Introduction:
An approach of digitally mapping of geometry of sculpture is unique in our country.
Information Technology in India has come a long way during last decade but it’s applications are yet to reach different areas of our society and one such area is heritage preservation.
Sculpture in any museum or in art gallery is the heart of the cultural-heritage of a country.

Contd…
It is always found that cultural-heritage is in constant danger due to environmental aging and man made disasters.
So a new need has been felt for the documentation and obtaining the geometrical models in this field.
Advancement of new Scanning Technologies combined with advanced Reverse Engg. tools and Rapid Prototyping has offered us an opportunity to do this.
Info-Sculpture project is an effort of IIT-Kanpur towards this direction.

Objective:
To record and archive the morphological features of heritage artifacts from the past culture,
Process these features using modern software tools and to create a knowledge based information system,
Exploring the potential of 3D vision for application in heritage or as input to virtual reality environment, and
Geometric modeling for reconstruction and regeneration of artifacts.

Kausambi School of Art: Department of Ancient History, Allahabad University
Kausambi was the capital of Vamsa and the scene of several important events in the Buddha's life. It has one of Asoka's pillar and a little further on the ruins of the Ghositarama, first built during the Buddha's lifetime. The huge ancient ramparts of the city though now all in ruins are also interesting.
Department of Ancient History, Allahabad University, has an extensive collection of the minor antiquities found at Kosambi.

Effect on Society:
The database of artifacts in digital form can be used in future modification work and replication.
The technology under study will allow artists, sculptors, archaeologists, and researchers to view, analyze, and even reproduce artifacts digitally.
The models thus created can form archives, which could be manipulated at any time to view, edit or fabricate.

The future generations will have the records in digital form which is not subject to environment decay and vulnerable for deterioration as original sculpture is and thus it would be a permanent record in years to come.
The work of this kind will be immensely helpful to the researchers in history and archeology now and in future.

Research issues:
How do you store 1000 Giga Bytes?
If we take cost Rs. 100 per GB
Total cost to store, let us say 1000 GB will be
= 1000 GB * Rs 100 per GB
= Rs. 1,00,000
And no library can afford to spend so much money for single
work. So it is proposed that 3D data must be stored centrally with Government aid.

How should the 3-D work be catalogued?
In case of 2D Images indexing may be done by catalogue
containing thumbnail images. But in case of 3D,thumbnails
should be interactive allowing the library user to examine the
work from all the angles.

Can bytes live longer than marbles?
In case of 2-D works the images can be printed on paper at
high resolution. In the event the digital archive becomes un-
readable, it can be re-constructed.
3-D models have no natural printed representation. RP technology
could be used to make physical replica but cost of such
replica is high and size of large prototype is limited also.Thus it
is important to preserve model digitally .

3D digital watermarking
There is small growing body of literature on 3D digital
watermarking as proposed for 2D images.

Piracy detection
If we have technology that will search for specific 3D
models on the web and 3D watermarking technique is
available, piracy for 3D models can then be detected.
