 | PTM Image of the object |  
 |  | PTMs (Polynomial Texture Maps) dynamically display the way light illuminates objects. 
The information present in PTM images enables the PTM viewer to display the image using lighting models similar to those employed to illuminate virtual 3D-objects.  
These models allow different properties of the illumination experience such as light direction, color, reflectivity, and the sharpness of highlights to be displayed together or separately.  
The models also permit mathematical enhancement of illumination properties which can disclose surface characteristics impossible to capture with the naked eye or standard photography. 
Viewer allows you to display PTMs using your Java-enabled web browser.
