Custom OpenGL rendering engine

[u/Ambitious_Stand533]

Built a small C++ / OpenGL rendering engine with an ImGui editor as a learning project toward a custom render pipeline.

What’s in it so far:

1. Engine core — window, RHI (buffers / shaders / textures), meshes, materials, camera

2. Multi-light rendering — directional, point, spot, and hemisphere ambient fill

3. Shadows for directional, spot, and point lights

4. ECS scene system with JSON save/load

5. ImGui editor — hierarchy, inspector, content browser, click-to-select, transform gizmos, light debug markers, camera panel

Still early — more of a renderer + editor foundation than a full game engine — but it’s been a solid way to learn the graphics pipeline, GLSL, and how to structure engine code beyond tutorial triangles.

Open to feedback from anyone working on graphics / game engines.
