Some precisions for Kendai:
1) examples/buldozer.py with
utils.encodeVideoFromFrames(snapshooter['savedSnapshots'],out='/tmp/buldozer.ogg',fps=30)
It creates video from the current view
This uses SnapshotEngine to save .png from the current view every few
steps during the simulation. snapshooter['savedSnapshots'] is list of
filenames, which are converted to view file by the command Anton has
mentioned.
The other possibility is to save partial simulation state (positions and
orientation of bodies); there are 2 engines for this: (i)
SQLiteRecorder, which saves into a single .sqlite file periodically. You
can use Yade's player to replay the simulation afterwars; the player is
able to save snapshots as well, which can be used to create the video.
(ii) VTKRecorder, which saves into a series of .xml files in VTK format,
which is useful if you want to use VTK-based visualization tools such as
Paraview:
2) examples/buldozerVTK.py (added in r1770) uses VTK-recorder. Creates
periodically snapshots in VTK-files. Then you can use the Paraview to
render the video or any other VTK software.
Cheers, Vaclav
