    Shaderc

    Shaderc

    A collection of tools, libraries, and tests for Vulkan shader

    Shaderc is a collection of tools and libraries for compiling shaders—small programs that run on GPUs—into SPIR-V, the intermediate representation used by the Vulkan graphics API. It provides both a command-line tool (glslc) and a C/C++ library (libshaderc) that wrap the functionality of glslang (the Khronos reference compiler for GLSL) and SPIRV-Tools to deliver a modern, scriptable, and efficient shader compilation workflow. The glslc compiler offers a GCC/Clang-like interface for building...

    Vercel Zero

    Vercel Zero

    The programming language for agents

    Zero is an experimental programming language from Vercel Labs designed with AI agents as first-class users. The project explores what a language, tooling system, and standard library might look like if agents need to read, debug, repair, and ship code reliably. It focuses on a small and regular language surface, structured diagnostics, predictable tooling, and machine-readable outputs. Zero is still pre-1 and intentionally unstable, so its syntax and APIs are meant for exploration rather...

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

    PortableGL is a single-header, software-only implementation of a subset of OpenGL (specifically the GL 2.1 pipeline), designed to run entirely on the CPU. 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.
