By IOR (Fresnel reflections) - USES a fixed reflectioncurve based on the Angle of view and its strength is controlled by the material's index of refraction.
依照折射率(菲涅耳反射)使用一个依据观察角度计算的反射折射，其数值大小依据物质折射率。

Due to the wavelength dependence and finite spectral width of the reflectioncurve, the reflectivity which takes effect is generally higher than the minimum reflectivity claimed.
The equations of caustic curve and its initial curve for a crack illuminated by an oblique incident light beam in reflection arrangement were deduced using the space analytic geometry method.
