The Display Settings

The display settings dialog is accessible through the Main Menu, then "Options", then "Display Settings" entry :




It is made of nine tabs, and each tab allows to configure the display appearance of a category of items :
1 - Atom and bonds style
2 - Atom colors
3 - Lights position and colors
4 - Critical points and bonds paths
5 - Various stuff like background color, atomic axis system arrows etc...
6 - Atom and critical points labels
7 - Constrains on electron density



1 - The first tab is used to change globally the atom drawing style (lines or ball and sticks) and to configure the lines width or the balls and stick sizes and resolution. The probability and principal axis appearance and colors of thermal displacement ellipsoids can also be changed from this tab :





2 - The second tab allows to change the color attributed to every chemical specy, including special ones as "dummy atoms", "virtual atoms". It allows also to globally configure atom colors using B factors for instance.





3 - The third tab is used to modify the position and color of the main light source, and to add a second one if needed. The reflectivity property of material can also be changed from this tab. To see the effects of lights modification one must be sure a corresponding material is displayed, as ball and stick mode or a 3D isosurface.





4 - The fourth tab gives options to modify the appearance or visibility of critical points, bond paths and curvatures. It change globally all critical points by categories (3,-1), (3,+1) etc...  The CP size parameter is only active when the critical points are displayed in "ball and stick" mode.





 5 - The fifth tab corresponds to various parameters. It change the background, measurments (distances ...), selections marks and various tools colors. Also the definition and orthogonal atomic axis systems arrows colors and the "fog" color. This latter by defaults is synchronized with the background color.





6 - The sixth tab allows to configure viewer text, such as atomic and critical points labels font, composition and color, and measurments font and color. Composition means that an atomic label can be made of any combination of parameters, separated by "-", "_" or a blank character. Example : CB_3-0.5 is composed of atom name, "_", fragment number, "-" and occupancy.
 





7 - The seventh tab is used to change the way valence, multipolar or kappa constrains are displayed on the viewer. For the moment three methods can be used : by colored spheres or toruses so that one constraint scheme corresponds to one given color, with the reference atom highlighted. The third method is based on using two colors scheme, the reference atom being surrounded by a red sphere, and the constrained atoms by a green sphere.
