Hi,

The current Version of pov allows to read/write files.

This is the same as reading/writing database-entries.

Just with a "real" database, you can handle more different items very
easily.



What you could do, is to write a script e.g. in PHP, and use it's
database-functions.
This script might be used to write an .inc -file, that directly can be
included by povray.

you can find a quite old program (pov-shell002) written in Gtk-Perl, that
generates Pov-Scripts to display Diagrams (I never finished it, I just
mention  it to give an idea).

Instead of typing in diagram-data, you might read them in with the
sql-functions of perl.

Greets, Mark

I did something like that using python and pySQLite. The one thing it does 
not give you is interaction with the elements of the scene while parsing.
