Backgrounds
Specifies that backgrounds will be displayed in 3D views while navigating
and editing.
Configure: Textures
Enter mode [ON/OFF] <ON>: Specify whether you want textures turned on or off
Configure: Transparency
Enter mode [Low/Medium/High] <Low>: Select a transparency level
If Materials is turned on, you can also configure textures and transparency.
Enable Textures
In 3D views, shows textures attached to objects using the RMAT and SETUV
commands. Materials must also be turned on for textures to be visible.
Transparency
Adjusts the transparency quality to improve image quality, but at the
expense of redraw time. At the low-quality setting, a screen-door effect
achieves transparency without sacrificing speed. At the medium-quality
setting, blending improves image quality. At the high-quality setting,
blending and extra processing produce an image free of visual artifacts, but
at the cost of drawing speed. Materials must also be turned on for
transparency to be visible.
Geometry
Determines how to display isolines in 3D and whether to display back faces
in 3D.
Configure: Geometry
Enter option [Isolines on top/Discard backfaces] <Isolines on top>: Specify an
option to configure
Configure: Isolines on top
Enter mode [ON/OFF] <ON>: Specify whether you want isolines on top
Configure: Discard backfaces
Enter mode [ON/OFF] <ON>: Specify whether you want back faces to be discarded
Isolines on Top
Displays isolines for front and back faces in all shade modes except Hidden.
Isolines for the back faces are displayed on top of the shading for the objects
in 3D. Turning this option off hides the isolines for the back faces.
Discard Back Faces
Discards back faces when drawing objects. You cannot see the effect of
discarding back faces on some objects, such as spheres, because you cannot
