Does somebody know a creative work around to align the zebra light to, lets say to the Z vector, and rotate the view without changing the zebra light direction? VSR-Tools are able to do the trick. Any idea to do it without?
Thank you in advance,
Norbert.
Not sure if this does the trick, but how about a display mode which used a single material for all objects, and that material has a vertical zebra stripe set as its environment. Quick display mode attached.

If you set the texture as environment it will behave just like the native Rhino zebra analysis (that means it will change rotating the object)
You will need to set it as the colour texture to remain static.
Just create a zebra material (using a horizontal or vertical striped texture you find on the internet or create yourself) and apply it as needed.
You might need to adjust the texture mapping of your model though.
Cheers, Norbert
You helped me a lot in bringing me to the right idea. Thank you!
Nevertheless your proposal doesn’t meet exactly what I wanted, because the stripe pattern is mapped to the surface. Pulling a Ctrl-Pt will change the mapping to fit to bounds of the surface.
Needed is a directional projection of a stripe pattern, supported by the freedom to choose a direction and stripe width.
The attached model will serve that purpose. Basically it consists of stripe shaped surfaces in front of a directional light using the rendering display mode incl. enabled shadows.
But still it “takes the long way around”. There is the question to simplify this?
Enjoy,
Norbert.

Hello
I don’t know if it interest still someone but I will add some components in Nautilus to make a texture representing Zebra stripes. At the moment stripes are on an infinite cylinder and I will surely add a Stripped dome like in Rhino.
Discussion on the subject here
Thank you for asking and no, my interests changed since then. Just to clarify the background of this particular topic: The strak/surfacing (ICEMsurf or former VSR Tools for Rhino) community is using zebra lights for live analyzing of surfaces in a different way than in Rhino possible. The stripes are fixed to the object, even if you change the view. The stripes only change if you drag a CV or otherwise change the geometry. Mathematically, these are Isophotes of a light source which is bound to the object and not to the position of the view. May be that helps. I don’t want to mess up your original topic with that stuff.
