Surface curvature analysis, like "zebra" in Rhino

Hi there,

does anybody know of a way to generate the zebra stripes pattern in grasshopper that is available in Rhino (Analyze - Surface - Zebra)?

I searched RhinoCommon, but that didn not help me very much. I found "VisualAnalysisMode Class", but I could not figure out how to use it...

What I would like to do is:

- I have a brep in grasshopper (with multiple faces)
- I would like to display this with zerbra stripes as Rhino does it to visualize the surface curvature

Any ideas?

Best regards
Stefan

The more detailed the mesh, the higher the resolution of the stripes. You can up the number of minimum mesh quads in the custom meshing settings.

Thank you!

The VB component works very well for me!

Hi David,

That little VB Script is really awesome. Too bad I just suck at VB and cannot figure out how to apply it to a Mesh (instead for a Brep). I would appreciate hints or advises!
Thanks,

Fab
