Class VerticesFactory

Returns the area of the set of vertices.

Returns the centre (centroid) of the set of vertices.

Chamfers a set of vertices by giving them rounded corners, returns a new set of vertices. The radius parameter is a single number or an array to specify the radius for each vertex.

Sorts the input vertices into clockwise order in place.

Returns true if the point is inside the set of vertices.

Creates a new set of Matter.Body compatible vertices. The points argument accepts an array of Matter.Vector points orientated around the origin (0, 0), for example:

[{ x: 0, y: 0 }, { x: 25, y: 50 }, { x: 50, y: 0 }]

The Vertices.create method returns a new array of vertices, which are similar to Matter.Vector objects, but with some additional references required for efficient collision detection routines.

Note that the body argument is not optional, a Matter.Body reference must be provided.

Parses a string containing ordered x y pairs separated by spaces (and optionally commas), into a Matter.Vertices object for the given Matter.Body. For parsing SVG paths, see Svg.pathToVertices.

Returns the convex hull of the input vertices as a new array of points.

Returns the moment of inertia (second moment of area) of the set of vertices given the total mass.

Returns true if the vertices form a convex shape (vertices must be in clockwise order).

Returns the average (mean) of the set of vertices.

Rotates the set of vertices in-place.

Scales the vertices from a point (default is centre) in-place.

Translates the set of vertices in-place.
