soft-blob-touch: HyperFrames video primitive (product demo / material)
|
||||
|
||||
A granular soft blob idles with slow internal drift; a scripted touch dot
|
||||
decel-arrives at a caller-positioned point; the blob deforms toward it
|
||||
(an attraction bulge with mass), then recovers with an interruptible
|
||||
spring once the dot retreats. The AI-orb material beat. Softness is the
|
||||
whole point: the body is layered radial gradients plus a seeded grain
|
||||
field, and nothing in the frame has a hard edge.
|
||||
|
||||
Reference: alexwidua 1702356241186476225 sheet-02 (granular blob leaning
|
||||
toward a finger; fuzzy boundary, mass, recovery wobble).
|
||||
|
||||
Variables (declared in data-composition-variables below):
|
||||
- touch_x, touch_y (numbers, percent of host box): where the dot lands.
|
||||
- touch_at (seconds): when the dot makes contact. Clamped so the whole
|
||||
deform and recover tail stays inside the clip.
|
||||
- grain ("fine" | "coarse"): speck count and size for the body.
|
||||
- accent ("green" | "blue" | "violet"): green rides --brand, blue rides
|
||||
--accent, violet rides --accent-2.
|
||||
- exit ("none" | "fade" | "up"): default none, the settled blob holds.
|
||||
|
||||
Envelope, fixed IN and OUT with elastic HOLD only (never timeScale):
|
||||
IN ends when the recovery spring settles (touch_at + 1.57s); HOLD is
|
||||
dead still (drift completes integer sine cycles and ends at exactly
|
||||
zero by then); OUT = 0.45s only when exit is not none.
|
||||
|
||||
Deformation model (law L1, interruptible spring):
|
||||
Two plain-object params (bulge, lean) feed ONE onUpdate painter. The
|
||||
attack tween is the first 75 percent of a power2.out lean-in, cut
|
||||
mid-flight when the dot lifts (analytic cut: the junction value AND
|
||||
velocity are computed in closed form). The recovery tween's ease is a
|
||||
closed-form underdamped spring whose initial velocity equals the cut
|
||||
velocity, so the redirect preserves momentum exactly. Both tweens have
|
||||
explicit endpoints; any seek order lands identical values.
|
||||
|
||||
Determinism (canvas 2D law, per particle-image-reveal):
|
||||
One grain table is computed exactly once at build from fixed LCG seed
|
||||
0x50f7b10b. Every painted frame is a pure function of (table, params,
|
||||
timeline time). onUpdate clears and redraws from scratch; no
|
||||
Math.random, no wall clock, no incremental state. Eventful seeks
|
||||
(suppressEvents false) repaint identically in any order.
