Rotation3D

constructor(heading: Double, pitch: Double = 0.0, roll: Double = 0.0)

heading

around z-axis, 0.0 = direction of x-axis / east (+π/2 = direction of y-axis / north)

pitch

around y’-axis, 0.0 = level (in x’/y’ plane), ( +π/2 = direction of negative z-axis)

roll

around x’’-axis, 0.0 = level (parallel to x’’/y’’ plane)
