I think one of the other responders was on the right track for your
problem. Your glypsh are ending up at z=0. You need to make your glyphs
have positions of x y and z. There are probably several ways to do this,
but here's one. Take your x,y, data field and pass it to "Mark" and mark
the "positions" component. This makes your {x,y} values a data component.
Now pass that to the first input of Compute. Pass the unadulterated
{x,y,data} field to the second input of Compute. Then your Compute
expression should be [a.x, a.y, b]. This will take your x and y's from your
original 2D field along with your "data" and make a 3D field. Take the
output of Compute and pass it to the first input of Construct. This will
make a 3D set of positions for you to use for Glyph. I forget, Construct
may not like the field as output from Compute; you may need to Extract the
"data" component first.
Good Luck!

Please respond to

Thanks for all the response.
I forgot to add in the original message that the Rubbersheet scale is set
to 1.0. The regular grid is x, y with z as the data (all z's are
positive). The points are read in with x, y as position and z as the data
value. These points most likely do not coincide with any nodes of the
regular grid.
