Enhancing Transparent Visualization of Cultural Heritage Point Clouds through Adaptive Opacity Control

A novel method of adaptive opacity control for region highlighting, which interprets shading as a distribution of opacity, is introduced, which enables selective highlighting of user-specified regions, enhances the visibility of complex structures, while also allowing interactive dynamic shading by continuously changin...
