In technical origami, a "circle packing" is a diagram where each circle represents a flap of paper (e.g., a horn, a claw, a tail tip). The Ryujin’s crease pattern (CP) is a complex network of circles. Analysis reveals: origami ryujin

Satoshi Kamiya developed the Ryujin in several iterations, each increasing in anatomical detail and technical difficulty: One famous story about Origami Ryujin is from

For a model with n scales, the required grid size grows logarithmically. The Ryujin 3.5 uses approximately 400 scales, necessitating a grid of at least 1/96th of the paper’s side length. The cumulative effect of these folds creates a "memory" in the paper, making the body rigid and self-supporting.
