Browser-based WebGL terrain editor with authoring mode and camera

Hacker News

Hi HN, I’m building browser-based WebGL terrain editor powered by a custom Three.js engine. It’s a real-time 3D scene, not a static render. What’s new since the last iteration: Authoring mode UI integrated into the left navigation (clean tool separation, no ad-hoc overlays) Camera Mode vs Explore Mode (orbit/zoom author camera with a clear mode switch) Visual modes for authoring (production parity vs simplified white “workspace” mode) Live demo: https://playzafiro.com/isle-lab/ Short context: I’m doing this solo. The long-term goal is a lightweight world-building tool that can evolve into a broader editor/workflow. I’d love feedback on: - usability (does the navigation/tooling feel intuitive?) - performance on your machine - what feature would make this immediately useful for you (even as a prototype) Thanks!
