[vtkusers] Zebra shader to visualise continuity of surfaces

[Jonathan Borduas]

Hello,

Is there a zebra shader in VTK ? Many surfacing software such as Rhino, Alias and Fusion360 incorporate this Zebra shader to show the continuity (G0,G1,G2..) of the surface between different patchs:

This allows a designer to verify that the aesthetics of the blend between two surfaces. See attached pictures zebra.png.

Best regards,
