AVI recording and offline parameter settings

[Gladsomebeast]

In Vizard 3.0 you can press CTRL-F12 to toggle avi recording of what is on the screen.

Check out the examples in Vizard30/examples/file_io for how to write to files.

Hi,
Thanks for the AVI recording details.Seems like this process takes a huge amount of disk space.A particle simulation example takes huge amount of physical memory(as the particle numbers grow).The vector method of recording the simulation looks a better option.Can some one please comment on the following

1) how can I configure to run the world view recording for a specified amount of time?

2) can this be done without the worldview window being displayed?(in background)

Thanks in advance

I'm trying to do something similar. We're reading in a buffer of data and playing it back on the screen as an animation, and we'd like to save the animation as an AVI file from the first display of data to the last display. However, I can't quite figure out how or where Ctrl-F12 saves the file in 3.0a. And I'm not sure how to incorporate write.py with my code (ie, where to put the call to start recording and end recording). Any ideas?

CRTL-F12 creates an avi file in the same directory as the script you are running. There is no Python command to start AVI recording.

The file io stuff is about using the Python file fucntion to write text. It not related to AVI recording.

Is the Control-F12 functionality available in the version of Vizard we have (3.0A)? It doesn't seem to work for me. Is there also a programmatic way to start and stop the recording (ie, make Vizard think that a Control-F12 is pressed each time through a for-loop?)?

Hi,

I am referring to the world view window which appears after pressing the "run" button in the vizard window.This window appears for some time and terminates unexpectedly. My world never appears. rather I see the ball-head swinging for some time.The workaround is to reduce the number os "particles".after this , my world displays in the world view window and the simulation works fine.

I am testing this in a uniprocessing environment, Intel 2ghz processor, Intel extreme graphics processor and Windows XP.Can you please suggest any workarounds?Ideally this should work(trading off performance) :-)

Thanks,
