The Use OF Digital Technologies IN CONTEMPORY SCULPTURE. Dan Collins Professor of Intermedia Arizona State University. Two ways to begin:. Create an original pattern and scan the image (L. West at ASU Prism lab). Create the image entirely on the computer ( Rinus Roelofs ).

This 3d scanner uses a standard Canon DSLR camera combined with a Pico projector mounted on the hot shoe, and is controlled by the Mephisto 3D scan engine.

This unique approach projects a random light pattern on a person and captures a 3-D image in two thousandths of a second with synchronized digital cameras arranged around the subject at precise angles. By calculating the displacement of the light patterns, the subject's exact surface geometry and accurate surface texture map are built in seconds and then fused mathematically.

1999 the State institute for the Care of Historical Monuments in Prague with the support of the Czech Ministry of Culture began a long-term project, monitoring the Charles Bridge sculptures.
The Charles Bridge, dating from the 14th century, is not only a significant historical monument, but also a gallery of baroque sculpture.
The sculptures and sculpture groups are affected by degradation and the original objects are being gradually replaced by copies.
Non-destructive measuring methods, including a detailed photo documentation was used. To actually get the 3D form, the "flat pictures" can not give enough information. Therefore an accurate digitizing was needed, producing data which can easily be archived, compared and used for making a replica if needed.

The 6 meter high sandstone sculpture of Saint Vojtech by the 18th c. sculptor Ferdinand Maxmilian Brokoff was the first element to be digitized.
The Czech company, MCAE, utilized the optical measuring systems TRITOP and ATOS from GOM.
