Andrea Rossi is an architect, researcher, and creative coder. He is the developer of WASP, an open-source Grasshopper plug-in to design discrete aggregations of modular elements. Andrea will be giving a lecture and Q&A session at the Computational Design: NEXT 10 conference. Wasp is a Python-based Grasshopper plug-in that provides combinatorial tools for designing with discrete pieces. Each part’s description contains the information required for the aggregate process (part geometry, connections location, and orientation). The connections create the part’s topological network, which determines aggregation possibilities with other factors. Wasp provides a set of aggregation algorithms that enable the creation of structures based on geometry and data. It also includes utilities for visualizing and processing the resultant aggregate and tools for restricting it both locally and globally.
