kaigen3d engine demo: cross-platform AI-first 3D engine hits 330+ FPS on 6-year-old laptop GPU
gdechichi · x · 2026-09-26
Developer gdechichi unveiled the first demo of kaigen3d, a 3D engine designed to work well with AI. Unlike Three.js, its output runs on Windows, Mac, iPhone, Android, and the web (VR coming soon), and the Minecraft Test demo hits 330+ FPS on a six-year-old laptop GPU.
Design principles shared in the thread:
- The engine runtime is code-first, not bundled with an editor, and users control the frame loop — decisions that turned out ideal for AI collaboration
- The author is a veteran of shipping games with Unity and Unreal and built kaigen3d to fix their known pains, not as 'better Three.js'
- Web is first-class because shareable playable links are great for distribution; Three.js proves the value but can't ship anywhere else
Demo and code linked in the original thread.
