这次来翻译一下2013年Epics Games工程师做的分享《Real Shading in Unreal Engine 4》这篇文章,这个作为Unreal Engine向真实渲染转变的重要分析文档,对现在而言,还是有一些借鉴意义的。 Real Shading in Unreal Engine 4 by Brian Karis, Epic Games 图1:UE4的渗透者Demo 一、介绍-Introduction 大约在一年前(2012年...
2.4 Specular G EPIC经过大量评估之后选择了改动k = \alpha / 2的Schlick近似模型[2](\alpha为重新映射后的粗糙度的平方,在Disney模型中\alpha放缩为了\frac{(Roughness + 1)^2}{4}),以便更好得符合GGX。经过这个改动,Schlick模型在\alpha = 1的时候准确匹配Smith模型,并在0到1的范围内相当接近。 改动后的...
首先,我们觉得“镜面反射”是一个糟糕的参数名称,造成了很多的误解并且对于艺术家从控制镜面反射强度到粗糙度的过渡有负面影响。艺术家和图形程序一般都忘记他的范围或者当它的真正默认值是Burley的0.5(对应4%反射率)时,假设默认值为1。在实际使用镜面反射的情况,几乎完全是为了小规模的阴影。我们发现可变的折射率(IO...

Consequently, an analysis was performed to minimize this requirement by using low-quality images using Unreal Engine, which offers open-source images. Moreover, the framework developed by Microsoft, AirSim, allows simulations with a high degree of detail in the rendering [38]. 3.1. Interoperability...
