try using mark/compute/unmark instead

--------------------

mark mark mark
(x col) (y col) (z col)

-------- | --------
| | |
compute
[a,b,c]
|
(optional scale module)
|
unmark
(positions)
This flags the x, y & z columns to feed the compute module with 3 active
values. The compute module then returns these three columns as a 3-value
vector. As I use lat/long/metres as my xyz, I add a scale module to make
the 3 axes appropriate scales. The unmark creates a new virtual column
called positions, which contains the 3D position for each row for
displaying.
I think this approach will do what you need.
