Hi Everyone. I have 2 questions. 1: I’ve used a Mobius Transformation to create spherical hexagonal grid. And I need to find a normal to some of the vertices. The idea was to make it with Cross Product + Average. Like here: [1] But as soon as I apply these script to my 3d grid its not working.…

The normal to a smooth surface is unambiguously defined, but when you have a faceted surface like this, which is not tangent continuous, there are multiple possible ways to assign a normal vector to the vertices. Which one is suitable here depends on what you want to do with it next. For example, y…

You can Transform Lines on center, on points … then uses them as normal! [image]

That is interesting way to do it. Thank you!

Yes, that would be the best way. But the idea it not to be depended on center of the sphere. In case I wound want to reuse script on different shape. I should have mentioned that…
