“…Some researchers [14,26,31] built or proposed dedicated graphics hardware to implement bump maps, while others [25] use multipass techniques to realize bump maps with traditional graphics hardware. In contrast to bump maps, which define the variation of the surface normal in terms of a bump height, normal maps directly specify the direction of the surface normal.…”

With fast 3D graphics becoming more and more available even on low end platforms, the focus in hardware-accelerated rendering is beginning to shift towards higher quality rendering and additional functionality instead of simply higher performance implementations based on the traditional graphics pipeline.In this paper we present techniques for realistic shading and lighting using computer graphics hardware. In particular, we discuss multipass methods for high quality local illumination using physically-based reflection models, as well as techniques for the interactive visualization of non-diffuse global illumination solutions. These results are then combined with normal mapping for increasing the visual complexity of rendered images.Although the techniques presented in this paper work at interactive frame rates on contemporary graphics hardware, we also discuss some modifications of the rendering pipeline that help to further improve both performance and quality of the proposed methods.
