#geometrynodes ForEachElement node will make it so much easier to separate the outer and inner corners with just few nodes. #b3d

Nice one. But, shouldn't the red stripe thing be in inside corner ? ;) Anteeksi :)

Nice!!! How??

How to judge the inside and outside of the corner？

The base curve is split to Island, expanded and turned into the outer curves. I evaluate the curve lenght per each Island. The outer curve is always longer unless theres S-shaped situation. Could also resample and evaluate amount of points/indexes.

I once tried setting a curve's tilt based on the curvature. How did you manage to use the curvature threshold?

I use Sample Curve node to sample 3 positions thought out the curve. 1 earlier, 1 in the middle, 1 later. And compare the vector between points 0to1 and 1to2 with dotproduct. With the same method you can figure out the direction of the curve since the outcome is either + or -

Awesome work!

You are genius.

Genious!

Ooh this is so close to what I bugged you about a while back 😍 Does it also use less polygons for the straight sections?

Oh did you😄 there's so much things to answer to I tempt to forget. But thanks for the good idea ! I can also reasample each somewhat straight section separately with average curvature value 🤔🤩
