Beam Casting Implicit Surfaces on the GPU with Interval Arithmetic

Abstract

Abstract-We present a GPU-based beam-casting method for rendering implicit surfaces in real time with anti-aliasing. We use interval arithmetic to model the beams and to detect their intersections with the surface. We show how beams can be used to quickly discard large empty regions in the image, thus leading to a fast adaptive subdivision method.

Low-Latency Rendering With Dataflow Architectures

“…The intervals in this case would be the bounds of the ray packet. Alternatively the area of the packet could be described as a primitive, and things like geometric intersection tests used in the place of ray intersection tests [107,65].…”
