The 3D View Settings screen is used to configure the information
displayed in the 3D View screen.
; Height Exaggerated to the Maximum : When
checked, the height exaggeration is automatically set to
a high value. When unchecked, the height exaggeration
can be set manually in the next field.
Height Exaggeration Ratio: is the value that the height
is multiplied by in the 3D view. Higher values mean
more exaggeration; a value of 1.0 would result in no
exaggeration.
; Hidden-line Removal : When checked, will hide all the
lines that occur behind other surfaces in the 3D View. The
image shown here is identical to the image shown on Page R-
83 except the hidden lines are not removed.
; Display the Difference : This applies only to DTM
stakeout. When checked, the vertical portion (z-axis) of the
3D View screen is computed by the elevation differences
between the non-reference DTM surface and the reference
DTM surface. This will result in any objects that occur
above or below the reference DTM to clearly stand out as
hills and valleys and the volume information provided in the 3D View
screen will be between the staked points and the reference DTM.
When unchecked, the Datum field can be set to a reference elevation.
Cut and fill volumes in the 3D View screen will then be based on the
difference of a horizontal plane at the elevation specified here and the
non-reference DTM surface.
