Constructor & Destructor Documentation

DiscreteLine2D::DiscreteLine2D	(	const Point &	start,
		const Point &	end
	)		[inline]

Member Function Documentation

void DiscreteLine2D::generatePointsWithBresenham	(	int	x1,
		int	y1,
		int	x2,
		int	y2
	)		[inline, private]

Creates a line segment on a grid with a Bresenham algorithm; if the World consists of cells, it is required to transform coordinates of segment in a view that is useful for this representation of the world; the result can be obtained by points() method.

Parameters:

x1,y1	Coordinates of the beginning of a line segment.
x2,y2	Coordinates of the ending of a line segment.
