AI Analysis

●●SolidWizardryNiche Gem

100k LOC custom OpenGL engine built by a teenager before the AI coding era.

Strengths

•Custom renderer with SSR, SSAO, and skinned mesh animation built manually.
•Entity component system and Python scripting integration designed from scratch.

Weaknesses

•Eight-year-old codebase with no recent commits, serving as a portfolio archive.
•Windows and Linux support only, missing macOS builds for modern developers.

Post Description

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.
