OpendTect Plugins - July19 Release

The July 2019 release of my free OpendTect plugins continues to focus on further enhancement to the Mistie plugin. There has also been an extension to the GeopackageExport plugin that displays lines and polygons from a Geopackage database on a 3D horizon.

As usual you can download binaries of the plugins for Windows and Linux from the documentation website:

Mistie Plugin - what's new?

The big news for the Mistie plugin is that 3D seismic data can now be included when estimating misties. The new Mistie Estimation dialog (accessed via the "New" icon on the Mistie Analysis window toolbar) now includes optional fields for specifying a 3D seismic volume and associated parameters:

The "2D Trace Step" is the trace interval, along the overlapping 2D lines, where the mistie estimation is performed. The mistie estimates for each overlapping 2D line segment are averaged. The resulting mistie estimates then appear in the Mistie Analysis window with the 3D data type/attribute prefixed by "3D_":

The 3D data can also be selected as the reference when computing the least squares corrections. Once saved these corrections can then be applied by creating 2D and 3D Mistie Application attributes that reference the saved correction file. Here is a video showing the whole process:

GeopackageExport Plugin

The plugin now adds a new feature to the "Add" context menu of 3D horizons in the scene tree called "Geopackage Display":

This allows GIS line and polyline data in a Geopackage Database to be draped over a 3D horizon. The user has control on the line color and width. Multiple layers can be displayed. Here is an example showing 2D lines and a 3D survey box outline:

Not sure if anyone will find this useful but I now know a lot more about adding stuff to the scene tree and drawing in the 3D scene.
