Hey, sorry, I communicated unclearly.
I understand that Normals of adjacent faces get interpolated when using Smooth Shading instead of Flat shading.
While trying to explain to you better what my problem is (or rather was), I think I understood what you were trying to tell me. And I am pretty sure I now also understood the thing I could not wrap my brain around. I’m still having problems on understanding what the exact math is behind it but I’ll figure that out.
Thanks for your Help, Martin!
