4.12. 2D Seismic

The user can either add 2D seismic lines or create new ones from 3D data.

Right click on 2D and select Add to add a 2D line set. After pressing Select, you must select which lines from the available lines you wish to display. You can always add or remove lines later.

The pop-up menu of the line set has these options:

Add line(s): Here you select what lines available in the current line set you want to add to the display list.
Select Attribute: Here you select what attribute you want to display on all lines currently loaded from the line set.
Show all: Switches on all currently loaded line names or the lines themselves from the line set.
Hide all: The opposite of Show all: it switches off all currently loaded line names or the lines themselves from the line set.
Remove: Removes the entire line set from the tree.

The popup menu from the individual lines from the line set has these options:

Select attribute: To set the attribute loaded onto this individual line. Remember that volume attributes can not be loaded on 2D lines. You need to define attribute(s) specifically for the 2D line set.
Properties: The Properties option refers to display parameters such as transparency and ambience.
Resolution: Allows changing the graphical resolution of the element. The default does not involve any rescaling before the data is sent to the graphics card. Moderate and high do some pre-interpolation before the data is sent to the graphics card and generally results in a clearer picture. If the memory of your graphics card does not allow high resolution the element becomes black.

Lock / Unlock: Locks the selected object. This prevents accidental removing, moving, or displaying data on the object. After clicking unlock all manipulations are possible again.
Duplicate: Duplicates the line as an empty element in the tree. On the new element, you can display a different attribute while keeping the original data directly available too.
Show/Hide linename: Shows or hides the name of the line in the graphical area.
Position: Pops up a new window where the visual data range of the current line can be set.
Remove: Removes the line from the line set and the tree.

Moreover, you can change and display attributes of a 2D line set from tree. Right-click on the line set in the tree. You will see the options shown in figure below.

Set Z Range: Specify the Z-range of line set to be displayed
Add Attribute: Adds the same attribute display to all lines within the line set.
Edit Attribute: Edits or changes the attribute of all lines within the line set.

Remove Attribute: Removes the attribute from lines.
Edit Color Settings: Applies the same color settings for all lines in a line set.
