In per-pixel lighting, each pixel color is computed individually (as on the left. ) You can see that even when I use low-poly sphere for this example, the lighting still makes it look round.

在逐像素过程中，每个像素的颜色值都是单独计算的（如左图所示）。 就算我们对左图的轮廓使用低模效果，中央光照效果依然看起来非常圆润。

The paper focuses the GPU based real-time rendering technologies. It involves the following parts: per-pixel lighting, real-time shadow, glass and velvet texture rendering, and skinned mesh rendering.

逐像素光照计算、实时阴影、材质与丝绸材质的渲染及蒙皮网格体的渲染。

Per-pixel dynamic lighting will add significant rendering overhead to every affected pixel and can lead to objects being rendered in multiple passes.

逐像素的动态光照将对每个受影响的像素增加显著的计算开销，并可能导致物体会被渲染多次。

What's more, Nikon's Scene Recognition system draws upon the 420-pixel RGB color 3D Matrix Meter for outstanding exposures under a variety of lighting conditions by integrating a database of tens of thousands of sample images.
