Constructor & Destructor Documentation

TPointsArray3D::TPointsArray3D	(	Int_t	n,
		Option_t *	option = ""
	)

3-D PolyLine normal constructor without initialisation. If n < 0 the default size (2 points) is set.

Definition at line 77 of file TPointsArray3D.cxx.

TPointsArray3D::TPointsArray3D	(	Int_t	n,
		Float_t *	p,
		Option_t *	option = ""
	)

3-D Point3D normal constructor. If n < 0 the default size (2 points) is set.

Definition at line 95 of file TPointsArray3D.cxx.

TPointsArray3D::TPointsArray3D	(	Int_t	n,
		Float_t *	x,
		Float_t *	y,
		Float_t *	z,
		Option_t *	option = ""
	)

3-D PolyLine normal constructor. If n < 0 the default size (2 points) is set.

Definition at line 119 of file TPointsArray3D.cxx.

Member Function Documentation

Int_t TPointsArray3D::DistancetoPrimitive ( Int_t  px, Int_t  py  )

virtual

Compute distance from point px,py to a 3-D points.

Compute the closest distance of approach from point px,py to each segment of the polyline. Returns when the distance found is below DistanceMaximum. The distance is computed in pixels units.

Definition at line 188 of file TPointsArray3D.cxx.

Int_t TPointsArray3D::SetPoint ( Int_t  n, Float_t  x, Float_t  y, Float_t  z  )

virtual

Initialize one point of the 3-D polyline. if n is more then the current TPointsArray3D size (n > fN) - re-allocate this. The new size of the object will be fN += min(10,fN/4).

return the total number of points introduced.

Definition at line 263 of file TPointsArray3D.cxx.

Int_t TPointsArray3D::SetPoints ( Int_t  n, Float_t *  p = 0, Option_t *  option = ""  )

virtual

Set new values for this 3-D polyline. return the total number of points introduced.
