Visualization of Time-Varying Volumetric Data using Differential Time-Histogram Table
We introduce a novel data structure called Differential Time-Histogram Table (DTHT) for visualization of timevarying scalar data. This data structure only stores voxels that are changing between time-steps or during transfer function updates. It allows ef�cient updates of data necessary for rendering during a sequence of queries common during data exploration and visualization. The table is used to update the values held in memory so that ef�cient visualization is supported while guaranteeing that the scalar �eld visualized is within a given error tolerance of the scalar �eld sampled. Our data structure allows updates of time-steps in the order of tens of frames per second for volumes of sizes of 4.5GB, enabling real-time time-sliders.
