In VIVID-CELL: Cell visualization of unified microscopic data and procedurally generated sub-cellular structures, we want to use real biomedical volumetric microscopy data in the development of visual models of subcellular structures: cytosol, mitochondria, compartments of the lysosomal pathway, Golgi apparatus and fusiform vesicles. We want the developed visual models to reflect the visual properties of these structures in the real data so that they can be used in the procedural generation of numerous entities of individual structures within the given cell boundaries. Furthermore, we want to develop visualization methods that will support using the developed visual models and their adaptation and fusion with the rendering of real microscopy data. The developed models and methods will be compared with state-of-the-art visualization methods and evaluated in a user study, where we will determine the meaningfulness and correctness of the visualization outputs. We believe the results will be useful in biomedical research, especially for confirming the distribution of structures within the cell, the variance of their shapes, and their involvement in cellular processes.
