Rotate(Double,Coordinate2D) Method

In This Topic

Rotates the Coordinate2D around an axis defined by another Coordinate2D.

Syntax

C#
Visual Basic (Declaration)

public void Rotate( 
   double angle,
   Coordinate2D axis
)

Public Overloads Sub Rotate( _
   ByVal angle As Double, _
   ByVal axis As Coordinate2D _
)

Parameters

angle: The angle in radians defining the rotation.
axis: The axis around which the Coordinate2D is rotated.

Exceptions

Exception	Description
System.ArgumentException	angle is NaN.

Remarks

The Coordinate2D is rotated a given input angle measured in radians around the specified axis defined by the input Coordinate2D.

Example

2D Vector Operations

Coordinate2D v = new Coordinate2D(0, 1);
// v.Magnitude = 1

Coordinate2D other = new Coordinate2D(-1, 0);
double dotProduct = v.DotProduct(other);
// dotProduct = 0

Coordinate2D w = v + other;
// w = (-1, 1)

w += other;
// w = (-2, 1)

w -= other;
// w = (-1, 1)

w = v;
w.Rotate(Math.PI, other);
// w = (-2, -1)

w = other;

w.Scale(-4);
// w = (4, 0)
// w.Magnitude = 4

w.Move(-1, 4);
// w = (3, 4)
// w.Magnitude = 5

w.Move(-6, -1);
Tuple<double, double> components = w.QueryComponents();
// components = (-3, 3)
// w.Magnitude = 3 * Math.Sqrt(2)

Coordinate2D unitVector = w.GetUnitVector();
// w = (-Math.Sqrt(2) / 2, Math.Sqrt(2) / 2)
// w.Magnitude = 1


w.SetComponents(3, 4);
