Color Enhancement Techniques for Rapid Prototyping

Paolo Cignoni, Enrico Gobbetti, Ruggero Pintus, and Roberto Scopigno

December 2008

Abstract

We propose to exploit the color capabilities of recent rapid pototyping hardware devices to enhance the visual appearance of reproduced objects. In particular, by carefully pre-computing surface shading, we are able to counterbalance the sub-surface scattering (SSS) effects that hinder the perception of fine surface details. As a practical result, we are able to reproduce small scale copies of cultural heritage artifacts with an increased readability of the tiniest features and particulars, without requiring manual post-reproduction interventions or hand painting.
