Circle Packing: The efficient arrangement of circles on a square where each circle represents a flap; this ensures paper is not wasted, preventing complex models from becoming too bulky.

The Base: Fold the paper according to the mathematical crease pattern to reach a "base"—a raw shape with the correct number and length of parts. Robert Lang’s book

3. Lang’s Tree Method

• Purpose: Convert a stick-figure “tree” (a rooted, weighted graph representing limb lengths and flap widths) into a crease pattern that allocates dedicated paper regions to each appendage.
• Steps:

  3. The Unwritten Secret: Hierarchical Design

  Lang provides a step-by-step algorithm (the "Lang Universal Molecule") to divide a piece of paper into polygons that collapse into such a base. This was the algorithm that allowed him to do something previously thought impossible: fold a paper with hundreds of legs. this ensures paper is not wasted

  A technical approach using a grid of squares and diagonals, popular for complex insects and human figures. It’s the "digital" language of origami. Why You Should Read It
