[Other] Show HN: a Rust ray tracer that runs on any GPU – even in the browser I’ve been experimenting with Rust lately and wanted a project that would help me explore some of its lower-level and performance-oriented features. Inspired by Sebastian Lague’s videos, I decided to implement my own ray tracer from scratch.<p>The initial goal was just to render a simple 3D scene in the browser at a reasonable frame rate. It evolved into a small renderer that can: • Run locally or on the web using wgpu and WebAssembly • Perform mesh rendering with a Bounding Volume Hierarchy (BVH) for acceleration • Simulate both direct and indirect illumination for photorealistic results • Be deployed easily as a free web demo using GitHub Pages<p>The project is far from perfect, but it’s been a fun way to dig deeper into graphics programming and learn more about Rust’s ecosystem. I’m also planning to experiment with Rust for some ML projects next.<p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;tchauffi&#x2F;rust-rasterizer" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;tchauffi&#x2F;rust-rasterizer</a> Web demo (desktop browsers): <a href="https:&#x2F;&#x2F;tchauffi.github.io&#x2F;rust-rasterizer&#x2F;" rel="nofollow">https:&#x2F;&#x2F;tchauffi.github.io&#x2F;rust-rasterizer&#x2F;</a><p>Would love feedback from anyone who’s built similar projects or has experience with wgpu or ray tracing in Rust.

[CLI Tool] Show HN: Serie – A rich Git commit graph in your terminal Serie is a TUI application that uses the terminal emulators&#x27; image display protocol to render commit graphs like git log --graph --all.<p>This is not a full-featured git client, nor are there any plans to add such functionality, so it is not a replacement for tig, lazygit, gitui, etc.<p>The only purpose of this tool is to provide a pretty git log --graph and make commit information easily accessible.<p>While some users prefer to use Git via CLI, they often rely on a GUI or feature-rich TUI to view commit logs. Others may find git log --graph sufficient.<p>Personally, I found the output from git log --graph difficult to read, even with additional options. Learning complex tools just to view logs seemed cumbersome.<p>Limitations:<p>- Sixel is not supported. Only terminals that support the iTerm and kitty image protocols are supported.<p>- Terminal multiplexers are not supported.<p>- Windows is not supported.<p><a href="https:&#x2F;&#x2F;github.com&#x2F;lusingander&#x2F;serie" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;lusingander&#x2F;serie</a>

[Other] Show HN: Ambient light sensor control of keyboard and screen brightness in Linux I have always wanted cool features in Linux because I use it day to day as my OS. I have always wanted to implement this feature and do it properly: one that automatically adjusts keyboard and LCD backlights using data from the Ambient Light Sensor.<p>I enjoy low-level programming a lot. I delved into writing this program in C. It came out well and worked seamlessly on my device. Currently, it only works for keyboard lights. I designed it in a way that the support for LCD will come in seamlessly in the future.<p>But, in the real world, people have different kinds of devices. And I made sure to follow the iio implementation on the kernel through sysfs. I would like feedback. :)
