  • Minecraft Clone (Development)

    A Minecraft clone written in C++11 using OpenGL.

  • 3D Graphics Library (Development)

    3D graphics library with support for software rendering using a fast custom engine and hardware rendering using OpenGL. Supports output to window, disk (using FFmpeg), or terminal (using AAlib or caca). Supports render-to-texture.

  • SSA-based Optimizing Compiler Back-end (Development)

    SSA-based optimizing compiler back-end. Currently targets x86 32 and 64-bit Linux. Supported optimizations include constant propagation, dead code elimination, register allocation, and control-flow simplification.
