Grouping geo-bodies in the Data manager

Geo-bodies extracted from a seismic volume with Extract geobodies... - see Seismic 3D - are collected in a subfolder of Geo-bodies named after that volume, so it is always clear which volume a body came from. Bodies extracted later from the same volume are added to the folder that already exists, and each further volume gets its own folder.

This layout is controlled by Group by source volume in the context menu of the Geo-bodies folder, which is selected by default. Clear it to list all geo-bodies directly under Geo-bodies.

Group by source volume and Group by class are alternatives: selecting one clears the other, so the branch is grouped either by source volume or by class, never by both. The mode in use is stored with the project.

Geo-bodies that have no source volume stay directly under Geo-bodies even while Group by source volume is selected. This applies to bodies loaded from a file, bodies produced by the Create 3D geological model wizard, and bodies in projects that were saved before the source volume was recorded.

Creating a 3D geological model

Geo-bodies are built with the Create 3D geological model wizard, launched from the Geo-body group of the Reservoir ribbon tab. On its General tab you define the model layers (Name, Top, Bottom, Age) and the bounding polygon, and on the Faults tab you choose which faults cut the model.

Fault models

On the Faults tab, in addition to selecting individual faults you can enable whole fault models under Fault models. Only depth-domain fault models are listed. When a fault model is checked, its fitted fault surfaces are used to cut the geological model together with any individually selected faults.

Displaying a geo-body in the 3D view

Click a geo-body in the 3D view to select it, then click the settings (gear) button in the top-right corner of the view to open the Geomage 3D Settings window. Its Inspector tab shows the properties of the selected object, including a Display Mode list that sets how the body is drawn:

• Solid - the default: the body is drawn as filled surfaces.
• Transparent - the body is drawn filled but rendered so that objects behind it stay visible when Opacity is set below 1.
• Outline - only the edges of the body are drawn.
• Points/Voxels - only the nodes of the body are drawn.
• Surface Mesh - the edges and the nodes are drawn together.

Extracting points from a geo-body

To turn the geometry of a single geo-body into point data, right-click that geo-body in the Data manager and choose Extract points. The nodes of its surfaces are collected, repeated coordinates are dropped, and the result is stored as a new object under Points, where it behaves like any other point set.

The new point set takes the name of the source geo-body with the suffix _points - a geo-body named Geobody_1 gives Geobody_1_points. If that name is already in use, a number is appended (Geobody_1_points 1, Geobody_1_points 2, and so on), so an earlier extraction is never overwritten.

Besides the X and Y coordinates, the set carries a Depth attribute holding the Z value of each node. That attribute is already assigned the depth role, so the extracted points appear at the correct depth on sections and in 3D without further setup.
