Abstract

In this paper we present a novel high-quality rendering system for Augmented Reality (AR). We study ray-tracing based rendering techniques in AR with the goal of achieving real-time performance and improving visual quality as well as visual coherence between real and virtual objects in a final composited image. A number of realistic and physically correct rendering effects are demonstrated, that have not been presented in real-time AR environments before. Examples are high-quality specular effects such as caustics, refraction, reflection, together with a depth of field effect and anti-aliasing.
