A toy rendering engine. Sandbox for my experiments in computer graphics.

• Windows 7 and older

• OpenGL 4.5

• Stable cascaded shadow maps
• Physically based materials with Cook-Torrance BRDF (Unreal Engine approach mostly)
• Image based enviroment lightning (Unreal split-sum approximation)
• FXAA
• HDR with global filmic (approximated) tonemapping

• Asynchronous resource loading
• Simple scene serialization
• Simple editor
• Runtime code hot-reloading [1]
• Manually implemented win32 platform layer (definetly has tons of bugs)

Just find and run vcvars.bat for x64 in your command promt and then go to project directory and run build.bat
