A standalone Three.js scene at /dolly-zoom/ illustrating the dolly-zoom (Vertigo) effect: as the slider goes from 1x to 20x, the camera dollies back while the FOV narrows so the foreground person stays the same size, making the second person 100 m behind appear to grow and the surroundings compress. https://claude.ai/code/session_01RP9ampBVGD5N2FU2eABDUx
- Vendor three.module.js (r160) so the demo works without external CDN access and renders reliably in headless environments - Offset the second person 1.4 m sideways so they peek out behind the foreground subject and remain visible at every zoom level - Push side trees out to a min 8 m offset to keep a clear corridor down the path for the second person at narrow FOVs https://claude.ai/code/session_01RP9ampBVGD5N2FU2eABDUx
- preview.gif: animated 1x->20x->1x sweep (~12 fps ping-pong) - preview-strip.png: 2x3 contact sheet at 1x, 2x, 4x, 7x, 12x, 20x Useful as static previews where WebGL or an interactive page isn't available. https://claude.ai/code/session_01RP9ampBVGD5N2FU2eABDUx
Single 660 KB HTML file with three.js (r160 minified) inlined and loaded through a blob URL via dynamic import — no importmap or external network needed. Suitable for pasting into a Claude.ai conversation as an artifact. https://claude.ai/code/session_01RP9ampBVGD5N2FU2eABDUx
