Personally, I would be interested to have 'motion blur' (available in 
megapov) included into version 3.7.

What do you think?

I can do without (as proven in the "Dragons" TC-RTC round :-P).

But if someone would want to implement it, I wouldn't want to discourage 
them either.

(Not me though - that's quite a definite.)

Yes, I noticed indeed. I think I know how you did that... :-)

Unfortunately, not me either :-(  it is beyond my capacities.

Hm... I thought about it: Aside from doing motion blur, I guess the 
mechanism could also be used to create objects which are transparent, 
yet at the same time completely opaque with respect to themselves (if 
you get the meaning), which would make for a great mechanism to render 
"dreams" or "ghosts" into an image.

Which is something I'm probably more in for than motion blur.

I could take it or leave it, since there is a way which works quite well 
already. You probably know about it. You render a bunch of frames and 
simply average them together in another scene. You can get away with 
only rendering the motion-blurred object many times, while leaving the 
rest of the scene untouched since POV can read partial images. 
Everything can be spliced together using boxes and an orthographic 
camera, or rendered into the actual scene geometry using Rune's 
illusion.inc (which is harder).

It's not really easy, and setting up a scene in this manner can be 
cumbersome.

That is how MegaPOV does it.

Yes indeed, and that is why the Motion Blur patch in Megapov is so easy to 
use: it does exactly that all by itself without interference from outside.

So, why do it the hard way when it can be done in a simple straightforward 
way?

Ghosts would be great too... :-)

I did not know that...

Because you need to finish a render *now*, and can't wait for it to be 
implemented?

I get a bad feeling from everyone here lately. Maybe my meds aren't 
working right or something.

Don't worry .... you're not the only one!

Kind of like a bad soap opera ... huh?
