Pascal Editor is a free, open-source 3D building tool using React Three Fiber and WebGPU. It structures scenes with nodes (walls, slabs, zones) in a flat store, managed by Zustand for undo/redo and IndexedDB saves. Systems efficiently update dirty nodes' geometry in the render loop via a scene registry, avoiding React re-renders for smooth performance. Run `bun dev` from root to start. You benefit by quickly building interactive 3D models like buildings or rooms in-browser with tools for drawing, placing items, and real-time edits—faster and more scalable than raw Three.js.
