Density index to coordinates:

	int NUM_x = 200, NUM_y = 200, NUM_z = 600, DX = 10;
	z_ind = floor(ind / (NUM_x * NUM_y) );
	y_ind = floor( (ind - z_ind * NUM_x * NUM_y) / NUM_x );
	x_ind = ind - z_ind * NUM_x * NUM_y - y_ind * NUM_x;
	x_coor = DX*x_ind + .5*DX * (1. - NUM_x);
	y_coor = DX*y_ind + .5*DX * (1. - NUM_y);
	z_coor = DX*z_ind + .5*DX * (1. - NUM_z);

	- Note, the coordinates are Euclidean coordinates in the center of the grid.
