Camera-scale physics and representative particles. Not a hemodynamic solver. Posture changes the modeled gravity vector; sleep does not simply switch blood flow off.

🎙️ Natural Narration

🎬 Recording Studio

Tour / 60-second capture sourceRecording quality

Microphone Tour from start Prefer real MP4 Film captions

For browser narration, select a tab/screen with audio sharing. Some operating-system voices require system audio rather than tab audio. A scene film cannot directly record the browser’s speech output; it includes music, captions and an optional microphone.

Ready. Recording starts only after your click and any required capture permission.

MP4 is used only when a real MP4 encoder is available. Other recordings retain their true WebM extension and keep their original format. No file is merely renamed. Downloads remain available here even when a browser blocks automatic saving.

Procedural, anatomy-inspired educational illustration. Not a scan-derived human, a clinically validated anatomical model, a fluid-dynamics solver, or a diagnostic device.

Derived from your Cardio Atlas v2. Original 59 stops, 45 glossary terms and evidence notes are retained in the source code and available as source excerpts. Educational adaptations are labeled. Three.js r180; WebGPU/TSL with WebGL2 fallback. v4 adds radius-aware interior flight and synthetic CIMT. Network access is needed for the renderer libraries.
