Lee,
This is not a bug. What you are seeing is what you should expect. Please
carefully read the section on "phase" in the POV documentation. The phase
modifier essentially "rotates" your color_map. When rotated, the 0.0=0.0
and 1.0=1.0 end up right next to each-other, so they create a discontinuity
in the function. That discontinuity produces a vertical drop/rise in the
height-field.
If you change your color_map to the following, then things will look more
like what you'd expect.
color_map {
[0 rgb 0]
[.5 rgb 1]
[1 rgb 0]
}
