摘要：
Computationally efficient encryption techniques for polygonal mesh data are proposed which exploit the prioritization of data in progressive meshes. Significant reduction of computational demand can be achieved as compared to full encryption, but it turns out that different techniques are required to support both privacy-focussed applications and try-and-buy scenarios.
