Older version of Hapke

Hapke in Python

TODO

• add a system for showing progress messages during section runs
  • make the main / handler async
  • have the /progress handler cache messages until requested
  • have the JS poll a /progress endpoint at regular intervals until done
• move the ProgramState object to a separate file
  • make the cli UI use ProgramState as well

Code structure

Entry-points to the Hapke codebase:

• web.py: Starts the web-based Hapke interface.
• cli.py: Runs all the Hapke code from the command line, without prompting the user for additional information.
• rc_demo.py Simple web UI for playing with radiance coefficients.

Each of the above relies on some of these support modules:

• analysis.py: Contains the meat of the Hapke code.
• hapke_model.py: Provides an object representing the Hapke model, useful for caching intermediate values and keeping track of the moving parts.
• mplweb.py: Handles the web UI plumbing, including websockets.

Additional files:

• ui.html: The HTML template used for the main web UI.
• html/: Static files needed for the main web UI.
