<div class="moz-cite-prefix">Thank you very much David,<br>
this is a good example, I need to study it , but I think I can
make it work for my needs.<br>
<br>
In this example has been used the
vtkInteractorStyleTrackballCamera<span class="br0"></span>Marco,<br>
can I use just the camera position and the object position?<br>

Hello All,<br>
I have the following problem.<br>
I need to calculate and possibly save the information
about a 3D object<br>
from a determined view.<br>
For example if I have a cube I can get the QualityMesure
of the mesh on<br>
the entire object.<br>
I want to calculate the QualityMeasure just on the visible
part of the<br>
object, from that camera position.<br>
Then I'd like to save the visible part of 3D object, but
not as image,<br>
instead as PolyData so I can still get the QualityMeasure.<br>
Or as MetaImage, but I don't know if I can still get the
QualityMeasure<br>
from a MeatImage format.<br>
<br>
I'm new with vtk and I still have some problem to use all
the data<br>
format of the library.<br>
<br>
Thank you very much for your help<br>
<br>
I'd like to know how can be your approach at this problem<br>
<br>
Marco<br>
