 `Drosophila eye map`_
=======================

.. _drosophila eye map: http://code.astraw.com/projects/drosophila_eye_map

Overview
========

This software package concerns the eye-map of `Drosophila
melanogaster` made by <NAME> during his diplom thesis in
1971. This eye map was published in Heisenberg and Wolf (1984). These
data were digitized from a scan of the photo in the book and coverted
to 3D and saved to the included file
receptor_directions_buchner71.csv.

   melanogaster` eye map overlaid on a colormap showing
   interommatidial distance averaged over each ommatidiums nearest
   neighbors. (This image was generated using the
   make_buchner_interommatidial_distance_figure.py script included in
   the package.)

History
=======

These programs and files have been extraced from <NAME>'s
"fsee" `software package`_ for simulating the visual world of
Drosophila described in Dickson, Straw, and Dickinson (2008). At
the 2nd International Conference on Invertebrate Vision in Sweden,
2008, Andrew learned that a digitized form of the Drosophila eye map
would be useful to others, and so he created this package.

This is release 0.1, released August 9, 2008.
