Need some help to create chisel wood textures in grasshopper

[stratoudakis]

I am kind new in Grasshopper and mostly I try to use it as as a tool to create and analyse woodcarving designs and shapes/ forms.
I would love if some have some tips or a tutorial how we could recreate a chisel gauge wood texture as in the photos bellow.

Idea is to test in grasshopper ideas before I finally carving them with hand tools or use 3d prints for copper molds.

I was thinking that maybe a good idea would be to use attractor points to control the size direction and symmetry.

Thank you and stay safe in those strange times

What would be the best way to patch this?

I have created several polylines based on a voronoi pattern. Each segment has a slight concavity to it to yield a scalloped form. However, I’m not sure what the best manner would be to build a surface between all of these polylines. Bonus points if you can also recommend a way to add a fillet to each arched edge so soften the form. I appreciate any input! [23_capture_01] 2018.08.23_mcneel_forum.gh (11.8 KB)

Final Baking and Union Difficulties

Thanks to Joseph Oster, Aris Nikolopoulos, and Lauren Delrieu for all the help on my Closed Curve and Boundary Post. I have a program that works all but the ability to Bake and Union which are the last 2 steps. At one point the Extrusion with Spheres portion would bake but when i attempted to Boolean Add in Rhino it would not add. Now i cannot even bake the Extrusion. I went through 12 pages of Bake problems in GH Forum but found nothing to help. I Flattened the data going from the extrusio…

Procedural textures, noises, rocks

[stratoudakis]

Thanks for the help, I have “play” with the voronoi pattern but my knowledge in Grasshopper is still basic I think. As in the photos a voronai pattern that is randomized in shape in a surface and attractors to control the size / direction of the texture would be ideal. again thanks and I will keep trying.

I thought it would be fun to try and use Anenome to take chisel strokes of material from a mesh.

[EDIT: I don’t know how to show a GIF file here]

I’m not sure if it could handle a high enough resolution to get the effect you want and the chisel path strategy needs some work but I liked the idea.

I use a preview from Intralattice which I haven’t included in this file.

I have deside to try with a light script using Voronoi and a curve attractor to control the Voronoi cells. But here I am stuck and 100% the script is a mess. I liked to split the cells in to groups so I the future the script is easy adapted. not close to carving chisel, maybe some random needed, but anyway I just like to share and hear about solutions and suggestions.

Hello
I didn’t look at your script but I emailed you that I posted a solution. Did you look at it? Link on this page!!

Did you see @laurent_delrieu 's post in the gallery?

Mesh Carving

[stratoudakis]

Hi Laurent. Thanks you so for the time and help , I have read the post and try to adjust the script to my needs.
I have hard time to adapt it to a rectangular mesh /face and the Dendro plugin works not on my Mac.
your solution would be great if I could get it working for my especially the last one on your post where
it is more random and more “non chiseled” parts.

[laurent_delrieu]

OK I am happy not to have a Mac.

If you want more traditional thing use Daniel Piker solution. Link of the discussion already given and here the more precise link to Daniel tool.

What would be the best way to patch this?

It’s true this approach relies on using spheres of the same size (otherwise you’d need to calculate a weighted Voronoi diagram). The size of the Voronoi cells doesn’t need to be linked to sphere radius though - that’s just a result of how his points are distributed. Talking of distribution, a suggestion for one way of getting a nicer distribution here would be to apply a few iterations of Lloyd’s algorithm (repeatedly moving the Voronoi points to their cell centroids). Making the cells more cen…
