24 alternatives to Open-Source Software for Designing 3D-Printable Luneburg Lenses for RF
Hi HN community, I’m excited to share my project, LuneForge, an open-source tool currently in development that aims to simplify the design of Luneburg lenses specifically for radio frequency (RF) applications. Luneburg lenses are unique gradient-index lenses that focus RF signals effectively, making them valuable in various RF and antenna systems aimed for military and automotive industry. Key Features: Customizable Designs: Easily adjust parameters to tailor lens designs to specific RF needs. User-Friendly Interface: Designed to be accessible for both RF professionals and hobbyists.…
LuneForge is an open-source tool for designing Luneburg lenses optimized for 3D printing and radio frequency applications. The software allows users to customize lens parameters for specific RF needs and features a… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Open-Source Software for Designing 3D-Printable Luneburg Lenses for RF launched in 2024; newer entries below may have overtaken it.

It's been closed source for a long time while I worked on it on and off as a hobby research project, but yesterday the repo was made public for the first time under the MPL 2.0 license. A feature reel showing its capabilities can be found here: https://ktstephano.github.io/rendering/stratusgfx/feature_re... A technical breakdown of a single frame can be found here: https://ktstephano.github.io/rendering/stratusgfx/frame_anal... It's still in a very beta state (bugs and instability expected), but I felt like it was a good time to make it…

Hi HN, I’m Joe. My friends Matthew, Jake and I are building Luminal (https://luminalai.com/), a GPU compiler for automatically generating fast GPU kernels for AI models. It uses search-based compilation to achieve high performance. We take high level model code, like you'd have in PyTorch, and generate very fast GPU code. We do that without using LLMs or AI - rather, we pose it as a search problem. Our compiler builds a search space, generates millions of possible kernels, and then searches through it to minimize runtime. You can try out a demo in `demos/matmul` on mac to…

LuaCAD models solids in Lua rather than the OpenSCAD language, with operator overloading for CSG (`a + b`, `a - b`, `a * b`). It ships with a CLI and a desktop app, including a preview area and a text editor. I've always been a big fan of OpenSCAD, but the SCAD language itself is unfortunately quite cobbled-together and is a very poorly designed programming language. LuaCAD takes all the good parts of OpenSCAD and combines them with one of the best scripting languages. It has now completely replaced OpenSCAD for me, and I think it provides a better experience than OpenSCAD for all use cases.…

This is significantly different in its feature set than the existing open source alternatives, I made this to be a more complete library, and well, as a portfolio artefact. Any comment is greatly appreciated. Thank you! Code: https://github.com/lusift/lusift

I've been going through Cem Yuksel's "Introduction to Computer Graphics" course and thought that writing a volume renderer would be a good way to test my knowledge. It is a common technique used to render 3D medical data. Works by ray marching a specific step size, reading a 3D texture (e.g. MRI data), and calculating opacity values. Code should be easy to get started with for anyone familiar with the JS ecosystem. Questions for the HN community: I spent 20-25% of the entire time just setting up the project and fighting issues with the JavaScript ecosystem. This experience has made me…
