头发为计算机图形场景增添了令人信服的丰富性。本文描述了在当前PC图形硬件上实时光照和渲染短发的技术。绘制毛发的详细等级表达跨越了从使用程序生成的Alpha混合线的特写镜头到使用体积纹理的中视图和远视图，再到使用各向异性纹理贴图渲染的远视图的查看距离。具有柔和边缘阴影的实时照明在各详细等级表达中是一致的。
Hair adds compelling richness to computer graphics scenes. This paper describes techniques for lighting and rendering short hair in real-time on current PC graphics hardware. Level-of-detail representations for drawing fur span the viewing distance from close-ups using procedurally generated alpha-blended lines, to mid and far views using volumetric textures, and on to distant views using anisotropic texture map rendering. Real-time lighting with soft-edged shadows is consistent across the level-of-detail representations.
