Examples

JScript Example

var oRotation = XSIMath.CreateRotation( XSIMath.DegreesToRadians( 90 ), 0, 0 ) ;

var oQuaternion = XSIMath.CreateQuaternion() ;
oRotation.GetQuaternion( oQuaternion ) ;

Application.LogMessage( "Quaternion for 90 degree x rotation is " 
              + oQuaternion.W + "," 
              + oQuaternion.X + "," 
              + oQuaternion.Y + "," 
              + oQuaternion.Z ) ;

//Output:
//INFO : Quaternion for 90 degree x rotation is 0.7071067811865476,0.7071067811865475,0,0
