Built from `13-curtain-call-brief.md`. + +## What was built + +`src/mockups/13-curtain-call/` is a five-beat scripted transition. All of it is a pure function of one +number, the beat position `p` (0 = frieze … 4 = cave), so every transition can be played forwards or +backwards, or frozen with `?beat=N&t=0..1`. + +| Beat | What you see | Transition into it | +|---|---|---| +| 1 Frieze | 04's black-figure band: Troy saga column, the horse and the infant, Just a Man, Full Speed Ahead. Caption "Troy falls". | — | +| 2 To sea | 07's low-poly sea and ship; a small redraw of 12's general chart lies bottom left as the table map, with "You are here". | 1.8 s. The figures flatten into the ground line. The band splits along that line: the top half slides up, the bottom half slides down. The 3D horizon starts **exactly on the painted ground line**: the camera pitch is solved from the layout. The line fades, and only then does the camera rise over the ship's shoulder. The chart slides in last. | +| 3 Landfall | Cyclops' Island with a cave mouth facing the camera; the ship lies off the shore. | 2.0 s. The ship sails a gentle S, the island rises from under the sea, the camera swings to frame both, and "You are here" moves to port 6 on the chart. | +| 4 Curtain | The Cyclops frieze: crew (Odysseus with the cup), the cave mouth in the rock, Polyphemus with his club, sheep. Caption "Polyphemus". | 1.2 s. The frieze drops over the sea like a curtain (ease-in-out); the chart is put away as it falls. | +| 5 Cave | 3D cave interior: firelit rock, the giant's silhouette with a glinting eye, the fire, the flock. "Back to sea" in the caption. | 1.6 s. The glow in the cave mouth fades and opens. The mouth is a real hole, masked through the whole frieze, so the 3D cave shows through it. The frieze zooms through the mouth (×16) while the cave camera moves in. | + +Controls: Play/Pause (holds each beat for 3.4 s, about 25 s in total), ← / → (also arrow keys, Space +to play), five labelled step dots, "Look: 1 · 2 · 3" with the look's name, and `?beat=1..5`, +`?look=1|2|3`, `?t=` (freeze) and `?play=1`. A jump that skips a beat, such as a dot two steps away +or "Back to sea", fades through the curtain colour in about 0.7 s instead of scrubbing through the +beats in between. Under `prefers-reduced-motion`, **every** step is that fade, and the waves slow +down. The credits footer is a grid row of its own, outside the stage, so it is visible in every beat +and every look. + +Files: `main.ts` (beats, timing, DOM choreography), `frieze.ts` (the two full-stage frieze SVGs, +split at the ground line), `figures.ts` (copied from 04, helpers exported), `scene.ts` (trimmed from 07: +sky, sea, island, ship, plus a new cave scene, palettes per look), `chart.ts` (simplified 12 chart). + +## Screenshots (1440×900) + +Look 2 (default): `screenshots/13-curtain-call-beat1.png` … `-beat5.png`. +Looks 1/3: `-beat2-look1.png`, `-beat2-look3.png`, `-beat4-look1.png`, `-beat4-look3.png`. +Mid-transition (frozen with `?t=`): `-morph.png` (1→2 at 40 %), `-morph-look1.png`, `-morph-look3.png`, +`-mid-landfall.png` (2→3 at 50 %), `-mid-curtain.png` (3→4 at 50 %), `-mid-cave.png` (4→5 at 50 %). + +**Capture note:** with the brief's `--use-gl=swiftshader`, headless Chrome often captured the WebGL +canvas blank, which looked like a black stage. `--use-angle=swiftshader --use-gl=angle +--enable-unsafe-swiftshader --virtual-time-budget=6000` captures reliably. The renderer also sets +`preserveDrawingBuffer`. + +## What works + +- **The morph is honest.** The ground line really becomes the horizon: the split happens on the line, + and the sea's horizon sits on it pixel-exact before the camera moves (`-morph*.png`). +- **The cave zoom** reads well: through the mouth you see the real 3D cave, then the frieze falls away + around you (`-mid-cave.png`). +- The curtain drop is simple and clear. All transitions sit at 1.2–2.0 s and run in reverse with ←. + +## What doesn't, or is rough + +- **Landfall framing:** in the middle of 2→3 the island rises to the *right* of the ship, then the camera + swings and it ends up behind it. That reads as a slight sideways shuffle; a fixed camera would be calmer. +- **The sun** is a large glare in the morph frames of looks 1 and 2, because the camera looks level + at the horizon there. +- **The giant** is blocky boxes. As a silhouette it is enough, but it is not pretty. +- **The 3D does not match 1440×900 exactly:** the stage is 1440×~857 and the frieze uses SVG `slice`. + It is tuned for desktop only, as briefed. Other sizes still line the horizon up, because it is + computed, but the crops will differ. +- The Play hold times were only checked in code; headless virtual time does not run the rAF loop + faithfully, and one headless Play run showed the state switching (Pause, dot 2) but not the frames. +- Beat 3 has no song chip (only an eyebrow, "year 1"). Beats 3 and 4 both point at Polyphemus, so I left + that chip off beat 3. + +## The three looks, honestly + +**Look 2, two worlds** (default) is the most legible. The terracotta frieze is a strong, clearly +"other" curtain, and the naturalistic sea is a real place, so each change of world feels like an event. +But the morph (`-morph.png`) shows the seam: clay band → blue-gold sea is a jump in palette, carried +only by the geometry of the horizon line. + +**Look 3, frieze-led** makes the morph almost seamless, because terracotta sky meets terracotta band +(`-morph-look3.png`). The sea becomes a black-figure painting come to life, which is the most +*distinctive* of the three. The cost is that the 3D sea is dark and moody, the ship is a silhouette +with little detail, and the vellum chart then looks like a foreign object (which the brief allows: +"one object on the table"). + +**Look 1, vellum throughout** is the most unified and the quietest. The pen-and-wash frieze as an +illustrated chart border is charming (`-beat4-look1.png`), and the sepia sea sits right next to the +chart. But the sepia 3D loses depth and contrast (`-beat2-look1.png`), and nothing feels like a +"curtain" any more: the transitions are less of an event. + +My read: 2 if the frieze is the punctuation, 3 if the frieze is the identity. 1 is the safest, but it +undersells the 3D. diff --git a/src/mockups/13-curtain-call/chart.ts b/src/mockups/13-curtain-call/chart.ts new file mode 100644 index 0000000..ecf39b6 --- /dev/null +++ b/src/mockups/13-curtain-call/chart.ts @@ -0,0 +1,65 @@ +// A small, simplified redraw of 12's general chart: the captain's-table map, with "You are here". +// Coordinates are 12's general chart scaled into a 320×210 card. + +const P = (x: number, y: number): [number, number] => [10 + ((x - 50) * 300) / 1050, 10 + ((y - 85) * 190) / 660]; +const PORTS: [number, number][] = [ + P(344, 277), P(404, 331), P(432, 407), P(420, 488), P(373, 552), + P(456, 498), P(543, 576), P(679, 576), P(766, 499), P(960, 400), +]; +const LOOP = P(410, 592); +const AT_SEA = P(392, 584); + +const pt = (p: [number, number]) => `${p[0].toFixed(1)},${p[1].toFixed(1)}`; +const port = (i: number) => PORTS[i]!; + +/** The ship's course on the card, as one path (12's red dashed line). */ +const COURSE = `M${pt(port(0))} Q${pt(P(380, 300))} ${pt(port(1))} Q${pt(P(440, 360))} ${pt(port(2))} L${pt(port(3))} L${pt(port(4))} + Q${pt(P(380, 600))} ${pt(LOOP)} Q${pt(P(440, 570))} ${pt(port(5))} Q${pt(P(480, 570))} ${pt(port(6))} L${pt(port(7))} + Q${pt(P(730, 560))} ${pt(port(8))} Q${pt(P(860, 530))} ${pt(port(9))}`; + +/** Where "You are here" sits: k=0 out at sea after Troy, k=1 at the first Cyclops port. */ +export function hereAt(k: number): [number, number] { + const a = AT_SEA, b = LOOP, c = port(5); + // two straight legs are close enough at this size + if (k < 0.4) { const s = k / 0.4; return [a[0] + (b[0] - a[0]) * s, a[1] + (b[1] - a[1]) * s]; } + const s = (k - 0.4) / 0.6; + return [b[0] + (c[0] - b[0]) * s, b[1] + (c[1] - b[1]) * s]; +} + +export function chartSvg(): string { + const [ix, iy] = P(605, 470); + const coast = `M0,0 L${pt(P(275, 85))} Q${pt(P(300, 200))} ${pt(P(290, 300))} Q${pt(P(390, 400))} ${pt(P(375, 430))} Q${pt(P(330, 520))} ${pt(P(285, 550))} Q${pt(P(240, 680))} ${pt(P(200, 745))} L0,210 Z`; + const ports = PORTS.map((p, i) => `${i + 1}`).join(""); + let rhumbs = ""; + for (let i = 0; i < 16; i++) { + const a = (i / 16) * Math.PI * 2; + rhumbs += `M206,48 L${(206 + Math.cos(a) * 260).toFixed(0)},${(48 + Math.sin(a) * 260).toFixed(0)} `; + } + let spiral = ""; + for (let r = 3; r < 15; r += 3) spiral += ``; + return ` + + + + + + + + + + ${spiral} + + ${ports} + Troy + Cyclops' Island + two years at sea + + + + + + You are here + + + `; +} diff --git a/src/mockups/13-curtain-call/figures.ts b/src/mockups/13-curtain-call/figures.ts new file mode 100644 index 0000000..3bc96b8 --- /dev/null +++ b/src/mockups/13-curtain-call/figures.ts @@ -0,0 +1,269 @@ +// Copied from 04-greek-frieze/figures.ts (mockups never import across folders); helpers exported for 13. +// Black-figure painting kit: glaze (fill: var(--ink)) with "incised" detail lines scratched back to the clay (stroke: var(--inc)). +// Every panel shares one 300-unit-tall coordinate space with the ground line at GROUND. + +export const PANEL_H = 300; +export const GROUND = 284; + +type Arms = "spear" | "open" | "down" | "raise" | "reach" | "mourn" | "club" | "throw"; +interface Person { + x: number; y?: number; s?: number; f?: 1 | -1; arms?: Arms; + helmet?: boolean; shield?: boolean; robe?: boolean; cyclops?: boolean; kneel?: boolean; + beard?: boolean; infant?: boolean; cup?: boolean; +} + +export const g = (t: string, body: string) => `${body}`; +export const inc = (d: string, w = 1.6) => ``; +export const ink = (d: string) => ``; +// A limb: glaze stroke over a wider clay stroke, so it reads as incised where it crosses glaze. +export const limb = (d: string, w = 6) => + ``; + +export function person(p: Person): string { + const { x, y = GROUND, s = 1, f = 1, arms = "down" } = p; + const lift = p.kneel ?
