The POV-Ray format is used to store a scene description language used by the
POV-Ray ray tracing software package. POV-Ray files are always ASCII to allow
easy transportation between different file systems.

The specification for the POV file format and scene description language is
found in the file povray.doc in the POV-Ray distribution. You may obtain
this file (and the entire POV-Ray package) from the official POV-Ray FTP
archive and Web sites: 
  
  ftp://ftp.povray.org/pub/povray/Official/docs/
  http://www.povray.org/pub/povray/Official/docs/povdoc-2_2.zip

or from these official mirror sites:

The following is an excellent book on ray tracing using the POV-Ray tracing
software package for the PC:

It is also worth noting that not only is POV-Ray an excellent ray
tracing package, but its source and binaries are availble for most
systems and widely distributed free of cost.
