Jaron, you must reference EVERY pixels in 3D, not just one..
You can try something like:

n_points = n_elements(xidx)
zIdx = bytarr(n_points)
test3d[zIdx,xidx,yidx] = 1 --> though having X,Y,Z instead of Z,X,Y
would be easier to manipulate I guess

If I remember well there is an article on David Fanning's site, likely
written by JD Smith.
