Specular reflection is beneficial. Without it, we would not have cameras or mirrors. However, diffuse reflection is central to our ability to see the world. Aside from the limited number of luminous objects, such as light bulbs and the sun, everything we see around us is visible because of...
vec3 specular = nominator / denominator; // kS is equal to Fresnel vec3 kS = F; // for energy conservation, the diffuse and specular light can't // be above 1.0 (unless the surface emits light); to preserve this // relationship the diffuse component (kD) should equal 1.0 - kS. ve...

权重拉高会使,颜色变亮。 折射,这个值可以产生高亮的区域,也可以通过粗糙度来弱化这个区域。 折射类型GGx等,对于金属好像有对应的反射类型。 做磨砂玻璃,要是折射link的话,可以通过粗糙度来做磨砂玻璃。 折射可以做玻璃,这个值越大越通透,就越像玻璃。
(e.g.Molecular Expressions). Actually, diffuse and specular reflection operate simultaneously from most materials, and evidently by quite distinct processes, in that the specular reflection typically retains the colour of the light source, while the diffuse reflection is often coloured by the material...
Using polarization measurements, the reflectance factor of 2 wheat canopies is divided into components due to specularly and diffusely reflected light. Two key angles may be predicted, the angle of the polarizer for minimum flux and the angle of incidence of sunlight specularly reflected by a ...
Specular vs. Diffuse Reflection To further investigate what occurs during diffuse reflection, consider first what happens during reflection of light and the key terms used to describe reflection. The light ray that hits the surface is called the incident ray. The imaginary line perpendicular to the...
22.3. These elements can be illuminated by either a direct or a diffuse light source. Both sources of light will provide specular and diffuse reflection. Specular reflection is defined as the reflection from the surface of the element, where the angle of incidence equals the angle of reflectance...
