TrySplitBy(GeoPolygon2, GeoLine2, out GeoPolygon2[], out GeoPolygon2[])

Cuts a loop by the straight line through a segment.

public static bool TrySplitBy(GeoPolygon2 polygon, GeoLine2 cutter, out GeoPolygon2[] left, out GeoPolygon2[] right)

Parameters

polygon GeoPolygon2

cutter GeoLine2

left GeoPolygon2[]

right GeoPolygon2[]

Returns

bool

TrySplitBy(GeoPolygon2, GeoLine2, out GeoPolygon2[], out GeoPolygon2[], Tolerance)

Cuts a loop by the straight line through a segment, within a tolerance.

public static bool TrySplitBy(GeoPolygon2 polygon, GeoLine2 cutter, out GeoPolygon2[] left, out GeoPolygon2[] right, Tolerance tolerance)

Parameters

polygon GeoPolygon2

The loop to cut.

cutter GeoLine2

A segment, read as the whole straight line through it; its length is ignored.

left GeoPolygon2[]

The pieces on the left of the cutter's direction of travel.

right GeoPolygon2[]

The pieces on its right.

tolerance Tolerance

The tolerance.

Returns

bool

true when the line divided the loop, leaving something on both sides; otherwise, false, and the loop comes back whole on the side it lies on.

Remarks

Left and right are read from the cutter's own direction, so reversing the cutter swaps the two answers and nothing else. A concave loop can give several pieces to a side, which is why each side is an array.

Exceptions

ArgumentNullException

Thrown when the loop is null.

TrySplitBy(GeoFace2, GeoLine2, out GeoFace2[], out GeoFace2[])

Cuts a face by the straight line through a segment.

public static bool TrySplitBy(GeoFace2 face, GeoLine2 cutter, out GeoFace2[] left, out GeoFace2[] right)

Parameters

face GeoFace2

cutter GeoLine2

left GeoFace2[]

right GeoFace2[]

Returns

bool

TrySplitBy(GeoFace2, GeoLine2, out GeoFace2[], out GeoFace2[], Tolerance)

Cuts a face by the straight line through a segment, within a tolerance.

public static bool TrySplitBy(GeoFace2 face, GeoLine2 cutter, out GeoFace2[] left, out GeoFace2[] right, Tolerance tolerance)

Parameters

face GeoFace2

The face to cut, holes and all.

cutter GeoLine2

A segment, read as the whole straight line through it; its length is ignored.

left GeoFace2[]

The pieces on the left of the cutter's direction of travel.

right GeoFace2[]

The pieces on its right.

tolerance Tolerance

The tolerance.

Returns

bool

true when the line divided the face, leaving something on both sides; otherwise, false, and the face comes back whole on the side it lies on.

Remarks

A hole the line misses stays a hole in whichever piece keeps it; a hole the line crosses opens into the outline of both pieces, which is why a face can come back with fewer holes than it went in with.

Exceptions

ArgumentNullException

Thrown when the face is null.

TrySplitBy(GeoPolygon2, GeoPolyline2, out GeoPolygon2[])

Cuts a loop in two along a chain drawn across it.

public static bool TrySplitBy(GeoPolygon2 subject, GeoPolyline2 cutLine, out GeoPolygon2[] pieces)

Parameters

subject GeoPolygon2

cutLine GeoPolyline2

pieces GeoPolygon2[]

Returns

bool

TrySplitBy(GeoPolygon2, GeoPolyline2, out GeoPolygon2[], Tolerance)

Cuts a loop in two along a chain drawn across it, within a tolerance.

public static bool TrySplitBy(GeoPolygon2 subject, GeoPolyline2 cutLine, out GeoPolygon2[] pieces, Tolerance tolerance)

Parameters

subject GeoPolygon2

The loop to cut.

cutLine GeoPolyline2

The chain to cut along. Both of its ends have to sit on the loop's boundary and everything between them has to stay inside, or nothing is cut.

pieces GeoPolygon2[]

The two pieces, or the loop alone.

tolerance Tolerance

The tolerance.

Returns

bool

true when the chain divided the loop in two; otherwise, false.

Remarks

This is the bounded cutter: the chain gives the exact line of the cut, so a piece keeps the chain's own vertices rather than a straight line between its ends. A chain that leaves the loop and comes back would divide it into more than two, so it is refused rather than answered in part.

Exceptions

ArgumentNullException

Thrown when the loop or the chain is null.

Returns

bool

true if the polygon boundary crosses the subject; false when it does not, which is not a failure: one array then holds the subject itself and the other is empty.

Remarks

A segment running along the polygon boundary counts as inside, matching Contains(GeoPolygon2, GeoPoint2, Tolerance).
