The invention relates to a method for texturizing virtual three-dimension al objects, particularly virtual three-dimensional building objects and city models with a photographic image (1) of a real object, particularly of a pi cture of a façade. The method is characterized by the following steps: Proje cting the photographic image (1) onto a virtual surface (2) of the virtual t hree-dimensional object to produce a raw texture; localizing a raw texture e lement (3) in the raw texture by using a classification method; computer-com patible description of the localized raw texture element by a formal feature set for the raw texture element, particularly a feature vector; comparing t he formal feature set of the raw texture element with each feature set of pr edefined library elements (4), and determining degrees of similarity between the raw texture element and each library element; replacing the localized r aw texture element with at least one library element when a predefined degre e of similarity is present, and reshaping the raw texture into a generalized texture (5) of the virtual object by replacing all raw texture elements wit h library elements.
