Create from scratch a fully interactive 3D scene of a traditional wooden riverboat being poled upstream through a mountain river valley in feudal Japan during cherry-blossom season. The visual style should be cinematic and painterly rather than photorealistic, while still being exceptionally rich, detailed, polished, and visually sophisticated.
Build the valley terrain, river, riverbanks, rocks, cherry trees, maples, pines, forest, ground cover, temple architecture, boat, boatman, villagers, sky, clouds, distant mountains, lighting, materials, water, reflections, petals, mist, particles, wildlife, weather, a full day-and-night cycle, sound, animation, camera work, composition, atmospheric depth, and color grading. The final result should feel like a premium, high-production 3D artwork, not a prototype, technical demo, or low-quality scene.
Start from a completely blank page. Do not reuse or depend on any previous project or scene. You may create the assets yourself or use reliable, trusted, open-source assets and libraries when necessary.
Mandatory requirements:
No text of any kind may appear anywhere inside the scene, including the loading screen. No titles, names, logos, descriptions, credits, labels, or control instructions in any language. Any loading indicator must be purely graphic.
Deliver the entire project as one final standalone page file that can be opened directly in a web browser, with assets embedded inside it as much as reasonably possible and no runtime requests to external CDNs.
The valley must feel like one continuous, believable place. A winding river flows down a long valley that narrows into a gorge upstream. It has a deep channel and shallow pebbled margins. Its banks vary between gravel bars and steeper earthen banks. Forested valley walls rise into rounded mountains, and far ranges fade layer by layer into haze.
Build these landmarks along the river:
- An arched vermilion wooden bridge on piers that stand in the water.
- A torii gate at the bridge's end.
- A path to stone steps and a temple terrace held up by dry-stone retaining walls.
- A main hall with a curved tile hip-and-gable roof, upturned corners, bracket sets, a railed veranda, and lattice doors.
- A five-storey pagoda with a ringed spire on a knoll.
- Stone lanterns along the approach.
- A small wayside shrine in a clearing on the far bank.
- A tunnel of small vermilion torii climbing the bank upstream to a hillside shrine.
- A rope fence with paper streamers.
- Bells hanging from the roof corners that swing in the wind.
For vegetation, place hero cherry trees by hand, including a weeping cherry. Give them gnarled, leaning trunks, let some overhang the water, and cover them in dense blossom. Ad
