of "mm" or "in^2" or "yd^3" etc. It will then output the necessary conversion factor. It also optionally accepts a list of values, and will convert them for you if they are present. 

A word of caution: I…

There was a request for the basic definition I used to make this image.

Process:

Choose an image, and live trace it in illustrator. Expand the live trace, and save the illustrator file. Export the live trace as a jpg or other bitmap format. 

In Rhino, import the image with the PictureFrame command. Then import the illustrator file and scale the curves to the…

Here is the definition used to create the video seen here. Requires Kangaroo.

2013 update: this is probably a better way to go.
