[Vis5d-users] Re: Underwater Topo

Hi NG,

My guess is that you still have the follwoing code in
your maketopo.c:

   for (r=0;r<ROWS;r++) {
      for (c=0;c<COLUMNS;c++) {
         if (Topo[r][c] <= 0.0) {
            Water[r][c] = 1;
         }
         else {
            Water[r][c] = 0;
         }
      }
   }

This sets the "Water" flag wherever the topo is below sea
level.  Change it to:

   for (r=0;r<ROWS;r++) {
      for (c=0;c<COLUMNS;c++) {
         Water[r][c] = 0;
      }
   }

Good luck and happy holidays,
Bill
