Horizon Engine – C++20 3D FPS Game Engine with ECS and Modern Renderer
Hi HN, I’m working on an experimental 3D FPS game engine in C++20, aiming to deeply understand engine internals from first principles rather than just using existing frameworks. Currently I'm strictly following LearnOpenGL docs. This project focuses on: Entity-Component-System (ECS) architecture for high performance. OpenGL 4.1 rendering with a PBR pipeline, material system, HDR, SSAO, and shadow mapping. Modular systems: input, physics (Jolt), audio (miniaudio), assets, hot reload. A sample FPS game & debug editor built into the repo. Repo:…
Horizon Engine – C++20 3D FPS Game Engine with ECS and Modern Renderer launched on January 10, 2026 with 5 votes, #3,400 of 14,584 launches that month and more than 75% of that year's launches.
What it does
C++20 3D FPS Game Engine with ECS architecture, OpenGL 4.1 renderer, and action-based input system - jackthepunished/horizon-engine
A modern C++20 game engine built for high-performance graphics and gameplay, featuring a Vulkan Deferred Renderer , Entity-Component-System architecture, and Jolt Physics. I'm building this engine to learn and experiment with modern rendering architecture (Vulkan, Render Graphs, GPU-driven rendering) and engine design patterns. Note : This project is currently in active development. The renderer has been recently migrated from OpenGL to Vulkan . ⟳ Vulkan Deferred Renderer : The rendering backend has been completely rewritten using Vulkan 1.3. It now features a state-of-the-art Deferred Rendering pipeline with G-Buffer, Cascaded Shadow Maps, andfrom github.com

I've been working on an MMORPG that is now in alpha as a solo developer. Here are the major open source technologies that I use: Blender - 3D modeling software for creating the overall environment and every game object. I've gotten a lot of CC and Public Domain assets from https://poly.pizza GLTF - I export assets from blender to the GLTF asset format JSON - I write a JSON config for every game object that describes things like its name, its interactions, its collisions, etc. Node.js exporter - I iterate over the environment and every asset to create a scene hierarchy. I use…
StratusGFX, my open-source real-time 3D rendering engine2023 · github.com · ▲483It'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.

I even wrote my own texture atlas packer, which is now used by Assassin's Creed, 2 scientific publications as well as a drone manufacturing company - each of these basically mentions the name of my game. There is even a claim that Unity patented some of the ECS ideas that originate from this project. See https://github.com/TeamHypersomnia/Hypersomnia#tech-highligh... for details. By the way the game is pretty darn good. 10 people connected yesterday to test a new map:…

Talanoa▲346Hi 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…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
