Digital Tutors 出品的Shader Recipes Diffraction Grating in Maya 视频教程. 该教程讲解了我们将学习如何模拟一个衍射光栅光散射的外表，可以看到CD或DVD表面.
Diffraction grating (衍射光栅):
利用光的多狭缝衍射效应进行色散的光栅元件，它能使光波衍射而产生大量光束，利用这些光束的干涉形成光谱。 一种由密集﹑等间距平行刻线构成的非常重要的光学器件。分反射和透射两大类。它利用多缝衍射和干涉作用﹐将射到光栅上的光束按波长的不同进行色散﹐再经成像镜聚焦而形成光谱。天文仪器中应用较多的是反射光栅﹐它的基底是低膨胀系数的玻璃或熔石英﹐上面镀铝﹐然后把平行线刻在铝膜上。
教程时长: 30分钟
使用的软件: Maya
In this series of lessons we will learn how to simulate the light-scattering appearance of a diffraction grating, which can be seen when looking at the surface of a CD or a DVD.
While Maya may not have the capability to simulate a true diffraction grating, we can create a shading network that can very closely mimic the effect. We will learn how to use ramps, layered shaders, anisotropic materials, texture placement nodes, and specular lights to create a realistic rendered CD.
