Pascal Launches an Open-Source 3D Building Editor With AI and Agent Support

Summary

Pascal is an open-source browser-based editor for creating and sharing 3D architectural projects and digital twins. Users can scan a space, convert it into a 3D scene, or sketch a new structure, then edit walls, furniture, layouts, and visual styles before presenting the result in a first-person walkthrough. The product advertises AI support through GPT-6 Astra, Fable 5.1, and Gemini 3.8, with usage consuming AI credits. Its AI workflow can turn sketches drawn directly on a model into solid geometry. Pascal also provides SDF/CSG-based shapes for parametric modeling, an asset library of ready-made 3D objects, and rendering tools for materials such as glass and procedural surfaces. The viewer, editor, and scene engine are published on npm, and the project is MIT-licensed so developers can embed or extend the components and import IFC models through its converter. An MCP server allows agents to inspect and reshape scenes, including rooms, objects, materials, and building systems. The platform targets homeowners, architects, contractors, property developers, game designers, production teams, developers, and companies working with digital twins.
