Digitizing Three Dimensions
The 3DRAW PRO 3D digitizer from Polhemus used a pen to touch the object's surface. This device recorded the x, y and z coordinates of the tip position in 3-dimensional space and output them directly into popular CAD and graphics programs. (Image courtesy of Polhemus, Inc.)
