facet-morph: HyperFrames video primitive (intros and reveals / morph)
|
||||
|
||||
Concept: a faceted low-poly mass (36 triangles, one SVG) continuously
|
||||
reshapes between three authored silhouettes (blob, mark, badge) with
|
||||
per-facet flat shading that recomputes as the vertices move. Light reads
|
||||
from the upper left: facets turned toward it lift toward a pale accent-
|
||||
tinted tone, facets turned away fall toward near-black. The register is
|
||||
the ordinaryfolk reshaping-mass beat: one calm continuous morph, no pops.
|
||||
|
||||
Wave L, unit L2. Reference: motion-reference/ordinaryfolkco
|
||||
2001090228958752945 sheet-02 (the continuously reshaping faceted mass).
|
||||
|
||||
Determinism: vertex positions are authored keyframe tables (per-silhouette
|
||||
radius, jitter, and center rows) interpolated as a PURE FUNCTION of
|
||||
timeline time. One linear driver tween owns the whole life of the mass;
|
||||
its onUpdate recomputes every vertex and every facet fill from t alone,
|
||||
so forward, backward, and shuffled seeks land byte-identical frames.
|
||||
The wobble that keeps the mass alive is built from fixed-phase sine
|
||||
terms (phases from a fixed-seed LCG, baked once at mount).
|
||||
|
||||
Paint law: facet geometry AND facet color are written as ATTRIBUTES
|
||||
(points / fill / stroke) on every update. Nothing tweens a var() color
|
||||
string and nothing relies on CSS repaint of SVG presentation properties
|
||||
under seeks. Contract tokens are resolved to concrete rgb once at mount
|
||||
(via a probe element), then mixed numerically in JS.
|
||||
|
||||
Variables (declared in data-composition-variables below):
|
||||
- forms (string, default "blob,mark,badge"): comma-separated silhouette
|
||||
sequence. Valid names: blob, mark, badge. Unknown names are dropped;
|
||||
an empty result falls back to the default sequence.
|
||||
- hold_last (boolean, default true): true decays the wobble and holds
|
||||
the final silhouette dead still; false keeps the mass slowly
|
||||
breathing between the last two silhouettes through the hold.
|
||||
- accent (green | blue | violet, default green): tint of the lit
|
||||
facets. green maps to --brand, blue to --accent, violet to --accent-2.
|
||||
- exit (none | fade | up, default none): outgoing transition. none
|
||||
holds the settled mass (frame roots own transitions).
|
||||
|
||||
Envelope (fixed IN/OUT, elastic HOLD only, never gsap.timeScale()):
|
||||
IN = 0.55s entrance + one 1.45s morph leg per silhouette step
|
||||
(0.35s dwell between legs) + 0.55s wobble decay
|
||||
HOLD = elastic = max(0, D - (IN + OUT))
|
||||
OUT = 0.45s when exit is fade or up, 0 when exit is none
|
||||
If D < IN + OUT, IN and OUT scale down together so IN + OUT == D.
|
||||
|
||||
Sync point: form-lock when the mass reaches its final silhouette
|
||||
(3.95s at the 3-form default). Dispatches a bubbling hf:sfx CustomEvent
|
||||
with id "facet-settle-soft" there. This primitive never plays audio.
|
||||
|
||||
Mount contract: MOUNTABLE SUB-COMPOSITION. The runtime clones only
|
||||
<template> contents; #root fills the host box (inset:0, container-type:
|
||||
size), has no data-width/data-height, and registers one paused timeline
|
||||
under the literal "facet-morph" key. Variables come from
|
||||
window.__hyperframes.getVariables().
