And another quick thing I slapped together: First, you render an animation
with as many frames as you like. Then, using a somewhat lower number of
frames, I render the animation again, this time using the former frames as
basis for averaged textures: voila, Motionblur!

For now, it only supports looping animation, but I want to work on the code
to make it more flexible, useful for non-looping animations, using weighted
averaging etc. I know, I know, there's Warp's Targa Averager out there, but
I like to do things myself and try to do them based purely on POV-Script.

Anyways, this was just a proof-of-concept. I'll enhance it once I need it
for animations...

Regards,
Tim

PS: Additionally, I wanted to announce that I'm back to Poving... :-)

You may want to talk with Sascha Ledinsky.  He is writing a Java Motion 
Blur app with some neat options.

Discussion:
http://www.imp.org/forums/topic.asp?TOPIC_ID=262

Examples:
http://3dimensions.dhs.org/imp/motionblur/

After he cleans up the code a bit, it will be released as GPL with the  
package IMPTools:

Hm, from the discussion on the forum I can't really much tell if what he's
doing is far better than mine (aside of my approach having to use POV-Ray to
render the images, instead of throwing them out at the fly...). I'm using
two methods of judging which frames to average: cyclic and non-cyclic. And
the remaining bit is done by itself: give the script the amount of frames
the original animation has, and how many you want to end up with, and it'll
render that.

I like to keep things inside POV-Ray unless there's no other way (or unless
it is really completely inefficient sticking to POV-Ray), so...

Thanks for the note though, might want to have an eye on that and copy-paste
the ideas mentioned there... ;-)

For "purely on oldMegaPOV-Script" see:
