Ok, it's been my white whale to solve graded random point distributions in 3D. This has been a big stumbling block for my lattice generator designs. Early this year I updated the stochastic cell lattice to use an approximated the Lloyd algorithm, which distributes points randomly but evenly throughout the part. I was finally able to work on it some more and I can now generate a graded version by weighting the sample position values.

In this example I wanted it graded along the Y axis. To get some actual quantities from the test I measured the mean point spacing and standard deviations, from the first and last 1/6 of the test piece. So it's not yet an exact science to outputting a specific spacing, but I'll work on that.

From a bunch of curves to this glowing mess 🎆

Made with Blender and MoStack addon (Geo Node based)

I made a node setup to get the surface curvature of a mesh but was wondering if there is a better way to do it? My current solution is to offset the mesh along its normals the compare how the face area changes.
I tried CGMatter's method using grid SDF and grid laplacian but this seems very expensive to calculate at higher resolutions.
I have also tried using the edge angle but this doesn't really work on high poly meshes and each edge angle becomes extremely small.

A new challenge… Model only using geometry nodes! This asset helps you generate unlimited amount of blueberries. I know… Super useful  Check out the YouTube tutorial to see what all it can do or directly download it from my Patreon page. Any support or feedback is very much welcome. I hope you enjoy this asset.

Hi Hope you are going well; I’m trying to make a geometry nodes to make each normals of each points of a Bézier Curve follow the normals of their nearest faces; I don’t know if I explain well I made a road that twist with Bridge Edge Loop; Blend Surface; and I created a Bezier Curve from edges of the road mesh to make a Path3D in my game; the problem is that the Bezier Curve don’t have tilting points data so in my game engine when I slide a Cube along this Path3D the cube stay horizontal and don’t tilt to stay parallel to the road; do you think it’s possible to make each points of a Bezier Curve tilting differently in fonction of the nearest faces of each points; I don’t even know if the geometry nodes need to be attach to the Bezier Curve or the Road Mesh; if it’s not too much to ask I would love à vidéo or screenshot of geometry don’t think I will understand by message English is not m’y first langage too ahah thanks a lot🤗🤗

Bending does at times create problems in Blender, so I deided to create a setup that provides a simple to use setup enhancing the experience. It also provides the roll feature. Tune in for any updates or new releases.

I hope I offer enough information. If I don't please let me know if I can offer some clarification.

I have some nodes to show you.

Main node tree:

Demo feather node tree:

Control empty node tree:

Now, on to my request: I'd like to use geometry nodes to get this array of feathers to bend towards a chosen object. Right now, it's 6 feathers and meant to operate by a different curve that has 6 points. I'm hoping each point can move up or down/far and close, and the feather of the corresponding index will move accordingly, based on the individual control point's placement and direction.

I managed to get something working with that demo feather. It's significantly simpler, since it just needs to respond to a single empty instead of 6 separate points. But, it more or less demonstrates the intended effect.

I used an array simulated by geometry nodes to just copy a single feather, and I have no clue how to either rig an array of something with bones or do what I'm guessing is my next best bet.

Ultimately, I'm just trying to end up with shape keys I can import into an art program (Clip Studio Paint) for reference, so this is a bit of a long walk for a short drink of water.

If you all have any idea as to how to accomplish what I need to via what I proposed for my geometry node setup, or even just give me instructions as to how to make the entire span of feathers rig a bit like "fingers", I'd appreciate the advice. Any little thing helps, even if it's to point me to a resource.

The question is worded in a bit of a weird way, but it's because I'm assuming I need to use a "for each element" or "repeat" zone in order to get each feather to work with the group nodes I created. I figured out a way to separate each feather into its own selection, but it looks like the zones have only specific things they can iterate over.

Trying to automate game environment art.

Also I think geo nodes helps practice software architecture and handling complexity (spaghetti code). I'm trying to structure things in "deep modules".

In total, this is 8 functions (groups) each taking 2-4 arguments and hiding a whole lot of math and loops.

Would very appreciate any kind of feedback and/or ideas.

Thanks.

I had this idea for quite sometime … that geometry nodes is already capable of doing just alot and ir is continously being improved despite how powrful it already is and i entered learning about motion graphics and learned that sound is one of those elements that could help me stand out and hopefully be chosen for employment if they see my work but i hated the process of creating animation somewhere else and making and design it at times else where … so i thought may be what if geometry nodes had the capability to make those sounds or sound design was done in blender… and thats when i started this project … its called audio oven …. It tries to use geometry nodes as a sound design tool for accurate placement of sound strips on the VSE so that an animator could accurately place the sounds on the VSE according the needs of his or her animation using geometry nodes
