The simulated light distribution for each individual source pixel is used during the driving simulation. The masked region shown on the aiming wall is not entirely dark anymore. Instead, you can see some illumination caused by Fresnel reflections, aberrations, stray light effects, ghost images from your optical system, impact of coatings, etc. | Synopsys
