Show HN: Hedra – an open-world 3D game I wrote from scratch before LLMs (opens in new tab)

With the current inflow of LLM aided software, I thought I would share a cool "hand-coded" project from the previous era (I wrote this in highschool so roughly ~8 years ago).

Hedra is an open world 3d game written from scratch using only OpenGL and C#. It has quite a few cool features like infinite generation, skinned animated mesh rendering, post processing effects, etc. Originally the physics engine was also written from scratch but i swapped for the more reliable bulletphysics.
