'''Zebra analysis''', or '''zebra striping''', is a diagnostic shading technique used in computer graphics to visualize curvature on smooth surfaces.<ref>Kenton Fleming, Computer Aided Engineering: An Undergraduate course in computer aided design and analysis for mechanical engineering technology, Southern Polytechnic State University. http://www.intellectbase.org/e_publications/jagr/JAGR_Volume_2_Issue_2.pdf {{Webarchive|url=https://web.archive.org/web/20161229154041/http://www.intellectbase.org/e_publications/jagr/JAGR_Volume_2_Issue_2.pdf |date=2016-12-29 }}</ref> 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.
== Implementation == Zebra striping has been implemented in a number of CAD and non-CAD products, including (but not limited to) Fusion 360,<ref>{{Cite web |title=Zebra Analysis reference |url=https://help.autodesk.com/view/fusion360/ENU/?guid=GUID-650F81AF-3744-460B-87DE-F2082E86FE5C |access-date=2024-04-10 |website=Fusion Help}}</ref> Autodesk Inventor,<ref>{{Cite web |title=To Analyze Smoothness |url=https://help.autodesk.com/view/INVNTOR/2023/ENU/?guid=GUID-E4036468-EACB-463B-961F-B33765C5D699 |access-date=2024-04-10 |website=Autodesk Inventor 2023}}</ref> AutoCAD,<ref>{{Cite web |title=About Analyzing Surface Continuity With Zebra Analysis |url=https://help.autodesk.com/view/ACD/2024/ENU/?guid=GUID-82E5989F-C943-49A6-A6C6-834B81CC203B |access-date=2024-04-10 |website=Autodesk AutoCAD 2024}}</ref> Rhinoceros 3D,<ref>{{Cite web |title=Zebra {{!}} Rhino 3-D modeling |url=https://docs.mcneel.com/rhino/6/help/en-us/commands/zebra.htm |access-date=2024-04-10 |website=docs.mcneel.com}}</ref> Plasticity, and SolidWorks.<ref>{{Cite web |title=Zebra Stripes - 2020 - SOLIDWORKS Help |url=https://help.solidworks.com/2020/English/SolidWorks/sldworks/c_zebra_stripes.htm |access-date=2024-04-10 |website=help.solidworks.com}}</ref> It can be implemented as an environment map using radiating pie wedges as the source texture.
