updraftShots

UPDRAFT's fifteen camera set-ups, as data. film.updraftFilm reads definition() on every play() and ticks the resulting cutscene runtime at a fixed 1/24 s, so retuning a shot means editing this table — never calling cutscene.play.

The cut

96 seconds, five movements, boundaries at 19 / 38 / 64 / 83.

windows() derives the per-shot windows from the durations. evaluate(t) gives the eye, the look point and the lens at any film second without playing anything — the way to check a frame while authoring.

check() — the three things that must stay true

Call it; an empty list is the pass.

1. The cut. The fifteen durations sum to Film.DURATION and the movement boundaries land on 19 / 38 / 64 / 83 exactly.
2. The repeat. Shot 12 IS shot 2's set-up — the same three tables, shared by reference, not a copy. The film turns on that frame reading as one camera in two different buildings, and a copy would let one of them be nudged and quietly break the rhyme. check() compares them with rawequal.
3. Nothing in the masonry. No camera anchor stands between shelfFace and the outer wall. The shaft is clear inside walkwayInner, the walkway runs out to shelfFace, and past innerRadius is stone.

Anchors — how to make a shot track something that moves

A shot's pos / look is a world position, a list of them the camera travels along, or the name of an entity, resolved on the frame it is drawn. Four subjects in this film would rather track than guess, and M.ANCHORS names them:

Spawn an entity under one of those names and the camera locks to it for free. Until one exists the shot frames a world position instead, so nothing is refused for naming something that has not been built yet — definition() re-resolves every anchor on every play.

Two set-ups that are deliberately not obvious

• Shot 3 dollies the Gallery 14 ring as a three-point polyline at r = 15.2, between the brass rail and the shelf face. A straight move between its two ends would cut the chord through the shelving.
• Shot 15 racks off the folio and down onto the tower as hold, rack, hold — each anchor repeated, so a third of the shot sits on the burning page, a third swings, and a third sits on the tower. A two-point look interpolates the aim point across three hundred metres of empty air and spends the middle of the shot framing neither end of it.

What this module does not own

The clock, the curves and the registry are film.updraftFilm. The sound is film.updraftSound, which shares this slice and reads M.shots directly to put the scene's Listener on the lens every frame.
