Precision model for crosstalk calculation in lenticular 3D displays
For curved lenses, surface normal varies at each point. This affects refraction angle significantly compared to flat surfaces.
Each ray refracts according to the surface normal at its intersection point with the curved lens.
Rays hitting lens edges bend more than center rays, causing focal point spread and crosstalk.
Lens radius directly affects ray paths. Larger radius = less curvature = less refraction power.
