Hello folks, I found this python Safe Inset (Blender Addon) and tried to replicate the basic logic with Kangaroo, I’m not sure if it’s the right way to go. The main idea is to work with a HIGH offset distance and keep all edges with a least a minimum length to finally quadmesh it. I started with …

It’s an interesting idea. Thanks for sharing. I’m not sure physics based is the easiest way to approach this. An iterative approach where edges are moving in gradually while preventing them crossing over makes some sense though. It seems a key and tricky part of it is handling the topological cha…

Here’s a screen capture from 2021… It shows a Kangaroo based optimization of self intersections on mesh offsets inside a climbing hold mold. I cannot share the model and definition. It is possible with Kangaroo but I’d say it’s complicated :slight_smile: Anyway, thank you @DanielPiker for ma…

[image] Daniel Piker: reaching zero length and straight edges developing kinks when hit by a point from the other side. Thank you for the input. Actually, this is what I expect when there are no kinks and all are quad-faces. When @laurent_delrieu put the comparison just noticed the ngons fac…

I don’t understand the purpose of safe inset , i tried it before in Blender when i searched for straight skeleton solution [image] [image]

I found a goal for direction alignment without reversal I wrote a while back: direction_no_reverse_goal.gh (11.1 KB) (That aligns with the input lines starting direction. Let me know if you need it to accept a different vector, as it would be easy to modify) I’m also curious about what the use ca…

I’m joinging this party late, sorry. [image] Thomas Evans: I prefer this only quad faces version. I agree. [image] anon39580149: I don’t understand the purpose of safe inset Same here. How/when is this useful? I understand creating a new rows/loop of quad faces that have the same w…

Here an attempt. Iterative while checking for collisions… [aggressiveinset] AggressiveInset V0.11.gh (13.7 KB) Input points will make a closed polyline Input points must create a polyline that is flat on XY plane, counterclockwise, with no starting self-intersections. Gif seems good but it’s ac…

[image] Riccardo Majewski: Here an attempt. Awesome @maje90 really nice! better imposibble, don’t be modest! :grinning: how could it avoid concave quads, a triangle with 4 vertices would be better (every bisector projection could check if it intersects first with the adjacent bisector proje…

[image] Thomas Evans: how could it avoid concave quads Concave quads are expected. Or, at least, it’s how I interpreted the “rules” by just looking at the videos you posted. Watching them again, actually it never happens, but maybe because the used shape are “lucky”… [image] Thomas Evans…

@anon39580149 has done Wizard which gives results very near of what you want. In Green Wizard Output.

perhaps he could tweak his code

I also did something similar with Sand Dunes
