Surface analysis tool: Zebra

- [Instructor] In this lesson we look at…the surface analysis tool called Zebra.…This shows a reflected stripe pattern similar…to the way the environment map works,…but many modeling nerds consider the Zebra analysis…a more accurate tool due to the adjustable settings,…and the primary function of this command…is to visually evaluate surface smoothness…using a pattern reflected in the surface.…Let's zoom into these two pieces…of geometry labeled, "Not very useful."…You'll see why just in a second.…

We find the Zebra command up on the analyze menu,…go down to surface, select Zebra.…We're now going to select a couple of objects.…We can pick multiples.…Right click, and here we have the results.…So we get this flow or reflected striped environment;…however, this is not as useful as you might imagine…because we have single surfaces.…Let's briefly talk about the surface continuity;…how it applies to multiple surfaces.…

We're looking at a diagram here…that is straight from the Rhino help system.…We typically classify the continuity into G values.…
