Method Details

toPolygon

public static ConvexPolygon3D toPolygon(Collection<Vector3D> vertices,
 Vector3D normal,
 org.apache.commons.numbers.core.Precision.DoubleEquivalence precision)

Construct a ConvexPolygon3D from the given facet vertices and optional normal. If the normal is non-null, this method attempts to honor it by making the polygon point in a similar (but not necessarily equal) direction, reversing the order of vertices if needed.

Parameters:

vertices - facet vertices

normal - facet normal; may be null

precision - precision context used for floating point comparisons

Returns:

convex polygon constructed from the vertices and normal

Throws:

IllegalArgumentException - if a valid convex polygon cannot be constructed

toPolygon

public static ConvexPolygon3D toPolygon(FacetDefinition facet,
 org.apache.commons.numbers.core.Precision.DoubleEquivalence precision)

Construct a ConvexPolygon3D from the vertices of the given facet. This method attempts to honor any normal defined for the facet by making the polygon point in a similar (but not necessarily equal) direction by reversing the order of vertices if needed.

Parameters:

facet - facet to convert to a polygon instance

precision - precision context used for floating point comparisons

Returns:

convex polygon constructed from the facet

Throws:

NullPointerException - if either argument is null

IllegalArgumentException - if a valid convex polygon cannot be constructed
