Abstract

In this paper we cover direct rendering of volumes, which contain numerous similar instances of structures,
such as images of polycrystalline materials, fiber-reinforced polymers, or intracellular structures. In these
cases the density of the instances is so high, that the existing rendering methods provide no insight into the
volume due to the amount of occlusion between the instances. We propose a new visibility management
method for visualizing such data, allowing us to hide individual instances, highlight instances with specific
properties, sparsify the instances, and blend the segmentation with the raw data. We tested the method on
fiber-reinforced polymer data, where it allows for a better view of the volume interior.
