In this menu display settings/styles can be changed.
In general, display styles are applied to the currently selected set of atoms and bonds.
By default, all atoms and bonds in a molecule are selected.
You may select individual atoms/bonds by using the selection cursor or by using script commands.
Atoms are not drawn, but are assumed to have the same radius that they would occupy. So bonds are drawn to the outer circumference of where the atom would be. Compare with *None*
This option can be useful when used in conjunction with atom labels to display atom type.
Atoms are labeled with their atom type. (What is the difference between Atom Type and Atom Symbol?)
This option may be checked if performance is unacceptable when manipulating large molecules. When this option is checked, wireframe rendering is used for displayed atoms and bonds during rotations, translations, and zoom operations. The molecule is rendered according to the current settings when the mouse is released.
This option controls rendering with perspective depth. When this option is unchecked molecules are rendered as an orthogonal flat projection onto the screen. When this option is checked, sizes and distances are adjusted for a camara perspective.
For a good example of this take a look at some of the crystal structures, such as samples/CdSe_nanocrystal.xyz or samples/HfO2_on_Si_relax.in
Alternatively, you can turn on the bounding box to see the effect of this setting (see below).
Displays cartesian axes with the origin at the center of the bounding box defined by the extreme coordinates of the molecule.
Note that the positive Y axis is at the top, unlike RasMol.
Displays the bounding box, defined by the extreme coordinates of the centers of the atoms in each of the three dimensions.
