User-friendly and portable 3-D recording techniques will be required. These systems will measure a range of objects of different dimensions. It will be easy to transport, easy to use, and produce accurate and visually convincing results both for guiding ongoing conservation and anastylosis efforts and for presenting archaeological materials and sites to a wider audience of non-specialists. A first goal is to register in situ all stratigraphical evidence, since archaeological fieldwork by its nature destroys this kind of information. Secondly, techniques need to be developed to record 3-D models of artefacts, mainly for cataloguing and visualisation, and of pottery sherds, sculptures and buildings, mainly for restoration and visualisation. Thirdly, the terrain of the site needs to be modelled in 3-D as such topographic data yield important information for the archaeologists and is vital for realistic visualisation.
