NVIDIA and Artec join forces to demonstrate scanned models of ancient religious memorial stones in 3D stereo, enabling spectators to dive into medieval culture at the Tatev monastery in Armenia.
In October 2010, Artec Group, a manufacturer of high-quality 3D scanners, was invited to a picturesque village in Armenia called Tatev. The company’s aim was to scan fragments of ancient religious history – beautifully carved memorial stones known as khachkars, which are typically found around monasteries and showcase its results later at a cable car opening ceremony leading to the medieval Tatev monastery.

Located on a mountaintop, the village houses the Tatev monastery, a valuable heritage site of Armenian culture, whose construction dates back to the 9th century. Difficult to reach by any means of transportation, the religious site suffers from a declining number of visitors. A cultural program was launched, “Revival of Tatev”, which includes building the world’s longest cable car allowing both tourists and residents to reach the monastery in a little over 11 minutes. Artec Group was invited to showcase its 3D khachkari scanning results at the cable car opening ceremony.
Scanning one of those famous memorial stones, which were of 2 meter height each, took less than an hour. The front side of a khachkar is a detailed relief, including miniature sculptures, intricate compositions and decorations made of stone. To improve its 3D results, Artec used an MHT scanner that is specifically designed to capture exact shapes in lively colour.
“The results we received from scanning these khachkars were amazing” – said Artec’s Managing Director, Andrey Klimov, “Artec MHT scanners captured every detailed leaf and crevice in high-resolution colour. In future these models will, without doubt, serve as a great foundation for a comprehensive 3D museum. For the ceremony we didn’t know how to present the khachkars without losing their true dimensional accuracy. What good is a 3D image on a 2D screen?”
From all possible presentation methods out there, Artec opted for a stereoscopic demonstration of received 3D models. As Artec software programmers work with Open GL, the only way to showcase results in 3D stereo was to use the professional graphic card NVIDIA Quadro.
“The feedback was incredible” – said Artec’s Managing Director, Andrey Klimov – “guests raved about the quality of the scan, the beauty of the stones, and of how real the 3D content felt. They said, they had the feeling that they were standing right in front of the khachkar, as if they could reach out and almost touch it.”
The projection was as real as it gets: together with NVIDIA, Artec not only preserved essential Armenian history in Tatev, but was able to demonstrate its virtual achievement the way it deserved to be experienced.
Artec decided that success was worth duplicating: “The results we achieved with NVIDIA’s stereo visualisation technology showed us how to make the most of our 3D scans. The idea to include this feature into our standard software Artec Studio™ seemed a logical continuation”, announced Andrey Klimov.
Shortly after the event, Artec’s software started supporting the 3D stereo visualisation feature. Artec Studio 0.7 enables its users to showcase their models in 3D stereo. With a NVIDIA Quadro video card, all there is left to do is to get a 3D-enabled projector and glasses to experience captured scanning results coming alive.
