Depth Fading3D enhancement:<br />

The depth fading feature in Chem3D creates a<br />

realistic depth effect, by making parts of the model<br />

further from the viewer fade into the background.<br />

Depth shading is activated by selecting the Depth<br />

Fading checkbox on the Stereo and Depth tab of the<br />

Model Settings dialog box, by selecting Depth<br />

Fading from the Model Display submenu of the<br />

View menu, or by clicking the Depth fading icon<br />

on the Toolbar.<br />

Perspective Rendering<br />

Chem3D supports true perspective rendering of<br />

models. This results in a more realistic depiction of<br />

the model, with bond lengths and atom sizes<br />

further from the viewer being scaled consistently.<br />

The “field of view” slider adjusts the perspective<br />

effect. Moving the slider to the right increases the<br />

effect.<br />

Coloring the Background<br />

Window<br />

Chem3D allows you to select a color for the<br />

background of your models. A black or dark blue<br />

background can be particularly striking for ribbon<br />

displays intended for full color viewing, whereas a<br />

light background is more suitable for print copy.<br />

To change the default background color of the<br />

model window:<br />

1. In the Colors and Fonts tab of the Model<br />

Settings control panel, click Background Color.<br />

Background<br />

color<br />

Depth Fading,<br />

Perspective, &<br />

field of view slider<br />

The Color dialog box appears.<br />

2. Select a color and click OK.<br />

NOTE: The background colors are not saved in PostScript<br />

files or used when printing, except when you use the Ribbons<br />

display.<br />

CAUTION<br />

Moving the slider all the way to the left may make the<br />

model disappear completely.<br />

Coloring Individual Atoms<br />

You can mark atoms individually using the Select<br />

Color command in the Model Explorer.<br />
