Digital information recording is the basis of virtual representation, transformation and analysis for multi-form-dimension objects. In the process of building virtual worlds, recording the spatial and colorific attributes of the multiform-dimension objects is always a hard, but very important job. Taking the heritages of Dunhuang Art Cave as examples, the integrated technology of digital information recording for multiform-dimension objects is discussed. In addition, according to the specialties of the representative heritages of Dunhuang Art Cave, the methods and cri-terions for recording murals and painted sculptures are proposed, that can satisfy the requirements of the high-preci-sion documentation and representation of digital heritages.
