Yes it is, I set it as a constant so I can try different values.

It's not interactive. I'm using this project to learn C++ so I shell out to my
programme to create a heightfield. I found that the parsing time in SDL was too
long. Your system looks much better. For this project I want to create waves
around a footstep of a walking figure so I want to have a large array/
heightfield. I export a mesh from Poser and import it into POV. I'm playing with
BVH motion files, see my post in moray.binaries (called Spinkick something). As
for reading pgm files, they are text files so they are simple to read using
fileio. One thing to point out is POV does not read comment lines as per the
file specs. I don't know what you mean about setting the water surface different
than on a horizontal plane. In my world water is level :-) 
Blocking objects are not in scope but I have an idea or two using an overlay. As
they say on Mastermind I've started so I'll finish.
