Ray tracing models follow light from the source to the surface of interest (forward ray tracing) or from the surface of interest back to the source (reverse ray tracing). These models are typically based on a Monte Carlo approach that simulates hundreds or thousands of different rays and uses optical physics to predict how each ray interacts at each surface in the model domain.
Our project is looking into two different models:
- RADIANCE – a reverse ray tracing application
- COMSOL Ray Optics – a forward ray tracing application
