Change here the visual representation for a single bond or a list of bonds.
<p/>
To modify a bond, click over its graphic image, or write its id on
the <b>Bond</b> entry. To modify a list of bonds, press the button
<b>List</b> (after creating the list of bonds with <b>Bond->Select</b>).
Parameters for empty entries or <b>Local</b> choices remain unchanged.
<p/>
To change a bond name write the new name in the <b>Bond</b> entry,
followed by the bond number (GAMGI needs the number to identify the bond).
To change the name for a list of bonds, press <b>List</b> first
and then write the new common name in the <b>Name</b> entry.
<h3>Style</h3>
The <b>Style</b> option menu controls the bond visual representation:
cylinders in <b>Solid</b> mode, simple lines in <b>Wired</b> mode.
<p/>
The cylinder gives a high visual quality, when coupled with lights and
perhaps a perspective projection. A cylinder uses considerable screen
space though and is time consuming.
<p/>
Wired objects do not have a 3D representation, so diffuse and
specular lights are not reflected, becoming poorly invisible when using
lights, unless the ambient component is important.
<h3>Size</h3>
In <b>Solid</b> mode, this parameter controls the size of the bond
cylinders. Combining bond <b>Size</b> with atom <b>Variancy</b>
and <b>Size</b>, it is possible to obtain a wide range of styles
to represent atomic structures.
<p/>
An elegant style is to represent bonds with the same <b>Size</b>
as atoms (<b>0.5</b>).
To guarantee that bond cylinders are closed by atom spheres,
bond <b>Size</b> should not be larger than atom <b>Size</b>.
<h3>Color</h3>
The <b>Color</b> button controls whether the bond is represented with
its own, independent color, or inherits the colors of the parent atoms.
By default colors are inherited.
<h3>R, G, B</h3>
Change the bond color, from black (0.0, 0.0, 0.0) to white (1.0, 1.0, 1.0),
when the bond is rendered with its own, independent, color.
<h3>Scale</h3>
Change the bond size, including its child objects. Bond objects are
scaled around the bond line. The visual representation of an object
is always scaled by its own scale factor multiplied by the scale factor
of all its parent objects until layer, inclusive.
<p/>
Line widths in GAMGI are not affected by <b>Scale</b> attributes, so
bonds represented in <b>Wired</b> mode remain unchanged by <b>Scale</b>
(but not its child).
