BEX Tutorial 16 - Surface Roughness from 3D STL Data - Part 2 of 2 - 3D S Series Parameters

This is the second of two videos where we show how to analyse surface roughness and wear from 3D STL (point cloud) X-ray CT data. In this part we show how to isolate and extract the S series of roughness parameters (Sa, Sq) using 3D Gaussian Filtering to evaluate surface texture changes caused by erosive wear.
