		double	s1x,
		double	s1y,
		double	s2x,

Look if the two segments cross.

bool vmal_operators::line_cross_seg	(	vnl_double_3	start_seg,
		vnl_double_3	end_seg,
		vnl_double_3 &	line_equ,
		vnl_double_3 &	inter,
		double &	alpha
	)		`[static]`

Compute the crossing point "inter" of a segment and a line.

alpha is the angle between the two. It returns true iff the line crosses the segment inside [start_seg,end_seg].

double vmal_operators::project_point	(	double	x0,
		double	y0,
		double	ax,
		double	ay,
		double	bx,
		double	by,
		double *	x,
		double *	y
	)		`[static]`

Project the point (x0,y0) on the segment [(ax,ay),(bx,by)].

(x,y) is the projected point. It returns the orthogonal distance. (x,y)=(-1,-1) if the projected point does not belong to the segment.

bool vmal_operators::project_point	(	vnl_double_3 &	x,
		vnl_double_3 &	a,
		vnl_double_3 &	b,
		vnl_double_3 &	px
	)		`[static]`

Project the point x on the segment [a,b].

px is the projected point. It returns the orthogonal distance. px=(-1,-1) if the projected point does not belong to the segment.
