FlyView

Draws one 3D scene twice, once the way a person sees it and once the way a fly does, where every viewing direction comes from a real Mi1 cell in MaleCNS v1.0: 886 medulla columns for the left eye and 887 for the right. The direction map ships as a 100 KB file, so the viewer needs only Python and a browser. The write-up separates what the data gives, which is the order of the columns, from what is imposed from published anatomy, such as the half-sphere field and the 150-degree divergence between the optical axes, and makes every imposed number an environment variable.
