    Rotate Method (Coordinate3D)
    In This Topic
    Rotates the Coordinate3D around an axis defined by another Coordinate3D. The angle is in radians.
    Syntax
    public void Rotate( 
       double angle,
       Coordinate3D axis
    )
    Public Sub Rotate( _
       ByVal angle As Double, _
       ByVal axis As Coordinate3D _
    ) 

    Parameters

    angle
    The angle defining the rotation.
    axis
    The axis around which the Coordinate3D is rotated.
    Remarks
    The Coordinate3D is rotated a given input angle measured in radians around the specified axis defined by the input Coordinate3D. To rotate a Coordinate3D in a given plane defined by two Coordinate3D, use the CrossProduct of those coordinates as the axis of rotation.
    Example
    Vector Operations
    // Easy 3D vectors
    Coordinate3D v = new Coordinate3D(0, 1, 0);
    // v.Magnitude = 1
    
    Coordinate3D other = new Coordinate3D(-1, 0, 0);
    // other.Magnitude = -1
    
    double dotProduct = v.DotProduct(other);      // dotProduct = 0
    
    Coordinate3D crossProduct = v.CrossProduct(other);
    // crossProduct.X = 0
    // crossProduct.Y = 0
    // crossProduct.Z = 1
    
    Coordinate3D addVector = v.AddCoordinate3D(other);
    // addVector.X = -1
    // addVector.Y = 1
    // addVector.Z = 0
    
    // Rotate around x-axis
    Coordinate3D w = v;
    w.Rotate(Math.PI, other);
    // w.X = 0
    // w.Y = -1
    // w.Z = 0
    
    w.Scale(0.5);
    // w.X = 0
    // w.Y = -0.5
    // w.Z = 0
    
    w.Scale(-4);
    // w.X = 0
    // ww.Y = 2
    // w.Z = 0
    // w.Magnitude = 2
    
    w.Move(3, 2, 0);
    // w.X = 3
    // w.Y = 4
    // w.Z = 0
    // w.Magnitude = 5
    
    
    Coordinate3D emptyVector = new Coordinate3D();
    // emptyVector = (0, 0, 0)
    emptyVector.SetEmpty();
    // emptyVector = (Nan, Nan, Nan)
    
    Coordinate3D c1 = new Coordinate3D(2, 3, 4);
    Coordinate3D c2 = new Coordinate3D(9, -1, 3);
    
    var result_add = c1 + c2;
    // result_add = (11, 2, 7)
    var result_sub = c1 - c2;
    // result_sub = (-7, 4, 1)
    
    var b = result_sub != result_add;
    // b = true
    
    result_add = emptyVector + c1;
    // result_add = (Nan, Nan, Nan)
    
    b = result_add == emptyVector;
    // b = true
