The 1862 Gardner photo was then scanned into the computer and a wire-frame geometrical model was created. Importing the wire frame geometry of the Gardner photo into 3-D Builder, the common points between the 1862 and 1997 landscapes were established and an estimated camera focal length was entered to calculate the 1862 position of Alexander Gardner's camera. Using 3-D Studio Max, the 1862 Gardner photo was imported and used as a background. The newly created models from 3-D Builder were imported and the 3-D Studio Max camera was placed using the interpolated camera position supplied by 3-D Builder. The 3-D Builder software allowed the researchers to align the wire frame geometry of those portions of the 1997 buildings common to the 1862 Gardner photo. |
