Far more detailed than even the best photograph, these models provide incredibly accurate, realistic views of every aspect
of a particular site, giving them numerous applications in educational and cultural tourism settings. CyArk’s model of
Mt. Rushmore, for example, allows viewers to see the individual chisel marks on Teddy Roosevelt’s mustache.
Bouncing laser light off the surfaces, 3D scanners measure millions of points a second, accurate to a few millimeters to create a 3D data set,
or point cloud. Colors represent the intensity of reflection from the surface.
Individual data points are joined together via small triangles, connecting each of the dots and forming a wireframe. These triangles are used to form a solid surface from the points, which creates a solid 3D model. The 3D model generated from the point cloud is then colored using photographs taken of the surface of the structure.
The result is a photo-real 3D model which can be used to further study the monument and used for conservation and education.
