OpenGL rendering engine mainly to toy with real-time graphics programming.
It's architecture follows game engine patterns but it's not meant to be a game engine.
I'm developing in the following environment and won't consider backward compatibility or other OS.
- GL version: OpenGL 4.6 Core Profile
- Language: C++17
- OS: Windows 11
- IDE: Visual Studio 2022
- Clone this repo.
- Run
Setup.ps1to download media resources. (you need execution policy for PowerShell script) - Build all projects in
PathosEngine.sln. - Execute one of test projects.

Area light sources (sphere light and rect light).
Asynchronous Wavefront OBJ asset loading, local lights with omnidirectional shadow mapping, screen space light shaft, and screen space ambient occlusion.
Procedural geometries and textures, volumetric clouds, and post process bloom.
Procedural geometries and sky.
Asynchronous glTF asset loading, Cook-Torrance BRDF for local illumination, and basic sky IBL for global illumination.
Yet another Sponza scene.
- Rendering pipeline

- Bloom
- Tone mapping
- Anti-aliasing (FXAA, TAA)
- Super resolution (AMD FSR1)
- Depth of field
- Engine subsystems
- Render thread
- Asynchronous asset loaders (Wavefront OBJ, glTF)
- Scene capture (rendering from separate views other than the main view)
- Runtime shader recompilation
- Actor system (component-based development)
- Material shader assembly system (generate material shaders from templates so that they can run in frame rendering pipeline)
- RenderDoc integration
- Console variables and console window
