TUFLOW Viewer: Difference between revisions

<b>''A few notes on the recommended QGIS version:''</b><br>

* TUFLOW Viewer is developed using the latest version, and although backwards compatibility is maintained as best as possible, TUFLOW Viewer is generally tested mostmore frequently on the latest QGIS version.

* The mesh data provider (MDAL) and the temporal controller (which now underpins the mesh datasets in QGIS) are both relatively new in comparison to other libraries (e.g. GDAL) and are therefore generally updated more regularly updated with new features, enhancements, and bug fixes by the QGIS developers. TUFLOW Viewer takes advantage of these updates.<br>

Although TUFLOW Viewer has been developed in an attempt to havebe consistent behaviour across QGIS versions, it is not always possible. andSome QGIS developments and behaviour changes have led to TUFLOW Viewer behaviour also changing either through necessity or to keep in-line with the QGIS development direction. The below is a current list of known behaviour changes due to QGIS version:<br>

* Prior to QGIS 3.14, TUFLOW Viewer stored all results internally as relative time. and theThe user could display as date-time and the reference time by changing '''Zero Date''' in '''Settings >> Options'''

* QGIS 3.14, TUFLOW Viewer tried to mimmickmimic the behaviour of previous versions but the reference time could also be altered natively in the mesh layer '''Properties'''. Note on this version, this is the first QGIS release with the '''temporal controller''' and as a consequence some of the functionality matured and changed in subsequent versions. Users may experience strange behaviour when using TUFLOW Viewer with the versionQGIS 3.14 if using date-time format. It is recommended to upgrade to later versions of QGIS if date-time format is required.
