[away3d] help converting Spherical coordinates to Cartesian coordinate

[Qutaibah Hamadah]

Hello, 
I am trying to figure out hope to pass some Spherical coordinates and get 
Cartesian coordinates bask. 

I have found some examples online, but I am not able to make them work for me 
yet. 
here is what I have put together: 

public function convert(pRadious:Number=1, pTheata:Number=0, pPhi:Number=0 
):Point3D {                  
                                                
                        var r = pRadious;
                        var phi = pPhi;
                        var theta = pTheata;                                    
        
                        
                        // convert
                        var pX = r * Math.sin(theta) * Math.cos(phi);
                        var pY = r * Math.sin(theta) * Math.sin(phi);
                        var pZ = r * Math.cos(theta);                           
                                        
                        
                        return new Point3D(pX, pY, pZ);
                } // method 


I was hoping that someone can lend some help.
