What's new:
🆕 Markov Chains Random Field Simulation (manual Section 14.3).
🆕 New data type: Segment Set (manual Section 5.3.3).
🆕 Convert facies names/symbols into facies code in data files (manual Section 7.9).
🆕 Convert variable to categorical variable quickly and directly (no classification step) (manual Section 7.10).
🆕 New object: Facies Transition Matrix (manual Section 11.1).
🆕 Cyclicity analysis and significance test (null hypothesis) for Markovian memory (manual Section 11.1.2).
🆕 Facies transition diagram (manual Section 11.1.3).
🆕 Experimental transiogram calculation and transiogram modeling dialog (manual Section 11.2).
🆕 Constructor of GeoGrids from multiple horizons (manual Section 15.2.2).
🆕 Multiple Facies Relationship Diagrams for a range of separations (h) (manual Section 11.2.2).
🆕 Flip grid data in either U, V or W directions (manual Section 7.13).
🔵 Can display 2D grids as surfaces (z = variable).
🔵 Categories can have a custom RGB color, in addition to the mandatory GSLib color.
🔵 Antialiased PostScript (plots) rendering.
🔵 Viewer 3D: option to display attributes in GeoGrids in UVW Cartesian grid.
🔵 Making continuous variables as categorical now avaliable for Cartesian and GeoGrid grids.
🔵 Added color scale setting for Attributes in 3D Cartesian and Geo- grids.
🔵 Minor performance improvement for the spatial index.
🔵 Improved performance of spatial index bulk loading.
🔵 Factorial Kriging: choice of search algorithm: one good on average for most data sets; another tuned for large datasets.
🔵 Added Cartesian grid-to-Cartesian grid collocated values transfer.
🔵 Added Cartesian grid-to-Point set collocated values transfer.
🔶 Cateorical definitons now can have tens of classes.
🔶 Hability to save plots not originated from GSLib programs.
🔶 File::readFromFS() was not overidden in DataFile.
🔶 CartesianGrid's IJKtoXYZ() was not returning the centers of the cells per GridFile's contract.
🔶 Viewer 3D: rendition of 3D Cartesian grids with incorrect cell dimensions.
🔶 Viewer 3D: categorical variables are rendered with the colors of its categorical definition.
🔶 Categorization of variables where incorrectly mapping NDVs to fallback category code.
🔶 3D Viewer: unnecessary ::New() within a loop causing major bottleneck in surface visualization.
🔶 GeoGrid was not implementing freeLoadedData().
🔶 Added a defensive assert to DataFile::getCategoryDefinition().
🔶 Negative size values for files larger than 2GB.
🔶 Incorrect greater-than operator in comparator for a multiset, resulting in inverted sorting.
🔶 SVDFactor::get[Min/Max]Value(): replaced std::[min/max]_element() calls with explicit loops since these functions don't ignore NaNs.
🔴 Category Definition editor: Crash caused by passing invalid GSLib color codes to Util::getGSLibColor().
LEGEND:
🆕: NEW FEATURE; 🔵: enhancement; 🔶: defect fix; 🔴: bug fix.
