- Traditional rasterizer. It is intended to produce pixel-perfect identical frames to existing GL renderer as possible.
- Ray tracing. It implements real time path traced global illumination lighting with PBR materials. It will look noticeably different from original game.
- It is intended to be merged back into upstream/master when it gets mature and stable enough.
- If you feel adventurous, you can follow [build instructions](https://github.com/w23/xash3d-fwgs/wiki/How-to-build-a-64bit). Note that they might be slightly out of date, kek.
This project is 99% developed live on stream. I'm not a graphics programmer, and have no idea what I'm doing. I'm essentially learning Vulkan, game engine renderer development, linear algebra, and ray tracing techniques while getting hands dirty with this. This is all for your amusement.
Xash3D FWGS is a game engine, aimed to provide compatibility with Half-Life Engine and extend it, as well as to give game developers well known workflow.
Xash3D FWGS is a heavily modified fork of an original [Xash3D Engine](https://www.moddb.com/engines/xash3d-engine) by Unkle Mike.

If you like Xash3D FWGS, consider supporting individual engine maintainers. By supporting us, you help to continue developing this game engine further. The sponsorship links are available in [documentation](Documentation/donate.md).
* Multiple renderers support: OpenGL, GLESv1, GLESv2 and Software.
* Advanced virtual filesystem: `.pk3` and `.pk3dir` support, compatibility with GoldSrc FS module, fast case-insensitivity emulation for crossplatform.
* Mobility API: better game integration on mobile devices (vibration, touch controls)
* Different input methods: touch and gamepad in addition to mouse & keyboard.
0) Get Xash3D FWGS binaries: you can use [testing](https://github.com/FWGS/xash3d-fwgs/releases/tag/continuous) build or you can compile engine from source code.
If your CPU is NOT x86 compatible or you're running 64-bit version of the engine, you may want to compile [Half-Life SDK](https://github.com/FWGS/hlsdk-portable).
* Before sending an issue, check if someone already reported your issue. Make sure you're following "How To Ask Questions The Smart Way" guide by Eric Steven Raymond. Read more: http://www.catb.org/~esr/faqs/smart-questions.html
If your CPU is x86 compatible, we are building 32-bit code by default. This was done to maintain compatibility with Steam releases of Half-Life and based on it's engine games.
If your CPU is NOT x86 compatible or you decided build 64-bit version of engine, you may want to compile [Half-Life SDK](https://github.com/FWGS/hlsdk-portable).
* Download [SDL2](https://libsdl.org/download-2.0.php) development package for Visual Studio.
* Clone this repository: `git clone --recursive https://github.com/FWGS/xash3d-fwgs`.
* Make sure you have at least 12GB of free space to store all build-time dependencies: ~10GB for Visual Studio, 300 MB for Git, 100 MB for Python and other.
