Shaded Preview
Shaded preview displays an object preview, complete with textures, and
transparency.

Depth Cue
The Depth Cue option draws wireframes which fade to the Background
as the distance from the Camera
approaches the Outer Radius.
Inner Radius
Distance from the Camera where wireframes
begin to fade.
Outer Radius
Distance from the Camera where wireframes
are 100% Background.
Background
Every view has a background color. Clicking in the box to the right
of the Background title will open
the Apple color picker, allowing
you to set the background color.
Image
Any view can also have a PICT image as a background. This is helpful
when modeling something from a scanned image (i.e. take photos of an
object from the top, front and right) or for placing a computer model
into a real scene. PICT sequences can also be used for rotoscoping.
Click on the box to the right of the Image check box to open the Texture
Manager dialog. See the ShaderMaker
section for more details.
Visible Grid
When checked, this option shows this viewing panes grid. When unchecked,
the grid will be hidden.
