Polarization and birefringency considerations in rendering
David Conrad Tannenbaum, P. M. Tannenbaum, Michael J. Wozny · 1994
In this work we render non-opaque anisotropic media. A mathematical formalism is described in which polarization effects resulting from light/material interactions are represented as transformation matrices.When applying the matrices a skewing is performed to ensure that like reference coordinates are used. The intensity and direction of an extraordinary ray is computed.
