Method Summary

void	calculateCurve() Calculates the geodesic with given initial values.
int	getAngle() initial angle of geodesic in degree
PdBary	getBary() reference to barycentric coordinates of initial point
int	getElement() element on which initial point lies
double	getLength() maximum length of the geodesic
PsPanel	getSuperInfoPanel() Gets the panel of project PjImportModel.
void	init() Initializes length, angle, elementindex, geometry
boolean	load(java.lang.String fullFileName) Calls PjImportModel.load(fullFileName) and then hides the elements, triangulates, updates the number of elements, removes the previous geodesic and fits that all in the display.
void	pickInitial(PvPickEvent pos) Gets barycentric coordinates and element index from pickevent and initiates calculation of the curve.
void	start() Just calls super.start().
boolean	update(java.lang.Object event) Initiates re-calculation of geodesic if one of the parameter panels changed.
