01 — Snow and fur

The snow remembers.

Walk, run and jump through a snowy forest, compressing deep powder into lasting tracks. Stop to shake snow from the fur, then circle back through your own footprints. There is no score or countdown: movement, texture and observation are the experience.

This fusion combines a persistent snow field, simulated fur guides and local 3D powder in one realtime scene. The terrain is a compactable height field and visible hairs follow simulated guides; individual hairs and snow crystals are not all independently simulated.

Development: GPT-6 ASTRA PRO. This page presents DRIFT-URSUS-Fusion, built and hosted as a separate Vercel project. Built on Three.js; the single-file release embeds its runtime modules and needs no CDN.
