Methods

Difference(Geometry, Geometry)

Computes a Geometry representing the closure of the point-set of the points contained in this Geometry that are not contained in the other Geometry.

public virtual Geometry Difference(Geometry a, Geometry b)

Parameters

a Geometry

The 1st Geometry

b Geometry

The 2nd Geometry

Returns

Geometry

A Geometry representing the point-set difference of Geometry's a and b.

Difference(Geometry)

Intersection(Geometry, Geometry)

Computes a Geometry representing the point-set which is common to both a and b Geometry.

public virtual Geometry Intersection(Geometry a, Geometry b)

Parameters

a Geometry

The 1st Geometry

b Geometry

The 2nd Geometry

Returns

Geometry

A geometry representing the point-set common to the two Geometrys.
