Yes. Or you can interpolate and the pass the result to the itools, in
case you do not want to do things interactively every time:

triangulate,elevation,azimuth,tr
response_2D=trigrid(elevation,azimuth,response,tr,xgrid=el_g rid,ygrid=az_grid,nx=200,ny=200)

(just guessing at 200 grid points, obviously; you need to find out
which grid resolution is most appropriate)

then you could do

iimage,response_2D,el_grid,az_grid

Or similarly with isurface or icontour.
