direction static method

List<double> direction(
  1. double azimuth,
  2. double elevation
)

Unit world direction (East, North, Up) for an azimuth and an elevation in degrees.

Implementation

static List<double> direction(double azimuth, double elevation) {
  final a = azimuth.toRadians;
  final e = elevation.toRadians;
  return [sin(a) * cos(e), cos(a) * cos(e), sin(e)];
}
