Project mention: Show HN: I 3D scanned the tunnels inside the Maya Pyramid Temples at Copan | news.ycombinator.com | 2024-10-15
You should be able to do this with nerfstudio: https://github.com/nerfstudio-project/nerfstudio/ I've done it a few times, you can test 3d Gaussian Splatting also instead.

Project mention: We are shutting down the Ondsel FreeCAD business | news.ycombinator.com | 2024-11-18
OpenSCAD is my go-to. It's self-contained and AI coding tools know the syntax well enough to help you move fast. Unfortunately I keep hitting a complexity ceiling.
If it doesn't like how I'm describing something, it crashes. I have to load an older version of my .scad and try a new approach. This usually happens 70% of the way into a complex project, which is quite discouraging.
The Python ecosystem has CadQuery[0] and a few other tools built around the Open Cascade kernel[1] which is quite good in my limited experience. CadQuery is positioned as an OpenSCAD alternative [2], and I really want it to be. Unfortunately the user experience isn't there yet.
Making an object with CadQuery is writing a Python program. Which means you need a Python environment and dev setup. CQ-editor [3] is nice, but needs a Python environment first. I think CadQuery would be much more viable OpenSCAD alternative if it was packaged into a standalone CQ-editor application and published via homebrew, etc.
I'm also interest in Zoo [4](fka KittyCAD). They're trying to create a modelling tool that combines model-by-code and model-by-mouse. With some AI layered on top. They have an interesting architecture where they stream geometry to your local device from the cloud. Should be great for performance, but ties you to the cloud.

MeshAnything
[ICLR 2025] From anything to mesh like human artists. Official impl. of "MeshAnything: Artist-Created Mesh Generation with Autoregressive Transformers"
-
I mostly use tools like this for data exploration in Jupyter notebooks and PyVista was fine when I tried it out last year. However, I found I could get results much faster with Vedo[0].
No hate though, I'm so glad there are options in this space!

https://github.com/3DTopia/OpenLRM (They mention NeRF as inspiration but it seems original paper it was based on decided to use visual transformers. the opensource version seems to use meta's dino as one of key components)

K3D-jupyter
K3D lets you create 3D plots backed by WebGL with high-level API (surfaces, isosurfaces, voxels, mesh, cloud points, vtk objects, volume renderer, colormaps, etc). The primary aim of K3D-jupyter is to be easy for use as stand alone package like matplotlib, but also to allow interoperation with existing libraries as VTK.
