rotateX method

Vector3 rotateX(
  1. double angle
)

Rotation of the coordinate frame by angle (radians) about the x axis – the R₁ matrix of the IERS Conventions (2010), chapter 5.

Implementation

Vector3 rotateX(double angle) {
  final c = math.cos(angle), s = math.sin(angle);
  return Vector3(x, c * y + s * z, -s * y + c * z);
}
