An Open Sourced Full 3D Building Editor<\/p>\n

Someone just open sourced a full 3D building editor that runs entirely in your browser.<\/p>\n

No AutoCAD. No Revit. No $5,000\/year licenses.<\/p>\n

It’s called Pascal Editor.<\/p>\n

Built with React Three Fiber and WebGPU — meaning it renders directly on your GPU at near-native speed.<\/p>\n

Here’s what’s inside this thing:<\/p>\n

A full building\/level\/wall\/zone hierarchy you can edit in real time
\nAn ECS-style architecture where every object updates through GPU-powered systems
\nZustand state management with full undo\/redo built in
\nNext.js frontend so it deploys as a web app, not a desktop install
\nDirty node tracking — only re-renders what changed, not the whole scene<\/p>\n

Here’s the wildest part:<\/p>\n

You can stack, explode, or solo individual building levels. Select a zone, drag a wall, reshape a slab — all in 3D, all in the browser.<\/p>\n

Architecture firms pay $50K+ per seat for BIM software that does this workflow.<\/p>\n

This is free.<\/p>\n

100% Open Source.<\/p>\n
