Method IsCodirectional

Namespace

Assembly

GeometryHelper.dll

IsCodirectional(GeoVector2, GeoVector2)

Determines whether two vectors point the same way, using the default tolerance.

public static bool IsCodirectional(GeoVector2 v1, GeoVector2 v2)

Parameters

v1 GeoVector2

The first vector.

v2 GeoVector2

The second vector.

Returns

bool

true if the vectors are parallel and point the same way; otherwise, false.

IsCodirectional(GeoVector2, GeoVector2, Tolerance)

Determines whether two vectors point the same way, within a tolerance.

public static bool IsCodirectional(GeoVector2 v1, GeoVector2 v2, Tolerance tolerance)

Parameters

v1 GeoVector2

The first vector.

v2 GeoVector2

The second vector.

tolerance Tolerance

The tolerance.

Returns

bool

true if the vectors are parallel and point the same way; otherwise, false.

Remarks

Parallel is not enough: two vectors along one line point either the same way or opposite ways, and this tells those apart. A vector with no length is neither, as it has no direction to compare.
