46 Tutorial 2: Working with Data
Planes Tab
The Plane tab enables you to:
• Select the Plane to modify
• Select the plane Offset in Z units
relative to the plane coordinates.
• Specify the Transparency of the
plane
• Indicate the name of the Relief grid
(if one is used for the selected
plane)
• Specify the Sample resolution of
the relief grid
• Specify the Base value of the relief
grid
• Specify the vertical Scale of the
relief grid
• Specify a minimum clipped value
for the relief grid
• Specify a maximum clipped value
for the relief grid
TO SELECT THE PLANE TO MODIFY:
1.
From the Plane dropdown menu select the plane to modify.
TO SELECT THE PLANE OFFSET IN Z UNITS:
1.
In the Offsets box, specify the offset value in ground units. Press the [Enter] key.
The plane will be redrawn in the 3D viewer with the new offset.
TO SPECIFY THE TRANSPARENCY OF THE PLANE:
1.
Move the Trans. Slider bar from left to right to increase the transparency.
Note: We use a “screen-door” dithering technique to make a plane transparent. This
method is fast and robust, but may not always give you what you expect
because the transparency screens will overlap in certain combinations. If you
only need to make one plane transparent transparency should work as you
expect. If you are displaying two planes and require both to be transparent,
you should set the transparency of each plane to 50%. If you want to make 3
or 4 planes transparent at the same time, set all planes to 25% transparency. In
the Sample box, specify the sample resolution.
TO SPECIFY THE RELIEF GRID SAMPLE RESOLUTION:
1.
In the Sample box, set a sampling resolution that is reasonable for the detail
required in the relief surface. Higher sample resolutions provide more relief
