StrViewer is a graphical viewer and post processing tool use to view 3D spacial arrangement of the atoms grown through EpiGrow simulator. StrViewer can accomodate millions of atoms in a single frame. Depending upon Hardware graphical capacity over which it is running, it can accomodate more than billions of atoms simulataneously for visualization. It is capable to read the atomic configuration files with no limitations. StrViewer is powerful tool to extract the lattice constant, defect densities and strain with in the grown sample from TNL-EpiGrow simulator. The extraction feature of StrViewer is the state of art feature as these informations can not be extracted with any kind of sophisiticated scientific instruments.
