在 Web VR 中模擬任何摺紙摺痕圖案如何以 3D 形式折疊。
In Web VR simulate how any origami crease pattern will fold in 3D.

This app allows you to simulate how any origami crease pattern will fold in 3D. It may look a little different from what you typically think of as "origami" - rather than folding paper in a set of sequential steps, this simulation attempts to fold every crease simultaneously. It does this by iteratively solving for small displacements in the geometry of an initially flat sheet due to forces exerted by creases. This solver extends work from the papers “Origami Folding: A Structural Engineering Approach” by Mark Schenk and Simon D. Guest and “Freeform Variations of Origami” by Tomohiro Tachi. All simulation methods were written from scratch and are executed in parallel in several GPU fragment shaders for fast performance. The app also supports an immersive VR mode using Web VR on the Vive and Oculus, where you can interact with the folding origami directly and visualize its internal strain.

此應用程式可讓您模擬任何摺紙摺痕圖案如何以 3D 形式折疊。它可能看起來與您通常認為的“摺紙”有點不同 - 該模擬不是通過一系列連續步驟折疊紙張，而是嘗試同時折疊每個摺痕。它透過迭代求解初始平板的幾何形狀中由於摺痕施加的力而產生的小位移來實現這一點。該求解器擴展了 Mark Schenk 和 Simon D. Guest 的論文“Origami Folding：A Structural Engineering Approach”和Tomohiro Tachi 的“Freeform Variations of Origami”的工作。所有模擬方法都是從頭開始編寫的，並在多個 GPU 片段著色器中並行執行，以實現快速效能。該應用程式還支援在 Vive 和 Oculus 上使用 Web VR 的沉浸式 VR 模式，您可以直接與折疊摺紙互動並視覺化其內部張力。如需了解更多信息，請訪問http://www.amandaghassaei.com/projects/origami Simulator/
