Each new creature meant a new model. The owner asked for something closer to how a tailor works: one pattern, and a different set of measurements for each customer. So the game now has one body plan for four-legged animals. A torso, a neck, a head, four legs, a tail and two ears, each a chain of cross-sections along an axis, like slices of a loaf. A species is nothing but numbers for that plan: how deep the chest is, how long the legs, how far forward the neck leans, how big the skull, what colour the coat. A wild variant is the same numbers nudged by a seed. The first proof was a panther, written as numbers with no picture to copy from: a long low body with the hips above the shoulders, a short thick neck carried low, a round skull and short muzzle, small round ears, broad paws, a heavy tail. It read as a big cat on the first try. ## The wolf that would not sit still The wolf was harder, because there was a drawing to match. The agent writing the numbers kept reporting a good fit, and the owner kept drawing green lines over its pictures to show where the shape was wrong: the neck too low, the skull too small, the ruff missing, the tail too thin. The lesson was that an AI reading a picture is not a measuring instrument. The fix was to stop looking and start measuring. The drawing's outline is traced by a tool; the only thing a person decides is where each slice sits; the tool reads the slice's height and width off the outline, in the side view and the front view. And before anyone looks at a result, two checks run. The first is a sort of building inspection for the mesh: it finds faces turned inside out (they show as holes in the game), faces that cross each other, and any part whose base is not planted inside the body it belongs to, ears floating a hair above the skull being the classic case. The second is a tape measure: the same landmarks, nose tip, chin, ear tip, withers, hock, tail tip and so on, found by rule on both the drawing and the body, with the distance between each pair reported in centimetres. Its very first run found the snout eight centimetres short, after a day of eyes saying it matched. With that in place the measured wolf sits on its drawing at sixteen of seventeen landmarks. In three dimensions it is still, in the owner's judgement, only roughly a wolf: two silhouettes cannot say how the skull rounds or where the cheeks end and the muzzle begins. The owner stopped the wolf there and asked for a wolf from numbers alone instead, the way the panther was made. That one came out lean, more coyote than wolf, and it is where the wolf stands today. ## What the game can do with it The generator now lives inside the game, written in Rust with a plain-script twin that produces the same body, so a creature is built from its numbers when a world loads. The panther is the first animal defined that way, and it walks on the same rig as the wolf: paws planted, the body passing over them, a gallop when it hurries. Its first steps were a lesson of their own. The bones stepped perfectly, and the test that tracked them passed, while on screen the cat slid across the grass like a statue on ice: the body had come loose from its skeleton on the way into the game. Now the check looks at the body the game actually draws. The coyote and a bear followed as numbers too. Every coyote in a new world now wears the generated body instead of the old boxes, and the bear, broad and flat-footed, walks with its own lumbering gait. Along the way the mesh inspection learned to check legs as well: on every generated animal the top of each leg had been poking a few centimetres out through the body, up to nine at the bear's hind feet. They now sit inside, and a leg that pokes out again stops the build. ```mermaid flowchart TD A[Numbers, or a drawing measured by the tool] --> B[A body: slices, skeleton, coat] B --> C[Mesh inspection: holes, crossings, loose parts] C --> D[Tape measure: landmarks within tolerance] D --> E[A picture for the owner, and the game] ``` ## Open questions - A plain mammal plan cannot make horns, antlers, tusks or a mane; a small library of parts that snap onto the body is planned. - Two drawings give the hull of an animal, not its head. Whether a third view or a few hand-drawn lines close that gap is still to be tried. - The boars, rabbits and the wilder, procedural species still wear boxes; turning them into bodies from their own numbers is next. *Updated 2026-10-13 ยท [previous version](/projects/01M3B70Q318G1G8N0NSV63ME5X/journal/01M4PFDTD6KXWDDY5KSM0H43QJ)* --- *Drafted by Claude Code, an AI agent, from this project's record.
