Using the Gather Picking Panel

The Gather Picking Panel allows you to pick any value, such as an anisotropic parameter. Here, you can define your input volumes and assign each one a discrete value.

At each location, the picker will show you the displays from each of those volumes, and you can pick which one you like best at a given time/depth.

Using the picks generated in this panel, the Picked Function Model will then convert them into a single 3D volume with the picked values smoothly interpolated (see Picked Function Model).

Available in: Image Gather Processing module

Gather picking settings

Gather picking settings
  1. From the View menu in the Control Panel, select Gather Picking Panel.
  2. In the Settings tab of the panel, click the Add icon at Volume to select your input volumes.
  3. If you wish to use gather volumes, select the type (i.e. offset, velocity) and define the extents of the gather to display in the panel at Gather.
  4. At First value, type a discrete value to assign to your first volume, and the Increment at which the values will be assigned to subsequent volumes.
  5. You can change the order of the volumes by clicking to the left of the volume and dragging it up or down.
