Rotate Method—ArcGIS Pro

Rotates the Coordinate3D around an axis defined by another Coordinate3D. The angle is in radians.

Syntax

C#
Visual Basic (Declaration)

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

// 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

Requirements

Target Platforms: Windows 10, Windows 8.1, Windows 7
