of simplifying the construction of a multi-scalar netCDF volume=2C but clea=
rly involves a lot of extra manipulation.<BR>
 =3B<BR>
The thing to really ask is if you have a file giving a position in the data=
volume (XYZ) and one or more scalar values at the given position=2C in an =
ascii file (e.g. CSV) is there a simple way of getting the data into Paravi=
ew as a true volume dataset?<BR>

is is a very broad-based query but would like to get some <BR>>=3B >=3B=

to <BR>>=3B >=3B generate a volume of data=2C as opposed to just a ser=
ies of layers? As I <BR>>=3B >=3B see it=2C I need to get the data into=
a format like XYZ (for position in <BR>>=3B >=3B the volume) and then =
one or more variables to describe the scalar <BR>>=3B >=3B function at =
the given position.<BR>>=3B >=3B <BR>>=3B >=3B Presently=2C I could=
export ascii XYZ data from GMT to generate say <BR>>=3B >=3B x=2Cy=2Cg=
ravity at level 0=2C and then x=2Cy=2Cgravity at level 1 etc...but it <BR>&=
gt=3B >=3B does seem that Paraview expects the data in a more structured =
and <BR>>=3B >=3B defined format=2C with which to generate a volume.<BR=
>>=3B >=3B <BR>>=3B >=3B There is a "roundabout" way to get netCDF =

Z)=2C and not build a volume from a series of layers.<BR>>=3B >=3B <BR>=
>=3B >=3B I think it would be useful to at least have a in-depth tutori=

Paraview and the <BR>>=3B >=3B construction of data volumes from 2D inf=
