[vtkusers] How to produce movie file?

[rakesh patil]

Dear VTK Users,

Please pardon me for re-posting the question. How do I produce the movie
file using vtkAVIWriter? I do have written a code and it produces animation
file without any problem. When I wanted to present this animation in
powerpoint, it so happened that, full animation played without any problem.
But what I observed was that at the beginning of the video and at the end
of the video, black screen is displayed. Is this an expected behavior of
vtkAVIWriter? If not how can I remove the black screen?

Below is the code I have used.

vtkWindowToImageFilter *windowToImage = vtkWindowToImageFilter::New();

windowToImage->SetInput(pRenderWindow );

windowToImage->SetInputBufferTypeToRGBA();



vtkAVIWriter *avw = vtkAVIWriter::New();

avw->SetInputConnection(windowToImage->GetOutputPort());

avw->SetFileName("animation.avi");

avw->SetQuality(2);

avw->SetRate((int)srate);

avw->Start();



double tIter = startIndex;


while(tIter <= endIndex)

{

       /* Code to Display Results (Contours and/or vectors) */





       windowToImage->Modified();

       avw->Write();



       /* Code to increment the counter */

       tIter += timeStep;

}

avw->End();



avw->Delete();

windowToImage->Delete();


Urgent suggestions/help required.


Thanks in advance


Regards
