Chris was right: I did mean "Import" (not "Input"), and I should have been
using {Select} to provide the 1st field of what was actually a group. Sorry
about that.
I now have 2 identical instances of {Select} connected to the 1st 2 inputs
of {Regrid}. The object they transmit consists of 3-vector positions and
3-vector velocities. Including {Extract} only causes errors. I no longer
get an error message from {Regrid} but it does not create a 'connections'
component.
I wonder if the 2nd input parameter to {Regrid} (namely "grid") has to
possess a 'connections' component already? (If so, this would appear to
contradict the statement in Chapter 2 of the User's Guide: "If you do not
have connection information available, you can use the Connect or Regrid
modules to create connections for scattered point data.")
Alternatively, maybe trying to fake {Regrid} out by using the same input to
both tabs causes it to do nothing (?). (I could try inputting a greater
number of positions to the 2nd tab, which I plan to do anyway.)
Can anyone point me to a more sophisticated example of the use of {Regrid}
than that in "Samples\Regrid.net" (preferably 3-D)?
Thanks!
