Tutorial – Analysis of complex surfaces with Mountains® 8.0 by François Blateyron, Digital Surf

Description: Exploration of specific tools of MountainsMap® for the analysis of structured surfaces and freeform surfaces, with the first preview of new tools from the forthcoming new version 8. Special focus will be put on the automatic detection and characterization of periodical features and on the challenges raised by complex surfaces compared to classical surfaces. With a discussion on the future of surface texture on freeform surfaces.
