Vertical soundings.

Hi:

Im trying to visualize vertical soundings of my 3D data in a 2D display. I`m able to do it with no animation, with this types:

   (xCoord, yCoord, zCoord) -> concentration

and the verticl is displayed when i move a cursor around the 3D display.

But i need to animate the display, and i want the vertical sounding to change not only when i move the cursor around; i want it to be displayed when the time changes, although i dont move the cursor around.

The types will be these:

   time -> ( (xCoord, yCoord, zCoord) -> concentration)

Thank you so much. Waiting your answers...
