BSPRenderer

This is a Half-Life 1 BSP loader and renderer written in C++ and OpenGL 3.3 Core.

Build requirements

  • OpenGL mathematics library (GLM)
  • SDL2 library

Note: code is designed to be portable but was only tested on Windows with Visual Studio 2017. Some patches may be required.

Lighting

The renderer suppports both GoldSrc lightmaps (in the .bsp file) and custom ones generated using rad utility.

Credits

A lot of rendering code is based on Xash3D so thanks to everyone who worked on it. Also thanks to id Software for open-sourcing Quake engine code which helped massively.
