## SIQuaternion.SetIdentity

### Description

Resets the quaternion back to the identity quaternion.

### C# Syntax

    SIQuaternion.SetIdentity();

### Scripting Syntax

    SIQuaternion.SetIdentity();

### Examples

#### 1. JScript Example

    var oQuaternion = XSIMath.CreateQuaternion() ;
    Application.LogMessage( "Uninitialized Quaternion  "
                                    + oQuaternion.W + ","
                                    + oQuaternion.X + ","
                                    + oQuaternion.Y + ","
                                    + oQuaternion.Z ) ;
    oQuaternion.SetIdentity() ;
    Application.LogMessage( "Identity Quaternion  "
                                    + oQuaternion.W + ","
                                    + oQuaternion.X + ","
                                    + oQuaternion.Y + ","
                                    + oQuaternion.Z ) ;
    //INFO : Uninitialized Quaternion  1,0,0,0
    //INFO : Identity Quaternion  1,0,0,0

#### 2. VBScript Example

    dim q1
    ' Create Quaternion.
    set q1 = XSIMath.CreateQuaternion
    q1.SetIdentity
