Due to the end of Oracle Java free release updates, the IDV project has officially moved from Oracle JDK to OpenJDK packages that receives support via the community. The AdoptOpenJDK provides prebuilt binaries from OpenJDK class libraries. All AdoptOpenJDK binaries and scripts are open source licensed and available for free. The version of the AdoptOpenJDK distributed with the IDV is 1.8.0_282. See the adoptOpenJDK Library for a more details information.
The version of the netCDF-Java library currently distributed with the IDV is the 5.4.2. See the netCDF-Java Library for a more details information.
Java Webstart, Windows app and MacOS certificates have been renewed and will be valid until at least May 30, 2020 (MacOS certificate is valid until 2024). Moreover, as properly signing the IDV under these different environments can be an involved process, this information has thoroughly documented here. The IDV MacOS installer in this release has been notarized by Apple in order to run by default on MacOS.
The cross boundary subset in the grid coverage type works similar to the grid file subset where you can set the property for subset all fields in the Data Source Property panel or you can override the default setting for a particular field in the field selector subset panel. The only difference in the Coverage data spatial subset is that it will allow users to flip longitudes in a cyclic rect linear grid from 0/360 to -180/180 (or vice-versa) before performing the cross boundary subset.
New enhanced volume rendering display applies linear 3D re-sampling and stack 2D algorithm to enhance the texture of the volume rendering display.
New enhanced Text/Html display avaiable under Displays > Special for displaying straight text or HTML, the display can be added to the view window legend panel for descriptive text about the display.
When doing the image capture we replaced the original screen capture APIs with Java Canvas3D “OffScreenRendering” to improve the image quality. Keep Java Robot screen capture APIs only when the IDV legend and Full window is needed. Replaced JPEG with PNG as the base image format for the animated movie.
3D cross draws a symbol for a location point indication, it is a very simple graphic elements and the large numbers of symbols can be displayed with it. 3D cross symbol can be colored by the value of numerical attribute of the location.
Scalloped line draws boundaries for the significant weather chart. This new drawing feature has been added to the drawing control and could be applied to the demarcation of significant weather.
The new GFS dataset collection has mixed accumulation hours in the time axis for each time step and the previous logic in the IDV picks the first one in the list, unfortunately, always the longest one. So the new logic will try to pick the shortest accumulation hour for each time step, and what we got are 3 and 6 hours for GFS one degree or 0.25 degree, we can use the subtraction to get the 3-hour time step accumulation. This change has been added as a derived variable named: TimeStepAccumulatedPrecip. In general, this formula can be applied to other mixed interval parameters.
