This enables researchers to study and compare details such as brush stroke on paintings, images carved on an archaeological find, tool marks on a sculpture or to monitor changes in an object at different points in time. The following examples illustrate these applications. The Wand contains 60 faces carved into the surface - all with different features. Using the software, a researcher can zoom in to examine, measure or print features on each face of interest. Similar to the use raking light to examine details on works of art, the light editing tool can be used to examine details on the 3D models.
Researchers can interactively move the light source to any angle to examine features.
As demonstrated in 3D Imaging of Paintings , a unique feature of the technology for examining paintings with varnished surfaces, is that the 3D image originates from the surface of the paint layer, under the varnish, rather than from the varnish surface. Curators and art historians can use this feature to examine signatures and brush stroke details on paintings such as the following examples from a painting by Corot and on one attributed to Rembrandt. On varnished paintings, the image data originates from the surface of the paint layer under the varnish. The image data can be used to examine brush stroke and signature details on paintings. The image on the right shows the High Resolution Color Scanner digitizing a cylindrical scan on a Mayan vase.
