9.5 Velocity Display

Once velocity picks have been made they can be gridded using the volume processing tools. The VMB plugins contains a special tree item that enables a quick application of the volume processing workflow without the need to process the entire volume:

Pressing "Add velocity display" in the right-click menu of a slice (inline, crossline, time-slice) adds a special layer. Its right-click menu does not allow the selection of stored volumes or attributes, but the selection of a stored volume processing (gridding) flow.

The selection of a flow will launch its computation on the current slice only. If you already added a velocity display ,you can either reload it in case of modification or select a different processing setup.

Although the display is for a single slice the computation is still volume-based. Therefore it can take some time to process and will make OpendTect unresponsive during that period of time. For large jobs batch processes may still be preferred.
