Log Ribbon Tab

Context-sensitive tab — appears when the 3D Logs context is active.

Commands available on the Log ribbon tab, grouped by panel.

Edit​

Set Dip Domain​

Tooltip: Set the dip domain of the selected units

Set a dip and dip azimuth on the log units selected in the 2D log panel, so their thicknesses are corrected to true stratigraphic thickness. Greyed out until at least one unit is selected.

Extract Image Track​

Tooltip: Extract a rectified image strip along the log path

Sample the outcrop's texture along the log's path and flatten it into a straight, depth-registered strip — the outcrop equivalent of a borehole image log. VRGS finds the outcrop itself: the mesh the log is attached to, then the active mesh if it is shown and textured, then the nearest shown, textured mesh the path crosses. You are asked for the image width across the log in metres, 1 m to start and then the last width used; the strip is written as a JPEG into the project's LogImages folder and added to the log, aligned to the depths it was taken from.

The path used is the detailed tracked deviation where the log has one, otherwise its unit-boundary deviation.

Needs a textured mesh and a digitised path

"No textured mesh is visible along this log's path" or "The active log has no path to extract along" mean exactly what they say — show and texture the outcrop, or digitise the log path first.

Geodesic Path​

Tooltip: Follow surface geodesics when tracking a log

A toggle that changes how the path between two log markers is tracked. On, the path is straightened onto the shortest on-surface (geodesic) route. Off, it is restricted to the mesh's own edges, which follows the triangulation rather than the surface.

Edit Deviation​

Tooltip: Move deviation nodes

Click and drag the nodes of the log's deviation path in the 3D view to correct its route.

Tooltip: Link a log unit

Link a log unit to an interpretation object in the scene.

Extend Deviation​

Tooltip: Extend the deviation path

Continue the log's deviation path from its current end by digitising further points.

Defaults​

These set what a new unit on the active log starts as; they do not change units that already exist.

Grain Size​

The default grain size for new log units.

Carbonate​

The default carbonate classification for new log units.

Facies​

The default facies for new log units.
