Modern C++23 OpenGL4.6 engine that can be used as a starting point for more complex engines or games. It focuses on clarity and a small feature set while keeping modern practices.
- Instanced forward rendering, CPU batching by mesh/material with frustum culling.
- glTF/glb model loading with tinygltf.
- Frame UBO for per-frame camera and light data.
- Directional sun + ambient + optional point lights.
- Simple camera controller with mouse look and WASD movement.
- Wireframe toggle and fullscreen mode.
- Basic stats display with configurable update interval.
- Simple event system for input handling.
- Asset manager with caching for shaders, textures, materials and models using AssetHandle references.
- Simple config system with INI sections.
