The foremost method to consult the cun- or zun- files which contain the datasets of the White Light (WL) and Multi-spectral (MS) PLD recordings is by using the auto-running viewer interface on your PC (so-called desktop viewer): the most recent full function version is PLDviewer 7.0.05. With this viewer all viewing and analyzing features developed for the PLD system can be generated. An alternative is http://www.heritage-visualisation.org/viewer/; this is an online viewer which works from

... a browser window. It is slower (needs a sufficiently fast internet connection) and has a more number of processing abilities, mainly only those which have a pure visual nature (i.e. virtual relighting and the rendering of the various shaders). To allow consultation, viewing and analysis, for all recordings the original raw datasets have been digitized into cfd-, zun- or cun-file. Zun- and cun-files are single file datasets which conceal all the basic information in the original high definition to perform all the visual renderings and most of the analytic calculations. In the zun/cun files the original data in compressed to facilitate consultation and distribution of the datasets. For some computers and/or recordings these full frame compressed high resolution zun/cun files might be very demanding. Therefore, it has been made possible to generate results with half – or even less – of the original resolution (to perform, see sampling below).
