Module animation_timing 

Animation timing helpers for embedded transitions.

Provides interval remapping, table-based cubic easing samples, and the moook spatial interpolation curve used for stack push/pop motion.

Constants

DEFAULT_DURATION_MS

Default single-animation duration.

FRAME_INTERVAL_MS

Target frame interval at 30 Hz.

MOOOK_DURATION_MS

interpolate_moook_duration() (3 in + 4 out frames).

NORMALIZED_MAX

Normalized animation progress maximum (16-bit).

PORT_HOLE_DURATION_MS

PORT_HOLE_TRANSITION_DURATION_MS / ROUND_FLIP_ANIMATION_DURATION_MS.

SHUTTER_DURATION_MS

SHUTTER_TRANSITION_DURATION_MS (2 + 4 frames).

Functions

interpolate_moook

Full moook spatial interpolation (interpolate_moook).

interpolate_moook_soft

Moook with linear middle segment (interpolate_moook_soft).

moook_curve

Map linear progress t in [0, 1] through moook spatial easing to [0, 1] (may overshoot).

moook_duration_ms

moook_in_duration_ms

moook_out_duration_ms

moook_soft_duration_ms

table_ease_in_sample

Table-based cubic ease-in sample (32-entry lookup).

timing_clip

Clip normalized progress to [0, NORMALIZED_MAX].

timing_half_phase

Two-phase helper: first half / second half of a transition (port-hole, shutter, round window).

timing_scaled

Remap normalized progress into [interval_start, interval_end].

timing_shutter_phase

Shutter timing: first 2/6 then 4/6 of total duration.
