polynomial texture mapping Herculaneum Project
A project of the Getty Conservation Institute
 

Innovative and non-invasive polynomial texture mapping was used to document the condition of the wall painting scenes in the Casa del Bicentenario. With this system, lighting can be changed over the surface of the painting to highlight flaking of the paint layers. Over time, this method can be used to monitor the condition of the wall paintings.
