Tarini M., Cignoni P., Rocchini C., Scopigno R. Real time, Accurate, Multi-Featured Rendering of Bump Mapped Surfaces. Technical report, 2000.
We present a new technique to render in real time objects which have part of their high frequency geometric detail encoded in bump maps. It is based on the quantization of normal-maps, and achieves excellent result both in rendering time and rendering quality, with respect to other alternative methods. The method proposed also allows to add many interesting visual effects, even for object with large bumb maps, including non-realistic ren-dering, chrome effects, shading under multiple lights, rendering of different materials within a single object, specular reflections and others. Moreover, the implementation of the method can be very easy.
