When I import a Surfer grid into Voxler, I am prompted to load the grid as a uniform lattice or a curvilinear lattice. What is the difference between the 2 options?

When I import a Surfer grid into Voxler, I am prompted to load the grid as a uniform lattice or a curvilinear lattice. What is the difference between the two?
 

The difference between the two options is the Z value assignment. The Import as uniform lattice option assigns the Z value of the grid to the C component value and assigns the Z component a value of 0 in the Voxler lattice.

The example above is the BoulderColorado.grd imported as a uniform lattice.  This grid file can be found in C:\Program Files\Golden Software\Voxler 4\Samples.

 

The Import as curvilinear lattice option assigns the Z value of the Surfer grid to the Z and C component values of the Voxler lattice. 

The example above is the BoulderColorado.grd imported as a curvilinear lattice.  This grid file can be found in C:\Program Files\Golden Software\Voxler 4\Samples.
