    • createNewInstance

      public Vector2D_F64 createNewInstance()
      Description copied from class: GeoTuple

      Creates a new tuple instance of the same type.

      Specified by:
      createNewInstance in class GeoTuple<Vector2D_F64>
      Returns:
      new tuple instance.

    • copy

      public Vector2D_F64 copy()
      Description copied from class: GeoTuple_F64
      Generic copy routine. It is recommended that this be overridden with a faster implementation.
      Overrides:
      copy in class GeoTuple_F64<Vector2D_F64>
      Returns:
      An exact copy of this GeoTuple.

    • setTo

      public Vector2D_F64 setTo(Vector2D_F64 src)
      Description copied from class: GeoTuple
      Sets this equal to 'src'
      Overrides:
      setTo in class GeoTuple2D_F64<Vector2D_F64>
      Parameters:
      src - The tuple being copied
      Returns:
      Reference to 'this' class instance. Used to chain operations.

    • normalize

      public void normalize()
      Normalize the vector so that the f-norm is 1. Care is taken to avoid overflow

    • normalized

      public Vector2D_F64 normalized()

    • minus

      public void minus(Point2D_F64 a, Point2D_F64 b)
      In-place minus operation. this = a - b.
      Parameters:
      a - Point
      b - Point

    • dot

      public double dot(Vector2D_F64 a)
      Dot product between this and 'a' = this.x * a.x + this.y * a.y
      Parameters:
      a - A vector
      Returns:
      dot product.

    • dot

      public double dot(double x, double y)

    • acute

      public double acute(Vector2D_F64 a)
      Returns the acute angle between the two vectors. Computed using the dot product.
      Parameters:
      a - Vector
      Returns:
      Acute angle in radians between 'this' and 'a'.
