Multi-valued volumetric visualization
Thomas A. Foley, David A. Lane · IEEE Visualization · 1991
Effective methods for visualizing several sets of volumetric data simultaneously are presented which involve the composition of multiple volumetric rendering techniques. Although there are many methods for visualizing volumetric data, most of these methods can only render one set of volumetric data at a time. By rendering several volumetric data sets simultaneously, relationships among the data sets can be visualized, which may be difficult or impossible to visualize when the data sets are rendered individually.
