Origami Crane — Folding Step by Step From a Flat Sheet
A single deformable paper mesh morphs continuously between a flat square sheet and a fully folded crane shape using a procedural formula rather than discrete geometry swaps. The formula narrows the wings, lifts a central ridge, and stretches the head and tail as a "fold amount" parameter increases, mimicking the progressive creasing of real origami.
- One 34×46 segment plane mesh reshaped per-vertex by a fold formula, no mesh swapping
- 9-stage fold sequence cycling from flat sheet to complete crane and back
- Vertex normals recomputed each frame for correct flat-shaded lighting
- Manual step scrubber lets you freeze and inspect any point in the fold sequence
