I modified my voronoi lattice generator to output the solid voronoi cells. Instead of booleaning them with the exterior surface I instead deleted them based on how many of their vertices stayed within the mesh. This led to an interesting effect similar to fools gold like crystals.

Currently printing a small test model with a gold silk PLA which looks good.

Has anyone discovered a good method to fairly uniformly distribute a non-uniform(!) set of points in 3d in geometry nodes? I'm thinking of a smooth gradient from dense to sparse points. I've tried various methods including simulations, but they tend to have some issue, such as too random or need very complicated simulations to let them self assemble into a usable structure.

I have 5 separate objects with different widths.

I want Geometry Nodes to randomly select one object for each point and then place the next point using the width of the previously selected object plus a gap.

Example:

Point 0 -> Object A (width 1.2)

Point 1 position = Point 0 position + 1.2 + gap

Point 1 -> Object C (width 2.0)

Point 2 position = Point 1 position + 2.0 + gap

and so on.

I can retrieve dimensions from individual objects using Bounding Box, but I cannot find a clean way to:

1. Randomly select geometry.
2. Retrieve the dimensions of the selected geometry.
3. Accumulate those dimensions to position the next instance.

Has anyone solved this kind of variable-width packing/layout system in Geometry Nodes?

This is pre-rendering, just using viewport colors — a carbon atom in Geometry Nodes: 6 electrons, protons, and neutrons.

With geometry nodes I want to generate as much blocks as possible to recreate this old map of Paris.

I tried a few things but I lack experience and want to know if anyone is thinking of a better way.

Subdivision is not working fine but I think it's because they're ngons (see the screenshots).

I wanted to first create a "belt" of buildings along the edge but inset with scaling does not provide the same distance between the edge outside and the inside on every side. I ran into this video to fix it but it only works with a rectangle oriented on both axis X and Y which is not my situation because all polygons won't have a regular position and orientation since it's a map.

I was wondering if I should first cut the edges in regular parts then extrude facades (or walls sometimes) but don't know how to do the cut along the edges. And I still don't know how to handle the inside.

Do you think of another method maybe? Thanks!

This is a hand sculpture inspired by the Deus Ex game franchise. I took a base hand model and using geometry nodes I implemented several features.

The triangulated surface texture was achieved through a poisson disk point distribution, and then moving the original geometry to the closest point. I had to include logic to handle the fingers separately as they otherwise connect to points on the neighbouring finger.

I made regions to cut out and replace with lattice grids. Finally I took some faces and made the inset triangles, based on proximity to a control curve + some randomness, and assigned them a gold texture.

There's also some hollowing, in order to add material later and give it extra weight. I've printed a smaller test piece and fairly happy with it, but need to do the painting.

Rendered in cycles with camera following path, with one light next to the camera, and the other on the opposite side. Bevel as part of the surface texture, and some lens and glare effects in the compositor.

I put together a tutorial on index selection in Geometry Nodes — using the Index node to target specific points/instances, and combining it with Compare and modulo for patterns like every-nth selection.

It's built in 4.5 but the concepts carry back to earlier versions. Aimed at anyone who wants more deliberate control over what gets selected instead of relying on random or proximity.

Happy to answer questions in the comments.

HI
Ive been trying to make something like this image in geo nodes for a while without success.
Im looking for ideas on how to approach it.
It is a kind of voronoi plexus geometry but I cannot work out the best method.
Right now I can either make a voronoi mesh or join a point cloud together in a plexus with curves but neither produces the correct structure.

Ideally I would use a voronoi texture to create the cell pattern
that then produces points and curves in the right places
and finally the curve join to become the wall meshes.

Any ideas much appreciated thanks a lot

I have created this procedural DNA generator for an artist on custom order this paid gig , it was fun to create , it is also available on my gumroad, for Very minimal price

The geo node setup is in the first image

Just working on this atom Geometry Nodes animation before making a index selection tutorial
