In that sample scene, yes.

Are you familiar with the game Minecraft?  I'm writing a program that converts a
world created in Minecraft into a POV-Ray scene.  Where the water blocks are can
be somewhat random, and not necessarily in large chunks that can easily be
turned into a single large box or plane.  Bodies of water can be as small as a
single block, or spanning miles across.  Their shape will vary just as much.
