An Interactive 3D Visualization Tool for Large Scale Data Sets for Quantitative Atom Probe Tomography

摘要

Several visualization schemes have been developed for imaging materials atthe atomic level through atom probe tomography. The main shortcoming of thesetools is their inability to parallel process data using multi-core computingunits to tackle the problem of larger data sets. This critically handicaps theability to make a quantitative interpretation of spatial correlations inchemical composition, since a significant amount of the data is missed duringsubsequent analysis. In addition, since these visualization tools are notopen-source software there is always a problem with developing a commonlanguage for the interpretation of data. In this contribution we presentresults of our work on using an open-source advanced interactive visualizationsoftware tool, which overcomes the difficulty of visualizing larger data setsby supporting parallel rendering on a graphical user interface or script userinterface and permits quantitative analysis of atom probe tomography data inreal time. This advancement allows materials scientists a codesign approach tomaking, measuring and modeling new and nanostructured materials by providing adirect feedback to the fabrication and designing of samples in real time.
