Zebra striping (computer graphics)

Not to be confused with Zebra patterning.

3D diagnostic
Zebra striped surface.

Zebra striping is a diagnostic shading technique used in computer graphics to visualize curvature on smooth surfaces.[1] It is primarily used for computer aided design (CAD), where it helps checking that surfaces meet smoothly. It is a simulation of the visual effect of placing an object in a tunnel lit by parallel rows of lights, or a perfectly reflecting object in a room with striped walls. It has been implemented in a number of CAD and non-CAD products, including (but not limited to) Fusion 360, Autodesk Inventor, AutoCAD, Rhinoceros 3D, and Maya.

It can be implemented as an environment map using radiating pie wedges as the source texture.

Table zebra striping

The term is also used for tables with every other row colored to make it easier to read tables. Although Zebra striping has been used for a long time to improve readability, there is relatively little data on how much it helps.[2][3]

CSS
Zebra striping used in Nautilus.

Can be implemented using Cascading Style Sheets (CSS).
