Hotel Bed at Dawn

A white-on-white hotel bed at dawn: one low warm sun rakes the linen while a half-open foldable shows a sunrise alarm on its cover display.

A hotel bedroom at dawn with a soft duvet, three pillows, a padded headboard, a cup on its saucer and glass doors, lit by one low warm sun that leaves deep soft shadows in the linen folds. One unhurried 13 s take in four beats: a low macro slide across the folds, a close hold, a rise over the cup with long shadows, then a pull out and drift.

    REALISM HOTEL — "Hotel bed at dawn" (see SCENE.md)

    The white-on-white member of the realism series: a hotel bed at dawn, one low warm sun through the
    glass doors, almost everything in frame white — the duvet, three pillows, the headboard, a cup on its
    saucer — so the tests are cloth sheen at a grazing sun, deep (never black) shadows in the folds,
    white-on-white bounce, a warm sun against a cool room, and a tone curve that keeps the whites apart.

    WORLD  cayley_interior_2k mounted as a grounded dome (height 1500, radius 6000): its glass doors sit
           at +x, so every shot that looks +x has the window behind the bed.
    SUN    the HDR has no sun disc (an overcast morning), so the sun is ours: a directional light 11° up at
           azimuth +20° (from +x toward +z) — inside the HDR's glass doors, which span about -45..+45°
           round +x — direction (0.922, 0.191, 0.336). Shadows fall toward -x / -z: toward the camera.
    LINEN  built, not generated: linen/build_linen.py writes models/rh-linen.glb (folds, swells, a fine
           wrinkle, the roll and the hanging drop; see its header). Props sit in the shallow dishes it
           presses under them; linen/place.py prints every rest y below (y = the highest linen point
           under the prop's underside, minus how far it sinks in).
    PROPS  TRELLIS returned no mesh (refused for the shared Runware balance, then 500 / 429 / timeouts
           after the top-up: models.log), so the cup, pillow, glasses and lamp are built meshes from linen/build_props.py at their real sizes, scale 1; the
           book and the key card are primitives. Two TRELLIS jobs landed late: the nightstand and the rolled duvet.
    SCREEN Aubade, a fictional dawn alarm for travellers, on the cover display of the half-open fold
           (realism-hotel.screens.html → scripts/html-screens.mts): 06:40 ringing, slid away at 4.2 s,
           then "Good morning" and today's two things arriving in order. No idle pulse on the alarm: the
           path tracer rebuilds its BVH on every frame a screen animates, and a pulse running from 0 s
           exhausted its memory at frame 179 of the first traced export; the screen moves 4.2–6.5 s only.
    TONE   output tone_mapping=neutral, authored: the brief asks for whites kept apart, and the traced
           render takes no `realism=tone`. PBR Neutral leaves values under ~0.8 alone (the screen holds)
           and rolls the sunlit linen off instead of clipping it. No authored fog (it would flatten the
           grounded dome in the path tracer); haze is the render-time `haze` word.
