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.

public RectangleLineIntersector(Envelope rectEnv)

Parameters

rectEnv Envelope

The query rectangle, specified as an Envelope

Methods

Intersects(Coordinate, Coordinate)

Tests whether the query rectangle intersects a given line segment.

public bool Intersects(Coordinate p0, Coordinate p1)

Parameters

p0 Coordinate

The first endpoint of the segment

p1 Coordinate

The second endpoint of the segment

Returns

bool

true if the rectangle intersects the segment
