Real-time glossy reflections on planar surfaces

Abstract

In this paper we concentrate on an optical effect well-suited for architectural or game-related renderings: glossy reflections on planar surfaces. We demonstrate a physically reasonable approximation of glossy reflections at slightly imperfect reflecting surfaces --- e.g. most floors --- that can be implemented at minimal performance penalty when compared to perfect reflections. An evaluation of our implementation using only standard graphic API functions in OpenGL 1.2 concludes the paper.
