Multiplies this point by a scalar value, resulting in a new point whose coordinates are the product of the respective coordinates of this point and the scalar.
Multiplies this point by a scalar value, resulting in a new point whose coordinates are the product of the respective coordinates of this point and the scalar.
Value parameters
- scalar
-
scalar value to multiply the point by.
Attributes
- Returns
-
a new Point2D representing the scaled point.
Adds two points together, resulting in a new point whose coordinates are the sum of the respective coordinates of the two points.
Adds two points together, resulting in a new point whose coordinates are the sum of the respective coordinates of the two points.
Value parameters
- other
-
the other point to add.
Attributes
- Returns
-
a new Point2D representing the sum of this point and
other.
Subtracts another point from this point, resulting in a new point whose coordinates are the difference of the respective coordinates of the two points.
Subtracts another point from this point, resulting in a new point whose coordinates are the difference of the respective coordinates of the two points.
Value parameters
- other
-
the other point to subtract.
Attributes
- Returns
-
a new Point2D representing the difference of this point and
other.
Computes the Euclidean distance between this point and another point.
Computes the Euclidean distance between this point and another point.
The Euclidean distance is calculated as:
sqrt((x2 - x1)^2 + (y2 - y1)^2)
Value parameters
- other
-
the other point to which the distance is measured.
Attributes
- Returns
-
the Euclidean distance between this point and
other.
Calculates the dot product of this point with another point.

Value parameters
- other
-
the other point to compute the dot product with.
Attributes
- Returns
-
the dot product as a
Double, which is the sum of the products of the corresponding coordinates.
Calculates the magnitude (length) of this point vector.
Calculates the magnitude (length) of this point vector.
Attributes
- Returns
-
the magnitude as a
Double, which is the square root of the sum of the squares of the coordinates.
Normalizes this point to a unit vector.
Normalizes this point to a unit vector.
Attributes
- Returns
-
a new Point2D representing the normalized point.
The x-coordinate of this point.
The x-coordinate of this point.
Attributes
The y-coordinate of this point.
