Functions related to mathematics and algebra operations.

normalizeRect()

Returns an equivalent rectangle with angle in the range [-45, 45] degrees.

function normalizeRect(rect: Rect2d): Rect2d;

normalizeEllipse()

Returns an equivalent ellipse with angle in the range [-45, 45] degrees.

function normalizeEllipse(ellipse: Ellipse2d): Ellipse2d;

normalizeVector()

Returns a new vector with norm equal to 1, with the same direction as the input vector.

function normalizeVector(vector: Vector2d): Vector2d;

addVectors()

Returns the sum of two vectors as a new vector.

addPoints()

Returns the sum of two points as a new point.

function addPoints(point1: Point2d, point2: Point2d): Point2d;

subVectors()

Returns the subtraction of two vectors as a new vector.

function subVectors(vector1: Vector2d, vector2: Vector2d): Vector2d;

subPoints()

Returns the subtraction of two points as a new point.

function subPoints(point1: Point2d, point2: Point2d): Point2d;

dotProduct()

Returns the dot product of two vectors.

function dotProduct(vector1: Vector2d, vector2: Vector2d): number;
