collapsing 3-d arrays [message #6505]

I have a pretty large 3-D data array (~10 million pts). I'd like to
collapse
the data and look at a 2-d image that contains the max value encountered
along the third coordinate. I can write a nested loop that
looks thru the array and pulls out the max data value along the z-axis
for each
x,y coordinate pair, but that's pretty cumbersome. It seems like IDL
should have
a built-in function for doing this kind of thing, but i can't seem to
find it.
The project_vol command looks like it might do what i want but i can't
seem to
convince it to give projections along the (x,y), (x,z) and/or (y,z)
planes..it
does some weird pseudo-isometric thing. Does anyone have any hints on
how to
accomplish this efficiently within IDL?
