What is the currently supported / generally accepted parallel implementation of
povray to render, for example, on a linux cluster? I'm looking for a visual
demonstration to persuade potential users to consider running their engineering
codes on a cluster versus individual node.

At the moment there is no official solution for distributed POV-Ray 
rendering. Inofficial approaches usually use POV-Ray's command line or 
INI file interface to have each node render only a subset of frames in 
an animation, or only a rectangular portion of a still image.

nothing supported/generally accepted, as clipka pointed out, but one of the
POV-Ray "regulars" runs a small render farm on his network, based I understand
on custom written software.  not the same as a cluster of course, but have a
browse for posts by "Dik Balaska"[*], they often have links to his
projects/site.

[*] although regular, I haven't seen a post of his in the last few weeks, RL I
guess.

I and my family have been sucked into Minecraft. I'm still reading here,
I just
haven't had much to say, and there's been no progress on my animation.

I appreciate the quick feedback!  Is there an option to display an image while
it is rendering?

I'm testing with this after running the samples:

with a "normal" installation that is the default.  does adding command-line
option '+D' help?
