Hello to all train heads,
since some life has returned to Lugnet.trains, I may use this opportunity to
give a little info on my latest render experience.
A few weeks ago I was looking for motion blur effects (to generate more realism
in animations rendered in PovRay). Thus I found this thread, that had been
published at Lugnet more than 10 (!!) years ago:
http://news.lugnet.com/cad/ray/?n=230 At that time I had not even installed
LDraw on my PC and from today’s point of view it appears still a small wonder,
that nobody has been working on that effect since then (if so I have definitely
missed it)....
That picture of an airplane is still pretty cool and I had to install Megapov to
imitate that 10 yearss old effect on my own, which has been described in this
1000steine thread:
http://www.1000steine.de/1000steine/forum2/forum_entry.php?id=228176 (in
German language but only the pictures are of any importance anyway).
After this fast success I tried something more advanced (as if a steam train was
being more advanced than a airplaine... => at least it has more moving parts).
Today my latest picture (including 8-step motion blur) has been rendered through
after more than 4 days of render time.
The same picture without motion blur takes less than 90 seconds.
Rendering this 8 times and fuse them in a graphic program (in my case I have
used picture publisher 8.0 - a (very) cheap 10 years old program I own) appeared
to be more efficient.
But even if a macro is used to create 1 picture from 8 ones, this is a huge part
of manual work to generate some hundreds of pictures as needed for a short
animation.....
If anybody knows a free software to create automatically many fused graphic
files, please let me know.
Hope you enjoy + Leg Godt!
