Digital cataloguing of the historical-artistic heritage with 3d scanning

The historical-artistic heritage, public or private, is unrepeatable, we have to physically and virtually preserve it, digitize with a 3d scanner to reproduce it if necessary.

 

A statuette, a vase, bracelet, furniture, mural, … that belong to the historical and artistic heritage are valuable and unique objects. Centers and Institutions that guard them are responsible for preserving from possible external affections.
Are also very important elements for their study in schools, institutes, universities, collectives, etc. It is important that it can be visited and observed with specialized professional advice.

Another way to preserve the cultural and artistic heritage is the 3D digitization of an object with all the detail and its exact form and sizes, which allows its online diffusion and digital cataloging.
Through 3D presentations, like the one that accompanies this post, the object can be interactively observed 360º around it, appreciate the details of its texture, its wear and tear caused by time and its natural colors.
Its utility for the educational and cultural community is evident. A virtual object can be shared with any collective or study Center, via the Internet, as an individual object or as part of a collection, and may be included in digital books. It can be studied remotely.

 

 

With high-definition 3D scanning and hyper-realistic texturing, we can reproduce an object in a virtual way with extreme fidelity, both in texture and colors, as well as in its exact shape and sizes, which will allow us to study any crack, relief or pigment, however small it is … well, provided it exceeds 0.1mm.

The digitized 3D object can be created with different levels of detail in its polygonal structure (quantity of polygons in 3D mesh).
A 3D mesh with a large polygonal density – hundreds of thousands or millions of polygons – will be optimal for printing in 3D with the same detail and sizes as the original object.
In contrast, a 3D mesh optimized to be used for online and real-time applications, with low polygonal density – hundreds or thousands of polygons – can be seen on a screen with all the details and color, printing it as a copy of the original object will only get an “approximation” to the form, with little detail but the correct sizes.

Some museums from all over the world use 3D technology to also disseminate the works they keep and present it to the public that visits them. Some examples with presentations on online platforms may be: Auckland War Memorial Museum, New Zealand, the Brooklyn Museum, New York, the Museum of Jaen, in Spain and others.
Some Center uses 3D presentations of some important piece of the museum as an advertising claim in its marketing strategy, to attract on foot visitors, which can admire some works at home before goin g there.
The British Museum, in London, allow even the free download of some 3D models.
