Public Methods

public distanceTo(point: Point2D): number source

Finds the distance between this point and another point.

Params:

Name	Type	Attribute	Description
point	Point2D		Point to find the distance to.

Return:

number

Distance between the points.

Test:

Point2D #distanceTo(point)

public equals(point: Point2D): boolean source

Checks if this point and another point are equal. Returns true if the x- and y-coordinates are equal.

Params:

Name	Type	Attribute	Description
point	Point2D		Point to compare with.

Return:

boolean

Whether or not the points are equivalent.

Test:

Point2D #equals(point)

public lineTo(point: Point2D): Line2D source

Creates and returns a Line2D object using this point as the start point and another point as the end point.

Params:

Name	Type	Attribute	Description
point	Point2D		Point to be used as the end point.

Return:

Line2D

Line2D object created.

Test:

Point2D #lineTo(point)

public relativePositionToTriangle2D(oldTriangle: Triangle2D, newTriangle: Triangle2D): Point2D source

Finds the coordinates this point should have relative to a triangle.

Params:

Name	Type	Attribute	Description
oldTriangle	Triangle2D		Triangle2D object containing the triangle's old position.
newTriangle	Triangle2D		Triangle2D object containing the triangle's new position.

Return:

Point2D

Point representing the point's location relative the the triangle's new position.

Test:

Point2D #relativePositionToTriangle2D(oldTriangle, newTriangle)

public translateVec(vec: Vector2D): Point2D source

Translates the point using a vector.

Params:

Name	Type	Attribute	Description
vec	Vector2D		The vector to translate the point by.

Return:

Point2D

Point resulting from the translation.

Test:

Point2D #translateVec(vec)

public vectorTo(point: Point2D): Vector2D source

Finds the vector distance from this point to another point.

Params:

Name	Type	Attribute	Description
point	Point2D		Point to find the vector distance to.

Return:

Vector2D

Vector2D object representing the vector distance.

Test:

Point2D #vectorTo(point)
