“Passive documentation”based on the scanning and storing of raw unprocessed clouds of points in all forms of depositories.
Once acquired, the cloud of points can be processed in the future by other, more capable means, and the documentation future by other, more capable means, and the documentation
can be prepared when required.
It can be the object of various forms of processing or morphing, th ti it f th i ti t b i th l li itthe creativity of the scientist being the only limit.
The process of modifying clouds of points is long and time-consuming.g
It is estimated, that the mere scanning, that is the acquisition of the point cloud; constitutes about 10-20% of the entire work
necessary for standard documentationnecessary for standard documentation.
