<div>Hi all,</div>
<div> </div>
<div>I’ve got a strange problem with the vtkFixedPointVolumeRayCastMapper:</div>
<div>In interactive mode, it renders my images very accurately, as expected. What I am trying to do, however, is to animate objects automatically to generate a movie. For this, I’ve set up a loop in which I adjust each position and orientation of every vtkVolume
in the scene and then call Render() on the RenderWindow. The results I get for this case look like intermediate previews: largely pixilated, as if rendered in very low resolution. In case I can send attachments over this list, I’ve added two small images below
to illustrate the problem.</div>
<div> </div>
<div>I’ve already tried: </div>
<div>renWin->SetDesiredUpdateRate( 0 );</div>
<div> </div>
<div>to tell the renderer to take all the time he needs, but that did not change anything.</div>
<div>If I activate a vtkRenderWindowInteractor after my loop, a single click in the image triggers an update that leaves me with a crystal clear image, but how can I render at this quality automatically?</div>
<div> </div>
<div>Thanks for any ideas, best wishes,</div>
<div>Tobias</div>
