sdf

That feature requires getting pyopenvdb installed, which can be a headache, and I never really updated the README with examples, but it does work. There is one example script: https://github.com/fogleman/sdf/blob/main/examples/mesh.py You basically just say: f = Mesh.from_file(path).sdf(voxel_size=0.25, half_width=1) Then you can operate on `f`.

It is kinda neat, but OpenSCAD's limitations are the main thing that motivated me to write this Python library to generate 3D meshes used signed distance functions: https://github.com/fogleman/sdf One big plus to doing it this way is that it's "just" Python and you can use arbitrary logic to help construct your model. You can even load an existing 3D mesh and operate on it as an SDF. Great for hollowing, chopping, eroding/dilating, etc. existing models. I should probably do more with this project. I think there's a lot of interest in this space.

Mostly speed, I'm mostly doing large boolean unions of primitives or chain hulls and OpenSCAD chugs pretty good at large numbers of operations. Don't get me wrong, they're great tools for what they're good at. I need to do more research before I start a port, SDFs seem like the best option but I'm not 100% confident. I am considering using your SDF library though (github.com/fogleman/sdf) but need do do some experimenting/benchmarking first.

This is a little hobby/side project i've been working on . Its tool for constructive solid geometry using python which runs in your browser (best viewed on desktop). The gist of it is it runs in your browser(pyodide) you write high level python which generates the corresponding glsl for your objects signed distance function which is then rendered using webgl (raymarching). The objects can then be converted to an STL (marching cubes) and downloaded while SDF's for csg has been done before , https://github.com/fogleman/sdf , it requires you to generate the mesh and view it in a seperate viewer . Here instead i render the sdf with a fragment shader onto a canvas. Python is neat, a lot of people know it or can pick it up fast and i thought its the perfect language for small time 3d printing hobbyist or designers to quickly conjure something u
