Asdf Overlay – High performance in-game overlay library for Windows▲77
I am making a open source overlay library. Game overlay is for rendering contents on top of game screen. Representative examples are Discord and Steam in-game overlay. They are complicated because it has to hook rendering part of a game. Asdf overlay provides easy to use interfaces for rendering on top of game screen. I recognize game performance degradation due to overlay rendering, so GPU shared texture was used to avoid CPU framebuffer copy. Asdf Overlay is capable of rendering full screen overlay without noticeable performance loss.

A PSX/DOS style 3D game written in Rust with a custom software renderer▲57
So, after years of abandoning Rust after the hello world stage, I finally decided to do something substantial. It started with simple line rendering, but I liked how it was progressing so I figured I could make a reasonably complete PSX style renderer and a game with it. My only dependency is SDL2; I treat it as my "platform", so it handles windowing, input and audio. This means my Cargo.toml is as simple as: [dependencies.sdl2] version = "0.35" default-features = false features = ["mixer"] this pulls around 6-7 other dependencies. I am doing actual true color 3D rendering (with Z buffer,…

Horizon – GPU-accelerated infinite-canvas terminal in Rust▲84
Tabs, splits, and tmux work fine until you have several projects open with logs, tests, and long-running shells. I kept rebuilding context instead of resuming work. Horizon puts shells on an infinite canvas. You can arrange them into workspaces and reopen later with layout, scrollback, and history intact. Built in 3 days with Claude/Codex, dogfooding the workflow as I went. Feedback and contributions welcome.

Procedurally generated 3DGS splats powered by Spark▲11
Hello HN! I'm the author of this toy project that combines the idea of live-edit Shadertoy scenes with the popular gaussian splatting, aka 3DGS. You can write a GLSL function that defines the splats and see it rendered in real-time. Your GLSL code isn't stored anywhere, but you can share it via URL. P.S. I'm not a Spark developer. I'm just using their rendering engine.
