Abstract:

We propose a simple yet effective extension of ray-tracing algorithm that allows selective visibility of objects for specific rays. Typically, rays are classified as pixel, shadow, reflected and transmitted. We suggest adding a visibility mask to material descriptions, which controls how these rays interact with the material. This addition can be incorporated seamlessly into any ray-tracer and may help to generate visually interesting images.
