Zebra analysis

Zebra striping is a diagnostic shading technique used in computer graphics to visualize curvature on smooth surfaces. It is primarily used for computer aided design (CAD). It is a simulation of the visual effect of placing an object in a tunnel lit by parallel rows of lights. It has been implemented in a number of commercial CAD products, including (but not limited to) Maya, Rhino, and Ashlar-Vellum.
