Iris rendering Aaron Lefohn, Richard Caruso, Erik Reinhard, Brian Budge and Peter Shirley

Human irises acquire their beauty through a layered and highly complex structure that is difficult to model and render with conventional techniques. Capturing their complexity could be achieved with image-based techniques, but this would require a fairly elaborate set-up. Procedural models could be devised, but these would have to be based on descriptions of the iris that are currently unavailable. Instead, we present an approach that uses domain knowledge from the field of ocular prosthetics. We translate the methodology employed by ocularists into a simple and effective Lego-like toolkit which can be used to create and render realistic looking irises.
