Firefly is written in WebGL using the three.js library. This tool builds off of a previous version developed by Alessandro Febretti.

This project is funded by Northwestern's Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA), Northwestern's IT Research Computing group, and NSF grants AST-1412836, AST-1715216, and CAREER award AST-1652522 awarded to Claude-André Faucher-Giguère.

Additional Info

Firefly was originally designed for FIRE data, but has since been extended to support any particle data. This package should not be confused with the serendipitously named web-based visualization software Firefly, from Caltech-IPAC, a general tool for retrieving and viewing astronomy data.
