If you have interesting crease patterns that would Other contributors include Sasaki Kosuke, Erik Demaine, and others.Ĭode available on Github. Originally built by Amanda Ghassaei as a final project for Geometric Folding Algorithms. This app also uses the methods described in Simple Simulation of Curved Folds Based on Ruling-aware Triangulation to import curved crease patterns and pre-process them in a way that realistically simulates the bending between the creases. Freeform Variations of Origami by Tomohiro Tachi.Origami Folding: A Structural Engineering Approach by Mark Schenk and Simon D.The solver extends work from the following sources: Fast, Interactive Origami Simulation using GPU Computation by Amanda Ghassaei, Erik Demaine, and Neil Gershenfeld (7OSME)Īll simulation methods were written from scratch and are executed in parallel in several GPU fragment shaders for fast performance.It does this by iteratively solving for small displacements in the geometry of an initially flat sheet due to forces This simulation attempts to fold every crease simultaneously.

It may look a little differentįrom what you typically think of as 'origami' - rather than folding paper in a set of sequential steps,

This app allows you to simulate how any origami crease pattern will fold.
