An algorithmic approach to modelling the retinal receptor topography

Based on published research results on the structure of the human retina and the initial assumption of tight hexagonal packing of cones, the mean cone-distance function is derived. Disorder in the cone lattice is explained as the superposition of increasing topological distortion in the hexagonal lattice (providing a possible explanation for observed systematic lattice distortions) and local jitter of neighbor-to-neighbor distances, for which a simple statistical model is provided. These individual results are incorporated into a proposed algorithm for simulating the cone receptors' topography in 3D-space. Finally, possible software and hardware applications of the algorithmically defined retina model are briefly touched.
