Each slice is manually extracted from a photo by clicking along the edge of each slice using program cordinates2.pl.
The 2d representations are represented as Scalar Vector Graphics files which can be displayed in any web browser. The 2d representations are used to scale and transform the slices so that the align with the cordinates axes and have matching sizes using createSlices.pl.
These slices can then be loaded into FreeCad to position them to construct the 3d representation of the dog.
