procedural-eye
An open procedural eye in three.js by Gianluca Lomarco was the main structural reference for the realism pass: what a believable eye is made of, part by part. It was studied, not copied.
What it taught
That realism in an eye is a list. Skin relief, the wet rim, vessels in the white, the depth of the iris, the way lashes clump. The realism pass went through that list one part at a time and asked of each: take it, improve it, or leave it.
How it was used
The repository carries no licence, so no code or texture came across. The parts were rebuilt here from anatomy, from the papers listed on the eye's page, and from a photograph of my own eye.
It is on this map because a lineage that hides its references is not one.
