LunchBox is a collection of computational design tools for Grasshopper and Dynamo. The plugins include new component nodes for managing data and geometry for activities such as generative form making, paneling, rationalization, and interoperability. LunchBox also includes new general-purpose Machine Learning components built on the Accord.NET framework. The components are available under the GNU Lesser General Public License in following from Accord.NET. You can access the project on Bitbucket!
LunchBox is a core technology that we use in our education and consulting work. LunchBox is and, always will be, free to use for educational and commercial purposes. LunchBox for Grasshopper has been in development since 2011 and is one of the most used plugins for Grasshopper with over 100,000 users worldwide.
* Note that we have discontinued the Dynamo versions of this tool. Current and future versions of LunchBox are built for Grasshopper. The source code for the Dynamo version can be found here under the GNU license.
