C++ (Cpp) Angle::as_delta Examples

Example #1

File: dlgWayPointSelect.cpp Project: hnpilot/XCSoar

static void
OnTimerNotify(WindowControl * Sender)
{
  (void)Sender;
  if (filter_data.direction_index == 1) {
    Angle a = last_heading - XCSoarInterface::Basic().Heading;
    if (a.as_delta().magnitude_degrees() >= fixed_one) {
      UpdateList();
      InitializeDirection(true);
      wpDirection->RefreshDisplay();
    }
  }
}

Example #2

File: AATPoint.cpp Project: Mrdini/XCSoar

void
AATPoint::get_target_range_radial(fixed &range, fixed &radial) const
{
  const fixed oldrange = range;

  const GeoPoint fprev = get_previous()->get_location_remaining();
  const GeoPoint floc = get_location();
  const Angle radialraw = (floc.bearing(get_location_target()) -
      fprev.bearing(floc)).as_bearing();

  const fixed d = floc.distance(get_location_target());
  const fixed radius = floc.distance(get_location_min());
  const fixed rangeraw = min(fixed_one, d / radius);

  radial = radialraw.as_delta().value_degrees();
  const fixed rangesign = (fabs(radial) > fixed(90)) ?
      fixed_minus_one : fixed_one;
  range = rangeraw * rangesign;

  if ((oldrange == fixed_zero) && (range == fixed_zero))
    radial = fixed_zero;
