Welcome to VisIt's release notes page. This page describes the important enhancements and bug-fixes that were added to this release.
Features added in version 1.3
Each database with multiple time states now gets its own time slider that you can use to set the time independently for each database. This allows multiple, unrelated, time-varying databases to coexist in the same visualization window. When there are multiple time sliders, the "Active time slider" chooser appears above the animation slider in the SUI's main window. Select a different time slider if you want to change time states for that database.
If you want to lock the plots from multiple databases together in time, you can create a database correlation. A database correlation is a mapping that relates the time states from one or more databases. There are currently 4 correlation methods: padded index, stretched index, time, cycle. Padded index correlations choose the database in the correlation with the most time states and repeat the last state from all shorter databases until they are all the same length. A stretched index correlation also chooses the database with the most time states but instead of repeating the last time state from the shorter databases, their time states are stretched until all databases in the correlation have the same length. That way, time states are repeated in the middle of the correlation instead of at the end. Time correlations create a list of all times from all database time states and then create a mapping of time states to match the times that are shown. Cycle correlations work in the same way but use cycle instead of times.
If you want to create a database correlation, open the Database correlation list window in VisIt's Controls menu. Once you open the window, click the "New" button to create a new correlation in a new correlation window. Once the new correlation window appears, you can choose the name and correlation method for the new database correlation. You can also add databases to the database correlation. When you create a database correlation, VisIt creates a new time slider for the new correlation and makes it the active time slider. When you change the time slider for a database correlation to a new state, all plots that have databases that are part of the database correlation are affected and have their states updated according to the database correlation. You can switch between time sliders at any time if you do not want to set the time state using the database correlation's time slider. You can also delete or alter database correlations.
The Database correlation list window allows you to create or edit database correlations but it can also be used to set the conditions under which VisIt will automatically create database correlations. By default, VisIt will prompt you to before automatically creating a new database correlation if you add a plot from a database that has the same number of time states as a plot that is already in the vis window. You can make VisIt never/always/sometimes create new database correlations when adding plots. You can also set the default correlation method and whether you want to be prompted before the new correlation is created.
When you lock windows in time, VisIt attempts to create a database correlation for databases in all of the locked windows. This ensures that when you change the time slider in one window, it has meaning to also change it in the locked windows.
