An iOS app written in Swift that enables users to design 3D paper pop-ups with guided geometry constraints and 3D simulation preview.

The Vision

Crafting 3D paper pop-ups can yield complex, expressive geometries, and can help develop spatial reasoning skills. This tool assists users in designing three-dimensional paper pop-ups through an innovative digital interface.

How It Works

The tool enables designers to draw lines while receiving guidance for creating geometrically sound pop-ups. Real-time 3D simulation lets you preview your creation before physical fabrication.

Development

This was a collaborative class project from CS189 F14 (Computational Fabrication) with Marissa Allen and Nook Harqual.

Features

  • Sketch-based interface for intuitive design
  • Guided geometry constraints to ensure valid pop-up structures
  • Real-time 3D simulation preview
  • Export for laser cutting and physical fabrication

User Testing

We conducted user testing with 23 undergraduate participants to validate the interface design and usability.
