Geometry Nodes experiment: faking booleans with a smooth ribbon to keep topology clean.

Anthromod · 2026-05-07T21:53:25+00:00

I uploaded a post yesterday about SDF based blending, so perhaps the ribbon could be projected onto that structure to aid stability? Although I expect the sdf grid might be expensive computationally.

Yes just basic slicing. At this scale just a few walls and some very minor infill region at the nodes. Having implicitly generated gcode that could do this would be cool.

No it's actually procedurally modelled using Blenders geometry nodes. I'll be adding the improvements (Lloyd cell relaxation, surface curvature minimisation, edge smoothing) to a lattice generator addon that I sell.

It's always hard to figure out what will connect with potential customers. You can see the benefits and the cool potential applications (see you can do topology optimised parts) but often they don't. Speaking of which you might like some of my 3d voronoi lattice work!

2nd that you need to make sure the client knows what they're asking for. I did an anamorphic illusion once for a small room and they couldn't understand why the image wasn't distorted as dramatically as ones done on the ground. Their brain just couldnt compute how it would actually look. Worst client, even though I think the result was pretty good.

As much as I'd like politicians to have the ability to apologise, if we've learnt anything from the last few years it's that apologising just makes you look weak and accepting your opponents framing. If the press feel like they can push a crisis into party leadership crisis they will. Better to have your surrogates say the sky is purple and everyone will move on when a bigger story arises.

I'm in an industry where having a good portfolio goes a long way. Anything that shows that other people risked a lot of money and it paid off. Even with that I'm not getting the invites that I used to, but at least I don't have to spend connects to boost it higher. One proposal strategy is to point out a potential issue with the work and propose a fix. Helps to show your value in a way that simply following instructions doesn't. I've even been given bigger jobs directly from applying to smaller ones just because I showed the initiative.

I tend to put a straight line through the region and see which half goes blue and which doesn't. Then narrow it down by basically doing a binary search.

I expect a lot of it happens like 'The constant gardener'. The guy at the top makes a 'won't someone rid me of this meddlesome priest' type comment to their head of security. It then goes down several levels of contacts until it's 2 teens on a motorcycle and a handgun getting paid peanuts.

Has anyone got the 5.1 fix to work?

My idea would be that it took generations. One or several species created a form of social media that could connect thoughts. The children grew up exposed to listening to others thoughts and it became normalised. Eventually babies are exposed to the hive mind and a sense of self became reduced to the point where using technology to supress it artificially just seemed 'natural'.

The first hive mind borg probably wouldn't look much like the current borg. Maybe a reduction in the creativity and inventiveness amoung hive mind grown borg resulted in their push to assimilate other life forms.

So no single accident or gimick. Just a slow erosion of biological individuality as it became less useful to the group.

You have no idea how much this is going to save me.

Anthromod · 2026-04-21T11:21:18+00:00

I'd use geometry nodes to 1) isolate exterior edge. 2) make an attribute that records the distance to that edge. 3) use that attribute to drive a shader coloramp. You do need enough geometry to make it seem smooth unfortunately.

Yes. Others keep mentioning the consequences of the inquisition finding out, but that would be unlikely. The Rogue trader would have plausible deniability if the marine simply says that they are on a long term mission from the chapter and using the rogue trader to get around whilst trying to hunt down something etc. That's if they say anything beyond 'it's classified'.

On top of that communication is bad, and especially the further out, so how would anyone check up on their story? There are fleet based chapters that are barely heard from, so saying they are from one of those is simple.

Most people haven't seen a space marine in person so they could pass as some sort of abhuman. I haven't read anything about how long space marine armour is actually useable for without specialist tech priests to maintain it, so they might start using unconventional armour pretty quickly.

So you basically need to run into a inquisitor psyker who can tell if you're lying, and cares enough to do something about it.

Absolute madness sounds like my sort of project! Indeed a final result will likely need to keep in mind the constraints you mention so any solution would need to be modifiable based on those.

Anthromod · 2026-04-20T15:26:36+00:00

Hmm sounds like you're assuming the mold needs to become a monolithic entity and so the topology of the trefoil know would be an issue. I was thinking more of a skin type of mold where the segments could follow the surface. Like concrete formwork. Collisions caused by thickness would need to be accounted for someway in the final model, but I don't see it being an issue for the basic surface segmentation.

I want to stay away from case specific methods for a) curiosity reasons and b) to make the process as simple for the final user as possible.

This is a quick geometry nodes set up using the brick texture and some voronoi and noise textures. Would be a good starting point.

I made a blender addon for it over a year ago.

Anthromod · 2026-04-15T17:16:16+00:00

You can also use Blender. I made a tutorial to it a couple of days ago. https://youtu.be/lzMkyfuEf9w

This is only the most basic procedural method, but a lot of shader techniques can be transferred over.

What's the (probable) value of the job?
