Real-Time Shadow Maps on Mainstream Graphics Hardware


Abstract

This white paper describes techniques to generate shadows on mainstream graphics hardware in realtime. Shadows make a 3D scene more realistic and the realism is increased by the use of floating-point textures in shadow maps. This paper describes how shadow maps can be generated in graphics hardware that does not support floating point textures and those that do.

  • Fast Color Conversion Using Streaming SIMD Extensions and MMXT Technology

    Datatype color conversions are a common requirement in 3-D application pipelines. In a simple lighting scheme, these conversions happen at least once per color channel, red, green, blue (R, G, B) per vertex, and in a more realistic lighting scheme, such values are often calculated multiple times for different light components. Color conversion from single-precision floating point values to integer values is typically done by using simple casts, for example intvalR = (int)fpvalR; where intval is an integer and fpval a singleprecision floating point number.
