Opacity volume based halo generation and depth-dependent halos
2012
The Visual Computer
Preserved Fulltext
Halos are generally used to enhance depth perception and display spatial relationships in illustrative visualization. ...
At the preprocessing stage, we generate, on graphics hardware, a viewindependent halo intensity volume, which contains all of the potential halos around the boundaries of features, based on the opacity ...
