4. Scene Functions
This chapter will describe the methods for changing the way the model's surrounding scene looks in quick3D. When a quick3D scene format file is saved, these scene settings will get captured in it. Below are descriptions of each of the scene menu items.

4.1 - Background (menu items: Background Color, Background Texture)

A solid color or a texture from an image file may be specified for the scene background. Selecting the Background Color menu item displays the standard color palette dialog box. Selecting Background Texture displays the dialog illustrated in Figure 4.1.

Background image parameters dialog window

Select the desired image file for the background by clicking the Choose Image File button. You can control the overall quality of the texture by using the Texture Quality slider. If the Enable Background Image checkbox is selected then the texture will override the background color, otherwise the texture will not be visible.

4.2 - Depth Cueing (menu items: Depth Cueing, Depth Cueing Color)

Depth cueing is an alternative method to lighting for adding the appearance of depth to the scene. Depth cueing, however, looks more like fog than light. Using the Depth Cueing sub-menu, it can be turned off or set to a value within the range of 10% to 99% (100% would mean total obscuration of the model). The color of the cue can be changed using the Depth Cueing Color menu option.

4.3 - Gamma Correction (menu items: Gamma Correction)

Variations in video hardware, device drivers, and related items can cause the overall brightness level to be at an undesirable level. To adjust the gamma level, select Gamma Correction from the menu and the dialog displayed in Figure 4.2 will appear. Use this dialog to set the desired gamma level.
