lerp static method

PositionUnit lerp(
  1. PositionUnit a,
  2. PositionUnit b,
  3. double t
)

Linearly interpolates between two position units.

Returns a when t is 0.0, b when t is 1.0, and a blend of both for values between 0.0 and 1.0.

Implementation

static PositionUnit lerp(PositionUnit a, PositionUnit b, double t) {
  if (t <= 0.0) return a;
  if (t >= 1.0) return b;
  return a * PositionFixed(1.0 - t) + b * PositionFixed(t);
}
