Title:

    Plausible Iris Caustics and Limbal Arc Rendering

Presenter(s):



Abstract:


    In this paper, we apply anterior segment tomography measurements from contact lens research to photorealistic eye rendering. We improve on existing analytic rendering models by including a conical extension to the usual ellipsoidal corneal surface and we demonstrate the advantage of using a more accurate iris depth. We also introduce a practical method for automatically rendering the limbal arc as an intrinsic part of sclerotic scattering.
