Skyscraper visualization of multiple time-dependent scalar fields on surfaces

Vessel Maps: A Survey of Map‐Like Visualizations of the Cardiovascular System

“…To enable a simultaneous exploration of more than two scalar fields, Meuschke et al [MVG * 21] introduced an aneurysm map combined with a glyph‐based depiction of the corresponding scalar values, called “Skyline visualization”, see Figure 8. Since the size of conspicuous wall regions on the map should be preserved, the area‐preserving parameterization ARAP was chosen.…”

“…On the aneurysm map, 3D bar charts are generated, where the color‐coding of the floors encodes different scalar values. Image from [MVG * 21].…”

“…Meuschke et al generated aneurysm maps with different parametrization techniques to support the visual analysis of multiple scalar fields simultaneously [MVB * 17, MVPL18, MGB * 19, MVG * 21]. Since only the aneurysm without adjacent vessels is to be mapped, the aneurysm has to be separated from the healthy vessel part first.…”

“…The cardiovascular system is, after all, a spatio‐temporal domain that is highly dependent on the cardiac cycle. The possibility of using vessel maps for, e.g., temporal navigation tasks, has only been adopted in very few works [EEL * 19, MVG * 21, ZTWW21]. Not only blood flow information is temporally resolved, but parts of the cardiovascular system, namely the heart and larger arteries, are also constantly in pulsating motion.…”

Special C&G session at EuroVis 2022

“…First, Meuschke et al [2] presented a system that creates a visual representation on a 3D surface of several time-dependent scalar fields. This allows practitioners to understand the change in such data with respect to the 3D surfaces to which they correspond.…”
