:freecad: #FreeCAD's new Zebra Tool actually has 3 modes:
1) #Zebra🦓 ;
2) #Rainbow🌈 ;
3) #Isophotes🌔.
Zebra Tool main purpose is to analyze #NURBS surface smoothness (curvature) and discover rough edges visually comparing representation of stripes mapped onto surface.
📝 Now this tool also could be used for #Mold Analysis to visualize #InjectionMolding Core/Cavity Split: https://forum.freecad.org/viewtopic.php?p=694161#p694161
Sample model (see attachment): https://forum.freecad.org/viewtopic.php?p=656355#p656355

📝 Two days ago, during discussion with @pafurijaz (thread: https://fosstodon.org/@app4soft/110717081395359297), I've found interesting resources on Zebra stripe (#Isophotes) shading implementations in OpenGL & sent it to developers of #FreeCAD:freecad: #Curves Workbench.
Today ''Chris_G' presented screens of an upgrade for #Zebra🦓 Tool — actual texture-based shading would be replaced with a 🆕 fragment shader: https://forum.freecad.org/viewtopic.php?p=693526#p693526
My #nocode contribution was just to google useful resources.
