Flux2o at Autodesk University 2018

Implementation of the Dijkstra Algorithm using Grasshopper and viewable in a web app

Flux2o is a full-fledged technology demonstrator of a workflow spanning Autodesk Revit and the Grasshopper plugin for Rhino3d using a Web Application as the intermediary.

Description

This project demonstrates collaborative workflows for using intelligent model data to perform wayfinding analyis and egress compliance checks.The first part of this two-part demonstration walks through a popular ‘Shortest Walk’ algorithm to evaluate egress conditions of a single floor plate using the Grasshopper Visual Programming interface. The second part demonstrates the process of transferring room and door data from Autodesk Revit to Grasshopper via the internet and back again. This project was built in collaboration with Neil Katz, Computational Designer and Associate Director at Skidmore, Owings, and Merrill LLP, New York.
