I'm not sure exactly what you're trying to do, although I kind of get the idea
from the manual/textbook scan you posted.

in "test1M(x,y)\pov1.pov"  I see you are only giving your object a pigment.  If
I understand the goal, you need to use the .red, .green, and .blue components of
the initially rendered image as data for a material map.
I don't see where you have defined a material map in the .pov file.

hit F1 in POV-Ray and look up "material_map" in the index.

I'm lost with this and can't help you.  I've never done anything like that
before.   Maybe someone else can figure this out, or your instructor can explain
it better.

If you have more information, or a reference with more details, maybe I could
offer a suggestion.
