Scale Method—ArcGIS Pro

Scales the Coordinate3D by the given factor.

Syntax

C#
Visual Basic (Declaration)

public void Scale( 
   double scaleFactor
)

Public Sub Scale( _
   ByVal scaleFactor As Double _
)

Parameters

scaleFactor: The factor by which to scale.

Remarks

Each component of the Coordinate3D is multiplied by . If the scale factor is positive, the direction is not changed. If the scale factor is negative, the direction is opposite the original direction. The Magnitude of the scaled Coordinate3D = original magnitude * Abs().

Scale

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
