When a model is brought into the Superview IV Results environment, it is displayed with the "Shaded with Mesh" option active by default. You can change the location of the light source that is used for shading by doing the following:

• Use the "Tools:Options..." command sequence to access the "Options" dialog. On the "Graphics" tab, under "Lighting", click on the "Setup..." button as shown in Figure 1. The "Lighting Setup" dialog will appear.

• Under "Lighting preview", use the horizontal and vertical sliders to specify the light source location as shown in Figure 2.

Additionally, the "Lighting Setup" dialog enables you to specify other lighting options including:

• The "Enable light" checkbox toggles lighting on or off.
• Clicking on the colored button under "Lighting preview" accesses the "Light Color" dialog, which lets you specify the color of the light.
• The pull-down bar beneath the preview window lets you specify up to four different light sources.
• Clicking on the colored button under "Ambience" lets you specify the color of ambient light.
• Under "Preview model", the "Colored", "Uncolored" and "Textured" options can be used to modify the display of the model under "Lighting preview".
• Clicking on the "Reset" button restores the default settings for this dialog.
• The "OK" button is used to accept changes. The "Cancel" button is used to close the dialog without making changes.
