Hello all,
Does anyone have an idea how to suggest motion in a scene?
I am trying to make a still scene showing a steam engine at work. I want to
suggest a motion blur on the flywheel and the crackshaft, and probably on
the transmission belt.
Any ideas or examples?
Frans

Take a look at the picture in povray.binaries.pictures
subject line: Fur
It's a picture of a teddy bear using the new density map function
to create fur. It also looks like a possible method of imitating
motion blur.
Good luck and let us see the results.

You can do similar averaging (like Warp's) with Paint Shop Pro v5 but on any
type of image.

there is a little known motion blur patch for 3.0x by Ron Parker. I can
e-mail you a copy if interested.

But only two images at once...
To average, for example, 13 images with PSP would be a challenge
if each is to be weighted equally.
I believe ImageMagick (UNIX), via the combine statement, can
do weighted averages. This excellent package is really a must
for folks doing image manipulation in UNIX.

Yeah, render a short animation showing the moving parts of your scene
moving as they would over a very short period of time. How much each object
moves is dependant on how fast you want them to appear to be moving. Then,
when you've rendered the animation average all the frames together into a
single file. There are many utilities and image manipulation apps about
that'll do the averaging, DTA (Daves Targa Animator) springs to mind, I
don't have a URL for it, but I _think_ it's on ftp.povray.org.

Is DTA already capable of handling more than a few thousands of kilobytes
of data?

I don't know, I've only ever used it for relatively small animations.

Go to my homepage listed below and download the short utility "Warp's
Targa Averager" from my downloads page. It will produce a single
averaged image from a multitude of initial targa images. There is no
PSP required or anything else.
My site has the Win95 console version of the utility, and there is a
link to Warp's original site that has a DOS version. Original source
code is included to port the utility to Linux or whatever one needs.
An additional note: the utility can also create "delta images", which
are the result of subtracting one image from another. This can be used
on a series of animation frames in an attempt to reduce their storage
requirements for lossless archiving, etc. The "delta frames" will need
to be unconverted before being viewed normaly, but Warp's utility can
also perform this restoration. This is a somewhat experimental
feature, in that delta frames are not a standard storage format. Warp
was nice enough to add that feature at my request, so I could perform
some tests of delta frame effectiveness. With some animations, it does
help reduce lossless storage requirements considerably when combined
with lossless compression techniques.
