Transmission Electron Microscope +
Atom Probe Visualization

By visualizing data sets from different imaging techniques in a fully immersive environment, experimentalists can quickly gain insight into the spatial and compositional characteristics of microstructural features in materials. This dataset is a combination of transmission electron and atom probe tomograms which show a 1:1 association between Helium bubbles and oxide nanoclusters. Understanding this association is needed to design better materials for advanced nuclear reactors.

The TEM+AP visualization was built for the AlloSphere and features navigation via PhaseSpace motion capture gloves and a touchpad UI. I worked on graphics and rendering including implementing an order-independent transparency algorithm, optimizing isosurface representations, lighting and shading, and omni billboarding for text labels.
