Build a renderer-neutral transition plan

Adds editorial timing semantics to renderer-neutral movement data, including tables from explodemap::transition_data() and explodemap::layout_children(). The browser only needs to interpolate the supplied anchors according to the returned order and timing columns.

Usage

build_transition_plan(
  movement,
  duration = 650,
  easing = "elastic",
  stagger = 12,
  overshoot = 1.25
)

Arguments

movement

Data frame with feature_id, original/final anchors, movement distance, and optional animation_order (positive whole numbers; fractional values are rejected, not truncated).

duration

Per-feature duration in milliseconds.

easing

Easing identifier carried to the renderer.

stagger

Delay between successive animation-order values.

overshoot

Non-negative overshoot parameter.

Value

A dragmapr_transition_plan data frame containing the movement schema plus delay_ms, duration_ms, easing, and overshoot.
