Using Firefly to view FIRE data¶

Quickstart¶

To easily create a FIRE Firefly visualization¶

After following the installation instructions:

# Import Firefly API
from firefly.data_reader import SimpleFIREreader

# The simple reader only needs the snapshot location
# Here we're using the shared Stampede2 directory as an example
reader = SimpleFIREreader(
    '/scratch/projects/xsede/GalaxiesOnFIRE/core/m12i_res7100/output/snapdir_600',
)

To view the Firefly visualization¶

# Spawn a server to host the visualization
from Firefly.server import spawnFireflyServer
process = spawnFireflyServer()

Now navigate to http://localhost:5000 in your web browser. Alternatively, if you’re using a Jupyter notebook, you can setup an IFrame:

# Jupyter notebook alternative:
# Create a window to view the data
from IPython.display import IFrame
IFrame("http://localhost:5000", width=1000, height=500)

Regardless of browser or notebook, the final step is to send the data to the visualization. This will update your web browser or IFrame.
