%description
Tomviz is a cross-platform, open-source application (SCI/Kitware/OpenChemistry)
for the processing, visualization and analysis of 3D tomographic data, widely
used in materials science and electron microscopy. It provides a ParaView-based
pipeline GUI with a Python operator framework for reconstruction, segmentation
and quantification of volumetric datasets.
