Re: [script] Comparing two transforms

Salut Christopher ;-)


Thanks for the advice.

Right now I'm using a somewhat ugly but effective approach:



def compareTransforms( oTransform1, oTransform2 ):
    
    """
    RETURN VALUE: boolean
    """
    
    bSame = True
    
    if round( oTransform1.PosX, 4 ) != round( oTransform2.PosX, 4 ):
        bSame = False
    
    elif round( oTransform1.PosY, 4 ) != round( oTransform2.PosY
, 4 ):
        bSame = False
    
    elif round( oTransform1.PosZ, 4 ) != round( oTransform2.PosZ, 4 ):
        bSame = False
    
    elif round( oTransform1.RotX, 4 ) != round( oTransform2.RotX, 4 ):
        bSame = False
    
    elif round( oTransform1.RotY, 4 ) != round( oTransform2.RotY, 4 ):
        bSame = False
    
    elif round( oTransform1.RotZ, 4 ) != round( oTransform2.RotZ
, 4 ):
        bSame = False
    
    elif round( oTransform1.SclX, 4 ) != round( oTransform2.SclX, 4 ):
        bSame = False
    
    elif round( oTransform1.SclY, 4 ) != round( oTransform2.SclY, 4 ):
        bSame = False
    
    elif round( oTransform1.SclZ, 4 ) != round( oTransform2.SclZ, 4 ):
        bSame = False
    
    
    #~ if not bSame:
        #~ xsi.logmessage( '< bb_ReplaceModels > :: Not same transforms.', c.siWarning
 )
    #~ else:
        #~ xsi.logmessage( '   < bb_ReplaceModels > :: Same transforms.' )
    
    return bSame



I wish there was a one-liner way to do this.
