Rust/WASM lighting data toolkit – parses legacy formats, generates SVGs

In plain words

This toolkit parses lighting industry data formats, handling both legacy standards from the 1990s (EULUMDAT, IES) and newer spectral data formats (TM-33, ATLA-S001). Built in Rust with WebAssembly support, it generates SVG visualizations and includes a 3D viewer powered by Bevy. The core codebase compiles across multiple platforms including web, iOS, and Android through a unified architecture. It targets lighting professionals and developers working with photometric data who need compatibility with older formats alongside support for modern spectral wavelength analysis.

In the maker’s words, at launch

Hi HN, I'm Holger, a developer who worked in the lighting industry. I built this to scratch my own itch and put it on crates.io and PyPI where nothing like it existed. The old file formats (EULUMDAT from 1990, IES from 1991) still work fine for basic photometry. But the industry is moving toward spectral data – full…

  Browser-based light pollution simulator using real photometric dataMay 2026 · iesna.eu · ▲44

  Hi HN — author here. iesna.eu is a browser-based ecosystem for working with photometric data: parsing standard luminaire files (LDT/EULUMDAT, IES LM-63, Oxytech, ATLA-S001), running design calculations against EN 13201 / ANSI/IES RP-8 / CJJ 45 / IES-IDA MLO, and (the part I most want to show off here) rendering real urban scenes in Bevy with the photometric data driving actual streetlight behavior, including sky-glow contribution. The Skyglow Analysis demo loads a real LDT file into a Bevy scene (Khronos Bistro test asset). The luminaire's intensity distribution…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Community, All the HN belong to you. This is an archive of hacker news that fits in your browser. When I made HN Made of Primes I realized I could probably do this offline sqlite/wasm thing with the whole GBs of archive. The whole dataset. So I tried it, and this is it. Have Hacker News on your device. Go to this repo (https://github.com/DOSAYGO-STUDIO/HackerBook): you can download it. Big Query -> ETL -> npx serve docs - that's it. 20 years of HN arguments and beauty, can be yours forever. So they'll never die. Ever. It's the unkillable static archive of HN and it's…
