Release notes (kogeo 2.1): kogeo release 2.1 contains - alongside many bug fixes - a new data editing feature, ‘spectral decomposition’ and an improved handling of 3d data. Please update your old kogeo installation! When using kogeo 2.1, please replace all session-files of old kogeo versions - they’re outdated and won’t work anymore. Project databases created with previous versions of kogeo need to be changed manually in order to get them working with kogeo 2.1. For the moment, please mail me if you have questions about this. Release notes (kogeo 2.2): kogeo release 2.2 contains bug-fixes, but no new functions. An update from release 2.1 might help you if you have problems like these: misaligned slice displays and/or labels - misaligned volume rendering - strange behavior during neural network or attribute crossplot processing - wrong picks are deleted during horizon data import Release notes (kogeo 2.3): kogeo release 2.3 contains bug-fixes, but no new functions: Lots of details about picking horizons needed to be changed, I hope the things run more stable now. The ‘export horizon data’ function was a complete mess. There was a bug in the ‘export navigation’ function when working with 3d data. Release notes (kogeo 2.4): In kogeo release 2.4 the following things are new: - 2d horizon autopicker - revised crossplot classifier And a few bugs have been fixed, as well! Release notes (kogeo 2.5): If you encounter difficulties/crashes with this release, contact me, please. It’s most likely a problem with ‘OpenAL32.dll’ and might be fixed by changing it to another version. The main new thing in kogeo 2.5 is the completely revised 3d-viz. part featuring an oblique slice display for 3d data volumes. A database compaction function was added and a possibility to export trace header values into tables. Bugfixes include a more stable IBM-float import and problems with incorrectly interpreted trace delays of sub-millisecond-sampled data. Release notes (kogeo 2.6): This release of kogeo offers first of all an improved handling of line navigation. Coordinates are stored in double precision now, you can choose from more projection methods and use accurate 7-parameter transformations for datum shifts. The interaction of mouse movement and map views should work a lot better now. You can digitize and display arbitrary lines through 3d volumes. Objects to be displayed in a 3d view can be stored in a ‘3d object library’ to be independent from 2d windows. The data resampling function has been rewritten to do quadratic interpolation.
