Constructors

Polygon3

constructor(vertices: List<Vec3>, precision: DoubleEquivalence = DEFAULT_DOUBLE_EQUIVALENCE)

Properties

edges

val edges: List<Seg3>

normal

val normal: Vec3

The normal vector of the polygon's plane.

precision

val precision: DoubleEquivalence

vertexCount

open val vertexCount: Int

Returns the number of vertices in the polygon.

vertices

open override val vertices: List<Vec3>

Returns the list of vertices defining the polygon.

Functions

area

open override fun area(): Double

Computes the area of the polygon.

centroid

open override fun centroid(): Vec3

Computes the centroid (geometric center) of the polygon.

contains

open override fun contains(point: Vec3): Boolean

Checks if a point is inside the polygon.

dimensions

open override fun dimensions(): Int

Returns the number of dimensions of the spatial object.

isConvex

open override fun isConvex(): Boolean

Checks if the polygon is convex.

isFinite

open override fun isFinite(): Boolean

Returns true if all values in the spatial are finite.

isInfinite

open override fun isInfinite(): Boolean

Returns true if any value in the spatial is infinite.

isNaN

open override fun isNaN(): Boolean

Returns true if any value in the spatial is NaN (Not a Number).

isSimple

open override fun isSimple(): Boolean

Checks if the polygon is simple (non-self-intersecting).

perimeter

open override fun perimeter(): Double

Computes the perimeter of the polygon.

reverse

open override fun reverse(): Polygon<Vec3>

Reverses the order of vertices, effectively reversing the orientation of the polygon.

scale

open override fun scale(factor: Double, center: Vec3): Polygon<Vec3>

Scales the polygon by a given factor around a center point.

signedArea

open override fun signedArea(): Double

Computes the signed area of the polygon.

transform

open override fun transform(transformer: Transformer<Vec3>): Polygon<Vec3>

Transforms the polygon by applying a transformation to all vertices.

translate

open override fun translate(offset: Vec3): Polygon<Vec3>

Translates the polygon by a given offset vector.
