一个实时硬件渲染器的光反射图像与粗糙表面的属性已被开发为嵌入在一个单一的芯片的图形功能之一。渲染器包括Bui-Tuong Phong（1975）和R.L. Cook & K.E. Torrance（1982）基于经验、物理或波动理论的模型。为了简化硬件结构，避免矢量归一化，每个多边形插值，表面法线，光源方向，视图方向和凹凸法线表示为一个角度的形式。渲染器在0.8 ns（12.5亿像素）内生成粗糙表面的反射图像。本文介绍了新的基于硬件的算法和架构。
A real-time hardware renderer for light-reflected images with rough surface properties has been developed as one of the graphics functions embedded within a single chip. The renderer comprises Bui-Tuong Phong's (1975) and R.L. Cook & K.E. Torrance's (1982) models on the basis of empirical, physical or wave theory. To simplify the hardware architecture and to avoid vector normalization, every polygon interpolation, surface normal, light-source direction, view direction and bump normal are represented by an angular form. The renderer produces reflective images of rough surfaces within 0.8 ns (1.25 billion pixels). This paper describes the new hardware-based algorithms and architectures.
