This paper is about simulating this effect with microfacets, which are tiny microstructures on the surface of rough objects.
这篇论文主要讲用微平面模拟这个效果,微平面是粗糙物体表面上一个个小的微型结构。

Specular highlight
(重定向自Microfacet)
A specular highlight is the bright spot of light that appears on shiny objects when illuminated (for example, see image at right). Specular highlights are important in 3D computer graphics, as they provide a strong visual cue for the shape of an object and its location with respect to light sources in the scene.
