コーヒーカップから跳ねるイルカ:Three.jsのカメラフライスルー

Build a Three.js scene showing marine life inside a cup of coffee. A white ceramic cup on a saucer sits on a dark wooden table with a spoon beside it, steam rising from the surface. Dolphins and small fish leap out of the dark coffee, creating ripples and splashes. Use realistic materials for ceramic, liquid and wood, soft moody lighting and a shallow depth of field. Script a camera path with labelled stages: a counterclockwise orbit around the cup, a descent into the cup, a pass beneath the dolphins close to the liquid surface, and a final move over the rim. Add a small HUD with camera coordinates and the current stage name. Deliver one self-contained HTML file that plays the camera sequence automatically. Done means smooth camera motion and a convincing coffee surface.
