Firefly Demonstration

Firefly is a portable web-based 3d visualization software developed in partnership between the Northwestern University Galaxy Formation and Visualization groups. It was developed with the data output of the FIRE simulations in mind but can visualize any 3d dataset (in coordinate or phase space). In this video I demonstrate some of the key features of Firefly and how to use them using a snapshot of a Milky Way-like galaxy from the FIRE-2 set of simulations. This Firefly scene is the result of loading the JSON files produced by the jupyter notebook found at Firefly is currently in active development and can be found at A demo of the current build can be found at
