Syntax

public class RectangleLineIntersector

Remarks

Rectangles contain a large amount of inherent symmetry (or to put it another way, although they contain four coordinates they only actually contain 4 ordinates worth of information). The algorithm used takes advantage of the symmetry of the geometric situation to optimize performance by minimizing the number of line intersection tests.

Constructors

RectangleLineIntersector(Envelope)

Creates a new intersector for the given query rectangle, specified as an Envelope.

Declaration

public RectangleLineIntersector(Envelope rectEnv)

Parameters

Type	Name	Description
Envelope	rectEnv	The query rectangle, specified as an Envelope

Methods

Intersects(Coordinate, Coordinate)

Tests whether the query rectangle intersects a given line segment.

Declaration

public bool Intersects(Coordinate p0, Coordinate p1)

Parameters

Type	Name	Description
Coordinate	p0	The first endpoint of the segment
Coordinate	p1	The second endpoint of the segment

Returns

Type	Description
bool	true if the rectangle intersects the segment
