1. predefine some default view and enable comprehensive analysis work 1. predefine some default view and enable comprehensive analysis work
flows for the user flows for the user (Fig 1).
- you can save and load views (screen shot 01). - save and load views.
- you can use different graphic representations - points, bonds, `VDW' - use different graphic representations - points, bonds, `VDW'
- atoms as spheres, etc. (screenshots 02 and 03). - atoms as spheres
I did not find volume rendering like in Visit but the spheres may by
opaque or transparent which gives a volumetric impression.
2. basic user interaction: 2. basic user interaction:
a) start, pause, continue time evolution a) start, pause, continue time evolution
- you can load different molecules and switch between them (screenshots - load different molecules and switch between them (screenshots
04 and 05). I did not find any "player" functionality like in VisIt or 04 and 05).
I just cannot use it correctly maybe. - no default "player" functionality like in VisIt or ParaView
b) rotate, transfer, zoom in or out, change the number of shown unit b) rotate, transfer, zoom in or out, change the number of shown unit
cells cells
- all works - you can even leave the model rotating by itself - exept - all works
"change the number of shown unit cells" - this I did not find
c) determine species type and atom number by clicking the sphere c) determine species type and atom number by clicking the sphere
representing that atom representing that atom
- you can do various types of analysis (screenshots 06, 07 and 08) but - types of analysis (Figs 2,3,4) but from the menu and not by simply clicking on the atom. The window is not
from the menu and not by clicking on the atom. The window is not
interactive. interactive.
d) change the iso-value for the density, colour scale for the d) change the iso-value for the density, colour scale for the
volumetric data volumetric data
- you can do changes in graphical representation like coloring method, - not yet identified
surface opacity, resolution, etc. (screenshots 09, 10 and 11).
3. select a plane and display a colour map or a contour plot of the
(interpolated) volumetric data
- you can do a clipping plane (screenshot 12) but I did not find any
contour plots.
4. calculate the density integral within a 3D box selection 4. calculate the density integral within a 3D box selection
- did not find - not yet identified
5. display distances, angles, and dihedral angles by selecting atoms 5. display distances, angles, and dihedral angles by selecting atoms
- I think it is not possible - not yet identified
6. interactively replicate the unit cell 6. interactively replicate the unit cell
- did not find. - not yet identified
