Introduction
Due to the increasing computer power and memory sizes the computed data sets become more complex. In order to comprehend them an efficient visualization becomes necessary. While most of the available visualization tools provide merely the visualization, the interaction with the data is often ignored. In the PHInaX project [1] we focus on the development of render techniques which allow the implementation of smart interactors depending on the physical context. PHInaX has full access to all physical algorithms implemented in S/PHI/nX [2] and can incorporate them directly into the graphics render pipeline.
Atomic Structure Visualization
New render techniques to visualize up to 1.000.000 atoms interactively on standard PC hardware has been developed and implemented into the visualization module of PHInaX. It allows high quality rendering of complex structures. Only with this high render performance interaction becomes possible.
Interactors
In the visualization module of PHInaX we have developed new interactive elements (gizmos) for modifying atomic structures. The module is based on the S/PHI/nX library and has therefore full access to all physical and numerical algorithms provided by that library.
In Fig. 1 a screenshot of an interactive PHInaX session is presented by means of a cubic Fe24Mn8C fcc supercell to model Mn-rich austenitic steels.
