convert the uploaded image into a clean accurate 3d model of the picture frame only preserve the exact rectangular proportions and front facing shape model the continuous twisted rope molding around the outer perimeter the wide smooth beveled central band and the thin stepped molding around the inner opening give the frame realistic depth and thickness keep the geometry symmetrical with clean 45 degree mitered corners the centre must remain completely open use smooth simplified surfaces with no painting glass backing panel wall wood grain scratches or surface texture create one isolated watertight architectural object with clean geometry and a moderate polygon count
