compound_vision_3D

This repository contains

• R package CompoundVision3D to automatically extract 3D information (number of facets, facet positions, inter-facet angles, sensitivity and acuity) of compound eyes.

Additional unpublished but existing code:

(This is part of an analysis manuscript - it is not yet decided which code will be part of the package)

• ImageJ macro language
  • crop out the left and the right eye from a CT image stacks of various sources
  • crop out head capsule and automatically scale down for landmarking if necessary
  • automatically generate surface STLs of compound eyes
• Python
  • extract compound eye surface from STLs in Blender
• R
  • import compound eye STL to R
  • extract
  • analyse the local topological differences of facet sizes and inter-facet angles
  • calculate field of view (FOV) on local differences of acuity and sensitivity within FOV
  • compare these values in an phylogenetic comparative framework
  • analyse the trade-off between acuity and sensitivity across species

This is package is still under development.
