Do you really know the difference between roughness and waviness?

If we want to understand and describe surface texture, we need to understand how to separate roughness from waviness. We often do this by applying a Gaussian filter. In this short video we show you how that process works. We’ll also show you the importance of the “filter cutoff wavelength,” where we choose to separate roughness from waviness. This cutoff has a huge impact on the values of our surface roughness parameters!
