const

bool gdt::gdtsegment::is_horizontal

bool gdt::gdtsegment::contains

(

gdtpoint

p

)

Tests if the point p belongs to the current segment.

bool gdt::gdtsegment::intersection	(	gdtsegment	b,
		gdtpoint &	p
	)

Tests if there is an instersection point betwee this segment and segment b.
If an intersection is found, the intersection point is assigned to p, and the method returns true. Otherwise, the method returns false.

double gdt::gdtsegment::direction

(

)

Returns the angle of rotation, expressed in radians, of the current segment with respect to (0,0).

double gdt::gdtsegment::angle

(

)

Returns the angle of rotation, expressed in radians, of the current segment with respect to (0,0).

double gdt::gdtsegment::angle

(

gdtsegment

t

)

Returns the angle of rotation, expressed in radians, of the current segment with respect to segment t.

double gdt::gdtsegment::distance

(

gdtpoint

p

)
