I don't know why the "TriRemesh" command has an error

I’m copying this YouTube video and I don’t know why I get an error while imitating Triremsh commands that come out around 2 minutes and 50 seconds. I made the curve here and filled it out, and I copied the rest of the algorithms just like the video, but there is no problem with the triremesh command in the video, but I keep getting errors. If you know of a solution for this phenomenon, please help me.

Interesting.
Your cubes share faces, edges and vertices.
When you cull the cubes, you randomly leave some pairs of cubes sharing only a single edge or a single vertex:
single vertex shared:
2023-09-16 12_50_37-Window

single edge shared:
2023-09-16 12_49_59-Window
aka “non-manifold”
2023-09-16 12_51_53-Window

This will prevent you from having a valid mesh for smoothing and other processes.


Simple cheap solution:
bake your cubes and manually remove the wrong ones
OR
deform your cubes edges such the wrong edge or vertex sharing no longer happens


What you are trying to do, culling cells/boxes (or voxels) by distance is what is called “iso surfacing”.
There was a plugin called “Millipede” but I think it’s no longer accessible.
(Maybe Dendro has iso surfacing?)

See Isosurfaces / Signed Distance Fields

The part you checked is the stage after the Triremesh Comfort is activated, but I don’t work because Triremesh has an error. What’s the problem…?

As the video says, you have two solutions. One is Triremesh, the other is mine.

If Triremesh fails(@maje90 explained), you need to choose the second solution.

I’m sorry but I’m Korean, so I don’t know exactly what you’re saying even if I translate it, and it still doesn’t work on my computer. If you don’t mind, can I get a grashopper algorithm? I’m in a big hurry

Do you mean to connect the checked part to the “Weaverbird’s Laplacian smoothing” comfort instead of triremesh? Does that make a truss? If you don’t mind, can I get the grasshopper algorithm you helped me with? I’m Korean, so I don’t fully understand the explanation of the video… I’m sorry

@maje90가 올린 이미지 형태로 Mesh가 만들어지면 나쁜? Mesh로 되어 triremesh가 실패합니다.
튜토리얼에서 말하듯이 이런 경우에 Subdivision방식을 취해야 합니다. Triremesh뒤 Subd를 거는 것이 아니고.
