[yt-users] combining data objects

[Matthew Turk]

Hi Christine,

You can do this with Extracted regions using the .join() method.
Right now it doesn't work for regular data objects.  However, one
could make up a new data object that does this.  You could create a
new data object:

http://yt-project.org/docs/2.2/advanced/creating_datatypes.html

and have it calculate joins for each of the sub objects it represents
for _get_list_of_grids, return a logical or of _get_fully_enclosed
called on each sub-object, and a logical or for _get_cut_mask called
on each sub-object.  If you do this, it would be awesome if you'd
fork:

https://bitbucket.org/yt_analysis/yt/fork

and issue a pull request with the new object!  There may be some
subtleties with passing field parameters down, but we can deal with
that later.
