Polygon

A polygon is an object defined by its vertices in 2 space T is the type of the polygon and sides is how many sides the polygon has TODO: upgrade to dimension-ambiguous model class in math

class Polygon (

T

uint numSides

) {

Vector!(T, 2)[numSides] vertices;

Segment!(T, 2)[numSides] sides [@property getter];

this(Vector!(T, 2)[] vertices...);

U opCast();

bool contains(Vector!(U, 2) point);

}

Constructors

this this(): Creates an empty polygon
this this(Vector!(T, 2)[] vertices...): Creates a polygon using a list of vertices as vertices

Members

Functions

contains bool contains(Vector!(U, 2) point): Returns whether or not a given point is inside the polygon This algorithm uses scanlining (see Renderer.fillPolygon) Conceptually, it draws a ray to the left from the given point; if the ray intersects the polygon an odd number of times the point is within the polygon
opCast U opCast(): Casts the polygon to a polygon of another type

Properties

sides Segment!(T, 2)[numSides] sides [@property getter]: Gets the sides of a polygon

Variables

vertices Vector!(T, 2)[numSides] vertices;: The vertices of the polygon
