GammaRay 3.2

Windows users: If you have not downloaded version 2.5.1 yet, please first download its ZIP (further down) and extract it into any directory as it contains all the required libraries to run version 3.2. Then download the 3.2 ZIP, which contains only the executable, and extract it to the same directory. The program manual can be downloaded by browsing the source tree, in the docs directory. Run the program by activating GammaRay.exe.

With this version:

🔵: Locmap points can be rendered without outlines (negative integers now allowed in options).
🔵: Cokriging: disabled warnings during LMC check to not clutter report.
🔵: Command line argument -no3d to disable the 3D Viewer. Some older graphics drivers or use in virtual machines crash with OpenGL 2. Uses in these situations can disable the 3D Viewer.
🔵: Command line argument -nolops to disable automatic project reloading. Sometimes a crash can corrupt the project, causing the program to crash upon rerunning the program, rendering it useless.
🔵: A message box pops up when a GSLib program outputs to stderr.
🔵: Memory usage monitor in the status bar.
🔵: 3D Viewer: Unvalued cells are not rendered in Cartesian grids.
🔵: 3D Viewer: Vertical scale. Useful for petroleum applications, where the vertical extent is usually much smaller than the areal extent.

Run the program by activating GammaRay.exe.

With this version:

🔴 : Orphan parameter widgets floating when reducing the count of parameter arrays.
🔴 : File paths with hyphens are no more allowed as they conflict with GSLib parameter syntax.
🔴 : Misbehaving when variables contains all-constant values.
🔴 : Invalid IJK clipping planes in the 3D viewer, which can cause crashes.
🔴 : Message box warning to the user of truncated Cartesian grid files, prompting her/him to take corrective measures.

LEGEND:
🔴 =Bug/Crash fixed.
