Do you mean quadralateral cells in 2-D polar coordinates, of tetrahedral cells (i.e. 4 vertices each) in 3-D spherical coordinates?=20 > From HDF5 user's guide > (http://hdf.ncsa.uiuc.edu/HDF5/doc/Dataspaces.html) > i guess that "complex data space" may help me to represent my data, > but the manual says "Currently only scalar and simple dataspaces are=20 > supported with this version of the H5S interface". >=20 > I'd like to know if i'm right in the dataspace type i should use, > and if yes are complex dataspace available today ? > (the document is dated 14 October 1999) We are not experts in HDF. In any case Vis5D can only display data with regular grids. However, our VisAD system can display irregular data (go to the URL in my sig, and click on the VisAD link). VisAD is for developers rather than end users, and requires some programming in Java. Note that VisAD's interface to HDF5 includes non-Java "native code" (C++) and may not handle that data type you are contemplating (the HDF5 interface to VisAD was written by NCSA and I am not sure of its exact capabilities).
