view-dependent lighting

Reflections and specular highlights are examples of view-dependent lighting – their location and shape on an object’s surface changes depending on the viewer’s position relative to the reflective object. View-dependent lighting is very subtle to observe, yet is a critical cue in VR for true immersion, without these interactive reflections and highlights, the content can feel lifeless. In both CG and live action VR, only true volumetric techniques like Light Field video can accurately reproduce these critical view-dependent lighting effects.
