I had to do the same once. Here is how it works, in my case :
  _ i create 2 pipes : 1 for povray text output ( to catch error messages,
  stats etc... ) and 1 for image raw data.
  _ i launch povray with +GApipe1 +Opipe2 +FP
  _ i also launch 2 threads to read each pipe
 
You know render is over when you got all image data, but you have to
relaunch povray for each image ( you can use the same pipes i think ). I
guess you can do without threads if you don't need to catch error message,
cancel render etc... it would be really more simple :)
