Example 1: Use groups to display data from multiple 3D and 2D volumes
Arblines can span 3D and 2D line segments, through several surveys. A group of volumes will show data from many different datasets and surveys along these arblines.
A group can be created to view multiple 3D and 2D lines/volumes along one arbline. See Viewing Multiple 2D Volumes.
Example 2: Using groups to co-render volumes
Groups allow for multiple volumes to be displayed in a map or section view, allowing characteristics captured by different attributes to be easily visualized.
Use this to "merge" amplitude and velocity data in the same view, or viewing multiple seismic attributes simultaneously. The example Groups - Combining Volumes for Visualization shows how incoherence and curvature volumes can be grouped to display structural features.
