    PocketSVG

    PocketSVG

    Easily convert your SVG files into CGPaths, CAShapeLayers, etc.

    A simple toolkit for displaying and manipulating SVGs on iOS and macOS in a performant manner. The goal of this project is not to be a fully compliant SVG parser/renderer. But rather to use SVG as a format for serializing CG/UIPaths, meaning it only supports SVG features that can be represented by CG/UIPaths. Thoroughly documented.

    PortableGL

    PortableGL

    An implementation of OpenGL 3.x-ish in clean C

    ...This lightweight graphics library allows OpenGL-style rendering without GPU acceleration, making it ideal for educational use, debugging, embedded systems, and retro-style software rendering. Because it mirrors OpenGL syntax and design, it can act as a drop-in CPU renderer for testing or deploying 3D graphics on platforms without GPU support.

    Ink

    Ink

    React for interactive command-line apps

    ...Apart from being built for CLIs, one other key difference between the two is that with Ink, the rendering doesn’t result in a DOM but a string, which Ink writes to the output. Ink is a React renderer, so all features of React are supported. Dozens of projects currently use Ink. You can check it out live on https://ink-counter-demo.vadimdemedes.repl.run/

    A tiny immediate-mode UI library

    microui is a tiny immediate-mode user interface library designed for developers who want a minimal UI foundation without a heavy framework. It follows the immediate-mode pattern, where the interface is rebuilt each frame from application state instead of being stored as a large retained widget tree. The project is intentionally small and gives developers room to add their own controls, rendering backends, and interaction patterns. It is especially useful for tools, games, editors, embedded...

    ezEngine

    ezEngine

    An open source C++ game engine

    ...This makes it possible to only include those features that you need, or to replace systems with a custom solution that works better for your requirements. Similarly, the EZ code base can be built in multiple tiers, where you either get the entire feature set, with a fully functional editor, asset management and renderer, or you can strip it down to just the base libraries and core engine functionality. This can be extremely useful if you need to build a lot of custom technology, but require a high-performance, reliable foundation. EZ has a strong emphasis on providing robust, easy to use and well-tested base functionality. It is successfully being used in such a capacity in commercial products.

    React Three Fiber

    React Three Fiber

    A React renderer for Three.js

    Build your scene declaratively with re-usable, self-contained components that react to state, are readily interactive, and can tap into React's ecosystem. There is no hard dependency on a particular three.js version, it does not wrap or duplicate a single three.js class. It merely expresses three.js in JSX, <mesh /> becomes new THREE.Mesh(), and that happens dynamically. There is no additional overhead. Components participate in a unified render loop outside of React. It outperforms three.js...
