Incoherent Addition to Generalize Depolarization in Light Scattering Models
Models for polarized light scattering are relevant for creating virtual reality scenes. To get a “real” looking model, the light scattering on the model needs to be simulated correctly to get a realistic model. The polarimetry of objects is measured in the lab, fit to a model, and this model is used to simulate the polarized light scattering...
