Hello Marko,<br><br>
We have encountered clipping problems with the VolumePro 500, but we have
not (recently) encountered problems with cropping. One test you
might want to try is to download the evaluation copy of VolView, load in
your volume, and play with the cropping. You can toggle between standard
(ray casting / texture mapping) rendering and VolumePro rendering. If you
can reproduce the problem in VolView, then let me know the size and type
of your data and I will try the same experiment here, and perhaps pass it
along to TeraRecon.<br><br>

<font face="arial" size=2>i have some problems to do cropping with a
VolumePro500. I have already implemented cropping with
software-raycasting but when I switch to the VolumePro-Board I only get a
black window. Without cropping all works fine.<br>
</font><br>
<font face="arial" size=2> <br>
</font><br>
<font face="arial" size=2>To enable cropping i do :<br>
</font><br>
<font face="arial" size=2> <br>
</font><br>
<font face="arial" size=2>m_pVolumeMapper->SetCropping(TRUE);
//m_pVolumeMapper is a vtkVolumeProMapper*<br>
</font><br>
<font face="arial" size=2>m_pVolumeMapper->SetCroppingRegionFlagsToSubVolume();<br>
</font><br>
<font face="arial" size=2>m_pVolumeMapper->SetCroppingRegionPlanes(100,200,100,200,100,200);<br>
</font><br>
<font face="arial" size=2> <br>
</font><br>
<font face="arial" size=2>The center of my volume is at (150,150,150) and
with Software-Raycasting the crop-volume is as expected around the
center. <br>
</font><br>
<font face="arial" size=2> <br>
</font><br>
<font face="arial" size=2>I also tried SetSubVolume:<br>
</font><br>
<font face="arial" size=2>((vtkVolumeProMapper*)m_pVolumeMapper)->SetSubVolume(100,200,100,200,100,200);<br>
</font><br>
<font face="arial" size=2> <br>
</font><br>
<font face="arial" size=2>But this did not have an effect at all, the
whole volume is rendered. Has the SubVolume rendering to be enabled? But
How?<br>
</font><br>
<font face="arial" size=2> <br>
</font><br>
<font face="arial" size=2>Has anybody an idea?<br>
