Constructor & Destructor Documentation

GreatCircleArc::GreatCircleArc (   )

Create a bad great circle arc. draw() won't do anything and squareDistance() will return the maximum float.

GreatCircleArc::GreatCircleArc (  double  startLat, double  startLong, double  endLat, double  endLong, ViewState &  m_viewState )

Create a great circle arc. Parameters: startLat  lattiude of the first point in degrees. startLong  longitude of the first point in degrees. endLat  lattide of the second point in degrees. endLong  longitude of the second point in degrees. Todo: don't check the +/- 180 degree boundary when projection does not break there.

Member Function Documentation

void GreatCircleArc::draw (  bool  withCross = true  )  const

Draw the great circle arc on the fast preview. Todo: It is probably more apropriate to use thin rectangles than lines. There are hardware defined limits on what width a line can be, and the worst case is the hardware only alows lines 1 pixel thick.

double GreatCircleArc::getxscale (   )  const

float GreatCircleArc::squareDistance (  hugin_utils::FDiff2D  point  )  const

Return the square of the minimal distance between the great circle arc and a coorinate on the panorama. This is an approximation, but should be reasonable.
