Application.LogMessage TypeName(quaternion)

2. JScript Example

/* Set and display the values of a quaternion
*/
var oQuat = XSIMath.CreateQuaternion(0.615, -0.764, -0.122, 0.152);
var vbArr = new VBArray( oQuat.Get2() );
var array = vbArr.toArray();
Application.LogMessage( "W, X, Y and Z quaterion's values: " + array[0] +","
+ array[1] +","+ array[2] +","+ array[3] );
//Expected output:
