Abstract
The present invention extends to methods, systems, and computer program products for representing polarized light in computer models. A rendering pipeline receives three dimensional modeling data (e.g., geometric primitives) for rendering a two dimensional image are received. The modeling data includes data representing a light source The light energy from the simulated transmission of particles at each pixel of the two dimensional image is calculated for any particles transmitted in an adjoint direction from a specified view point back to the light source. The light energies from each pixel are summed to calculate the total light energy present at the specified view point. The total light energy can be forwarded to other modules in rendering pipeline to more accurately render the two dimensional image, such as, for example, representing polarized light in the two dimensional image.
