Eye Model

Overview

My most current work is on a detailed digital model of modern display devices (direct view and projected) and the optical properties of the human eye. My mode of the human eye, in addition to traditional conic surface representations of the cornea, lens, and spherical shape of the retina, includes a custom model of all five million cones of the retina. Using a full diffraction optics model, and simulating one quanta (photon) at a time, I have simulated the photon absorbency of cones when the simulated eye is viewing a simulated digital pixel display device. This system has applications in building better display pipelines as well as display devices, and for better understanding of the mechanisms of the human eye.

Papers

This is the (unpublished) long (14 page) version combining my SIGGRAPH 2005 paper and sketch (originals further below) with some additional text and figures that had been cut due to length restrictions. Also, several of the figures are larger. If I were a research institute, this would be the “technical report” expanded version of the paper. (The small and large pdf files are more and less compressed versions of the otherwise identical papers.)

JPEG Image

The size and scale of all five million cones of the human eye are hard visualize. To help, below is a link to a page containing a link to an 8K by 8K jpeg image, along with directions of how to best view the image.

PDF Image

The same data can also be viewed as a pdf file. Here each of the cones is represented as an polygon, and labeled dashed circles give visual eccentricity again. Below is a link to a page describing this pdf image, as well as a link to the pdf file.

Videos

Below are several short wmv video files of the eye model in operation as presented in the talks given on the paper. (Eventually there will be a link here to a high quality quicktime format version of all the videos appended and with a sound track as is on the ACM SIGGRAPH 2005 papers DVD video, but at high quality it is a gigabyte in size!)
