The owner spotted something odd about those stripes: up close, their edges came out as a checkerboard of triangles. The question was whether that was a mistake. It wasn't a mistake, exactly. The bodies are made of flat faces, and each face had one colour. A stripe is narrower than the faces it crosses, so its edges cut faces in half, and each half picked a side: stripe or coat. The first fix cut extra faces along every stripe's edge, so each band became whole faces with straight edges. The owner turned it down: painting a pattern should not change the shape it's painted on. What they asked for instead was a system that paints patterns on its own. That system is a shader: a small program on the graphics card that decides the colour of every point as it's drawn. Every point on the body carries where it sits on the animal standing still, so a stripe painted there stays put on the body as the animal walks, and its edges stay sharp however close the camera gets. No faces are added. The first try painted stripes and spots on the flanks only. The owner liked it and asked for more. Some animals carry marks only in places, like a back, a neck or the legs, while others are marked all over, like a zebra or a leopard. They also noticed that spots at the edge of the marked area were sliced in half, which no real animal has. So now every point also knows which part of the body it is on: back, belly, neck, head, legs or tail, and how far along that part. And a spot is kept or dropped whole, by where its middle lands. One more round came from a screenshot. The giraffe coat leaves the lower legs plain, and "plain" let the animal's old colour show through, so a green coyote wore a giraffe's coat over green shins. Plain now means the coat's own light colour. Each made-up species now rolls its coat from its markings: a subtle one (plain, a spine stripe with socks, or tail rings with a mask), one in places (dapples along the back, pinto patches), or one all over (zebra, leopard, giraffe, tiger). The family sets the odds: grazers lean to dapples and giraffe nets, coyotes to stripes and rosettes, boars to bands and patches, rabbits to patches and dapples. Each species also gets its own pattern size and mark colours tinted towards its coat. Hooves stay dark, and predators' eyes still glow at night. ## Open questions - Should some families never roll certain coats? A spotted rabbit is possible today. - More motifs could join: fine speckle, a lighter belly, a pale rump patch. --- *Drafted by Claude Opus 5.5 (FARCAMP MODELS), an AI agent, from this project's record.
