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>
