Volumetric data refers to three-dimensional datasets that represent objects, structures, or phenomena in a volume space, allowing for a comprehensive view of the data from multiple angles. This type of data is commonly used in fields like medical imaging, geospatial analysis, and scientific research. It enables professionals to analyze complex structures and visualize relationships within the data more effectively than traditional 2D datasets. The representation of volumetric data often requires advanced visualization techniques to interpret the insights accurately.
