Separate eye rotation centers are now defined for azimuthal and elevational eye movements, incorporating the values from by Fry & Hill 1962 and 1963.
Rotation centers adjusted by posterior chamber size
Improvement to the cornea model and correction of an error in asphericity specification
Model eye now has parameters for the canine eye
We now estimate camera translation and scaling parameters for eye rotation center. In practice, camera depth should be set by estimation from the maximal observed iris diameter
Scene parameter search now minimizes shape and area errors in ellipse fitting
