Top 23 Engine Open-Source Projects

  • tinyrenderer

    A brief computer graphics / rendering course

    Project mention: I have a few months to prepare for an interview. Is there a project that would get me at least part of the way there for the interview? | reddit.com/r/GraphicsProgramming | 2023-01-23

    In terms of a project which would be worthwhile, I think building a software rasterizer from scratch is a useful first step. TinyRenderer is a great place to start. Looking at the high level overview of many graphics subjects, ScratchAPixel is a valuable resource. Theres also just great information in some of the rote graphics programming textbooks (Michael Abrash's Black Book fully available online from Jason Gregory, and this book is really interesting). The "RayTracer in a weekend" series is also (seemingly) very illuminating (no pun intended).

  • bgfx

    Cross-platform, graphics API agnostic, "Bring Your Own Engine/Framework" style rendering library.

    Project mention: Cross platform low level graphics API suitable for game development? | reddit.com/r/gamedev | 2023-01-27

    Take a look at BGFX, sounds like its what you want. Its a cross platform graphics API that is low level like metal or opengl, however it treats opengl, metal, vulkan, etc as backends that u can compile to so you can write your code once and then compile to macos using metal as the backend, compile to web using webgl as the backend, compile for windows using directx as the backend etc etc. Its written in C++ but it has officially supported C bindings so you can use it with C no problem.

  • Sonar

  • OpenRA

    Project mention: I'm new to RTS games. What should I start out with? | reddit.com/r/RealTimeStrategy | 2023-01-31
  • openage

    Free (as in freedom) open source clone of the Age of Empires II engine :rocket:

    Project mention: AOE2 House made using Blender | reddit.com/r/aoe2 | 2022-12-17

    This looks incredible! It would look very good in OpenAge, a free and opensource re-implementation of AoE 2

  • flowy

    The minimal javascript library to create flowcharts ✨

    Project mention: Flowy: A JavaScript library to create pretty flowcharts with ease | news.ycombinator.com | 2022-12-04
  • unocss

    The instant on-demand atomic CSS engine.

    Project mention: Integrating UnoCSS with Yew | dev.to | 2023-01-22

    Even using Rust, though, I didn't want to give up my Atomic CSS classes. I'm accustomed to using Tailwind CSS with frameworks like Next and Astro, but recently I've replaced it with UnoCSS. It has a preset for Tailwind, but it's significantly faster.

  • flex-layout

    Project mention: What features would you like to see that are not available in leading game engines | reddit.com/r/gamedev | 2022-07-27

  • sciter-sdk

    Sciter is an embeddable HTML/CSS/scripting engine

    Project mention: RustDesk – The open source TeamViewer alternative | news.ycombinator.com | 2022-07-26

    I'm a bit curious here.

    I see that RustDesk is licensed AGPL 3.0. At the same time the GUI component (Sciter - https://www.sciter.com) is proprietary software with it's own non-compatible license (https://github.com/c-smile/sciter-sdk/blob/524a90ef7eab16575...).

    Was the intention to use something like LGPL to stand on the shoulders of the external libraries or was the choice of AGPL just a hopeful goal with licensing issues to be resolved in the future?

  • json-rules-engine

    A rules engine expressed in JSON

    Project mention: How should I test this function? Should I test all possibilities? Like hasDescription = true and hasExperience = true should return true. hasDescription = true and hasSkill = true should return false | reddit.com/r/webdev | 2022-09-20

    If you find yourself needing to do alot of these profile matching functions I would recomend building either a mini-rules interpreter or using something like this https://github.com/CacheControl/json-rules-engine to do the matching for you.
