• Stereo Pairs—A toggle switch to enhance<br />

three dimensional effect by displaying a<br />

model with two slightly different<br />

orientations. It can also create orthogonal<br />

(simultaneous front and side) views. The<br />

degree of separation is set on the Stereo View<br />

tab of the Settings dialog box.<br />

• Perspective—A toggle switch to create a<br />

perspective rendering of the model by<br />

consistent scaling of bond lengths and atom<br />

sizes by depth. The degree of scaling is<br />

controlled by the Perspective “Field of View”<br />

slider on the Model Display tab of the<br />

Settings dialog box.<br />

• Depth Fading—A toggle switch to create a<br />

realistic depth effect, where more distant<br />

parts of the model fade into the background.<br />

The degree of fading is controlled by the<br />

Depth Fading “Field of View” slider on the<br />

Model Display tab of the Settings dialog box.<br />

• Model Axes—Displays or hides the Model<br />

axes.<br />

• View Axes—Displays or hides the view<br />

axes.<br />

NOTE: When both axes overlap and the Model axes<br />

are displayed, the View axes are not visible.<br />

• Background Color—Displays the<br />

Background color select toolbar. Dark<br />

backgrounds are best for viewing protein<br />

ribbon or cartoon displays. Selecting redblue<br />

or Chromatek 3D display will<br />

automatically override the background color<br />

to display the optimal black background.<br />

Background colors are not used when<br />

printing, except for Ribbon displays. When<br />

saving a model as a GIF file, the background<br />

will be transparent, if you have selected that<br />

option for Image Export in the Preferences<br />

dialog box.<br />

• Color By—Selects the model coloring<br />

scheme. See “Coloring Displays” on page 86<br />

for more information.<br />

• Toolbars—Click the name of a toolbar to<br />

select it for display. Click again to deselect. You<br />

can attach a toolbar to any side of the GUI by<br />

dragging it to where you want it attached. If<br />

you are using a floating toolbar, you can change<br />

its shape by dragging any of its edges.<br />

• Standard toolbar—Contains standard file,<br />

edit, and print tools. The commands are<br />

duplicated on the File and Edit menus.<br />

• Building toolbar—Contains the Select,<br />

Translate, Rotate, and Zoom tools in<br />

addition to the model building tools—<br />

bonds, text building tool, and eraser. These<br />

tools are not duplicated on any menu. This<br />

toolbar is divided into “safe” and “unsafe”<br />

tools. The four “safe” tools on the left<br />

control only the view – they do not affect<br />

the model in any way. This includes the new<br />

“safe” select tool and the new translate<br />

tool . The old select tool is now<br />

called the Move tool. Although it can also be<br />

used to select, it’s primary use is to move<br />

atoms and fragments.<br />

• Model Display toolbar—Contains tools to<br />

control the display of the model. These tools<br />

are duplicated on the View menu.<br />

• Surfaces toolbar—Contains tools to<br />

calculate and display a molecular surface.<br />

Molecular Surface displays provide<br />

information about entire molecules, as<br />

opposed to the atom and bond information<br />

provided by Structure displays.<br />

• Movies toolbar—Contains tools for the<br />

creation and playback of movies. Chem3D<br />

movies are animations of certain<br />

visualization operations, such as iterations<br />

from a computation. They can be viewed in<br />
