  3. LLGL

    Low Level Graphics Library (LLGL) is a thin abstraction layer for the modern graphics APIs OpenGL, Direct3D, Vulkan, and Metal

  4. SoftGLRender

    Tiny C++ Software Renderer / Rasterizer, and implements OpenGL and Vulkan renderers for comparison

  5. MethaneKit

    🎲 Modern 3D graphics made simple with C++20 cross-platform framework and rendering abstraction API on top of DirectX 12, Vulkan & Metal

  10. tyra

    Game engine for PlayStation 2â„¢

  11. canvas_ity

    A tiny, single-header <canvas>-like 2D rasterizer for C++

    Project mention: Canvas_ity: A tiny, single-header <canvas>-like 2D rasterizer for C++ | news.ycombinator.com | 2026-02-21

    Author here. I have a JavaScript port of my automated test suite (https://github.com/a-e-k/canvas_ity/blob/main/test/test.html) that I used to compare my library against browser implementations. I was surprised by all of the browser quirks that I found!

    But compiling to WASM and running side-by-side on that page is definitely something that I've thought about to make the comparison easier. (For now, I just have my test suite write out PNGs and compare them in an image viewer split-screen with the browser.)

  12. luz

    C++ Path Tracer from scratch with zero third-party libraries. (by themartiano)

    Project mention: Show HN: I wrote a C++ ray tracer from scratch without AI | news.ycombinator.com | 2026-06-15

  13. RasterIX

    OpenGL 1.x implementation for FPGAs

  14. CroissantVulkanRenderer

    Real-Time Vulkan Renderer with features like PBR, IBL, and more.

  15. Voxel-Render

    C++ voxel rendering engine

  16. HORenderer3

    A C++ software renderer implementing the OpenGL Core pipeline, with a spec-based API, GPU state machine, and programmable shader model.

    Project mention: Show HN: HORenderer3: A C++ software renderer implementing OpenGL 3.3 pipeline | news.ycombinator.com | 2026-01-17

  17. EffinDOM

    EffinDOM is what happens when you stop pretending the DOM is fine and build a real runtime instead.

    Project mention: While Microsoft Is Busy Learning Rust, I'm Rebuilding .NET for WASI | dev.to | 2026-09-23

    While working on EffinDOM and Fui, Kotlin/Wasm brought that old question back into focus. It has a path to WebAssembly that doesn't have to take the JVM along for the ride. I wanted to see what a similarly deliberate path for C# could look like.

  18. Hemlock-Renderer-Opengl-3D-PBR-Renderer

    Opengl based 3D real time PBR render engine.

  19. Four

    A 4d rendering library written in C++ with Modern OpenGL (by ndm767)

  20. SaaSHub

    SaaSHub - Software Alternatives and Reviews. SaaSHub helps you find the best software and product alternatives
