Model the Adizero Adios Pro Evo 3 in Blender and build its product page

the prompt

Model the adidas Adizero Adios Pro Evo 3 in Blender as photorealistically as you can, then build its product page with that model live and interactive on the page. Context you should know: this is going into a video watched by a large audience, your page is shown on camera against two other frontier models doing the same task, and your work will be credited to you by name. Every model gets this identical prompt and the identical reference photographs. What is being judged first is how close your shoe looks to the real one. **Reference photography is in `./refs/`** — official adidas studio shots of colourway Cloud White / Core Black / Solar Turbo, style code KH7678. `evo3-3.jpg` and `evo3-8.jpg` are profile views and are your primary geometry reference. `evo3-2.jpg` is the sole plan, `evo3-1.jpg` top-down, `evo3-5.jpg` rear three-quarter. `evo3-13.jpg`, `-6`, `-7`, `-10` are macros of the midsole step, the upper texture, the collar and the lacing. Look at them before you model anything, and keep checking back. ## Use Blender, headlessly Blender 5.1.2 is at `/opt/homebrew/bin/blender`. Drive it with `blender --background --python <your_script.py>`. Build the model in Python so you can iterate: re-run, render, look at the render, fix, re-run. Do not hand-place vertices you cannot regenerate. Render turntable and detail stills to `./renders/` with Cycles and actually look at them. A model you never rendered is a model you never checked. Export `./shoe.glb` (glTF 2.0, Draco compression on) for the web page. Keep it under 8 MB. ## The construction, which is published and specific Get these right. They are the difference between this shoe and a generic running shoe. 1. **There is no plate.** It uses **ENERGYRIM**: a carbon perimeter rim in a **U shape, open at the front**, leaving bare foam underfoot. It is **asymmetric** — continuous along the lateral side, but on the medial side it stops in the heel and reappears in the forefoot. A full-length carbon plate is wrong and will be visible in the cutaway. 2. **Midsole: Lightstrike Pro Evo.** Off-white, matte, visibly foam rather than plastic — sculpted, with open cell structure at the cut edges. It is **two-tier**: an upper body and a stepped lower keel, with a **thin black pinstripe tracing the bond line** along the sidewall. Stack is 39 mm heel; adidas markets 36 mm forefoot but independent measurement puts it nearer 33 — model nearer 39/33 and the rocker will read correctly. Aggressive forefoot rocker, toe tip lifting ~6.5 cm off the ground. 3. **Upper: ultralight ripstop**, derived from kitesurf sail material. Translucent white with a fine square grid. It is **non-stretch**, so it drapes and wrinkles rather than shrink-wrapping the foot — model the wrinkles, they are the tell. 4. **Three Stripes as a halftone dot matrix**, not solid black. Large dots thinning toward the edges. 5. **Outsole: Continental rubber**, a single teardrop pad over the forefoot only with about six curved sipes, plus a small translucent heel window. Everything else is bare foam. The rubber is charcoal with a violet cast, not black. 6. **No heel counter, no insole, no gusset on the tongue.** The tongue is thin and unpadded with a second lace loop low on the side. Laces are flat, white and short, running through translucent film loops. 7. **Stamped text** in small condensed caps: `LIGHTSTRIKE PRO EVO` on the foam, `ADIZERO ADIOS PRO EVO 3` on the upper. Sampled colours from the official photography: whites `#EAEEEF`, blacks `#2F3032`–`#3A3B3F`, Continental rubber `#48474D`, Solar Turbo accent `#FE7875` bright / `#D34144` in shadow. ## The page 8. **A single self-contained `index.html`** that loads `shoe.glb` and puts it on the page live — orbitable, lit properly, with real materials. three.js via CDN is fine. No build step, no server, no API keys. 9. **Scroll drives a sequence**: the shoe rotates, the upper fades to expose the ENERGYRIM, the midsole separates from the outsole, annotations appear anchored to each part. Scrubbing backward runs cleanly in reverse. 10. **A complete product page**, not just a viewer: hero, the scroll sequence, a spec table (weight 97 g at UK 8.5, stack 39/36 mm, 3 mm drop, $500), a section on the record run, a materials section, and a purchase call to action. Write copy that sounds like adidas, not placeholder text. 11. **Sixty frames per second** while scrolling and orbiting. Profile it and fix it. 12. **Responsive** down to a phone. ## QA 13. Put your render side by side with `refs/evo3-3.jpg` and compare silhouette, midsole step, stripe placement and rocker angle. Fix what is off. Then load the page, scroll it top to bottom and back several times, orbit the shoe, check the frame rate and the console. Write `BUILD_NOTES.md` covering what you got close on and what you could not match.
