Turn one image into a 3D simulator that takes itself apart. First, make one reference image with the image model selected for this run: "A robotic hammerhead shark as a precision machine, studio product shot on a near-white background with a soft floor shadow. White glossy shells with clearcoat, green only on tips, rims, edges and joint rings. Dense dark mechanism showing through cut-outs and clear glass: gears, pistons, hoses, small screws. Eyes as glossy black lenses with a thin green ring. Fins and membranes milky and frosted with thin veins. Front three-quarter view, the whole subject in frame." Then rebuild it in three.js on one web page, entirely in code: no 3D model files, and never use the picture as a texture. Read it and build your own. The look: white shells with clearcoat and an environment map; green as a sparse accent only (tips, rims, edge lines, a bezel, joint rings), never dots over a shell; dark mechanism in 2 levels, big parts (gears, rings, actuators) and about 260 small ones (pistons, hoses, screws, wiring), with windows cut into the shells so the dark mass shows; eyes as glossy black lenses with a thin green bezel; fins milky and frosted with thin veins; near-white studio, soft floor shadow. The order: measure the reference's main proportions as shares of its length before you build. Write a 10 to 12 line checklist of what this picture stands on. Render a still posed like the reference, put the reference and your still side by side, and grade every line yes, partial or no against the picture, not against what you remember building. Count the share of dark pixels (luma under 80) in both bounding boxes; yours has to reach 0.8 of the reference's. Fix and repeat for at least 2 rounds. The page: the shark in the middle, an invented product name and title, one pill button per part (the eye, the hammer, the flank, the jaw, the pectoral fin) that takes that part apart, and live cards that move with the parts. On load it plays a film of about 21 seconds and loops: frame 0 is the front 3/4 hero view with the shark big and already swimming; every 2 to 3 seconds a part opens in about 1 s, holds with its parts still spinning and closes in 0.5 s, each with its own camera side, height and distance, pushing in on that part; then a full explode on a 330 degree turntable, a fast reassembly while it turns, and an exit. Smooth camera paths only. Save the reference, your stills and the grades next to the page. It should look like a product film the moment it loads.
