319 | | Physical fields can be defined either on regular grids, either scattered on an unstructured set of positions. Some measurements techniques, like PIV or particle tracking, provided unstructured data, while most methods of analysis require data on a regular grid. This can be done by interpolation, defining a projection on a plane (with '''[!ProjMode='interp...']''', see [#ProjObject next section]). The three possibilities of griding are defined as follows: |
