Abstract:

Valuable 3D graphical models, such as high-resolution digital scans of cultural heritage objects, may require protection to prevent piracy or misuse, while still allowing for interactive display and manipulation by a widespread audience. This article considers some techniques for protecting 3D graphics content, and describes a remote rendering system that we have developed for sharing archives of 3D models while protecting the 3D geometry from unauthorized extraction. Additionally, we demonstrate how digitized 3D models can be used to generate accurate physical replicas of artworks such as Michelangelo's David.
