Re: capture images in the animation loop

Hi everybody !

I actually played for a while with this, in a somehow different context. Basically I wanted to playback the user interaction with a 3D display. So I recorded the changes in the projection control of the display plus the timing and then I just rendered them either in AVI or QuikTime format (both supported by jmf). The nice think is that I could load the display with a simple scene, record the user interaction (rotation, translation, zooming etc.) and then render the movie with a scene loaded with all the details.

If anyone interested I can actually spend couples of days ( week-ends ;-) ) on :
1 - VisAD file form for JMF supported media types
2 - a simple playback module - useful for presentations (design suggestions are more than welcome)

Cheers,
-iulian

Hi Andrew,

As far as I know, no one has written a VisAD file form for
Java Media Framework supported media types. If you were to
write one, it would be a great asset. Actually, I may end
up writing one at some point in the future, precisely so
that VisAD would support QuickTime on a larger number of
platforms.

This is a very nice solution for creating QuickTime movies

I am working on UNIX. Is this solution only available on
Windows and Mac?

Has anyone a solution that uses the Java Media Framework?

Hi Helen,
If your data is a timestack of images, such as with MathType:

   (time -> ((x, y) -> value))
Then you can export it as a QuickTime movie using VisAD's
QuickTime file form.  See the main method of
visad.data.qt.QTForm
for an example.

Also, note that to use the QuickTime form, you must have
QuickTime for Java installed on your machine.  You can find
it for
Windows and MacOSX at:

   http://www.apple.com/quicktime/download/

Be sure to choose a Custom installation and specify
"QuickTime
for Java" as one of the selected components.

Hi

Is it possible to capture the animation images ( if  4

frames) into one

file, such as MPEG file? How?

Thanks,
