11. 2D vs 3D (Areal) Texture


Is a 3D (areal) texture measurement “better” than a 2D (profile) measurement? There are strong opinions on both sides. But the truth is that there may be some common ground. In fact, there are cases in which each type of measurement may be the right choice. In this video we discuss the properties of 2D vs areal (3D) measurement systems. We talk about how the two are related and we show where one may be preferable over the other depending on the application.
