[away3d] Matrix multiplication in 3.6

[fab4ce]

how do write this in Away3D 3.6 ?


function rotateMatrix(object:Object3D, x:Number, y:Number):void{
    var rot1:Matrix3D=new Matrix3D();
    var rot2:Matrix3D=new Matrix3D();
    rot1.rotationMatrix(0,1,0,x);
    rot2.rotationMatrix(1,0,0,y);
    rot1.multiply(rot1, rot2);
    rot1.multiply(rot1,object.transform);
    object.transform = rot1;
}
