sprite · quadruped body plan

Quad Lab

Four-legged critters in pixels — a third body plan beside the humanoid and the radial echinoderm. Quadrupeds read in profile and need a real gait, so each leg is a tiny 2-bone IK chain animated by a diagonal-pair trot. Boar, hound, bear, robot are just points in the gene space; chassis turns flesh to steel.

Genome

Same kernel discipline

Pure seed-deterministic generator (buildQuadGenome / quadFrame) + animator (QuadCritter, gait = a closed-form f(t), reproducible from seed + #steps), node-tested. Portable still: GET /sprite/api/quad.svg?seed=&family=&body=&leg=&…. flip mirrors the profile; presets are just gene points.
