morphDragScale function

double morphDragScale(
  1. double recede,
  2. double arm
)

The container scale of a live drag: a subtle recede into the hand, deepened by the arm cue. Shared by the shuttle and the settled route page for the same reason as morphDragScrimFactor.

Implementation

double morphDragScale(double recede, double arm) {
  return 1 - 0.08 * recede - 0.05 * arm;
}
