<font size="-1"><font face="Verdana">Hi everybody,<br>
this is probably a trivial question, but after half an hour of
navigation into the documentation, I think I got a little bit lost. The
point is:<br>
- I have a vtkPolyData and I want to intersect it with a line<br>
- I was trying to recycle a similar function I wrote which was cutting
the mesh with a plane with vtkCutter, but there's no implicit function
defining a line<br>
<br>
can somebody give me a hint, or few lines of code hot to perform this
operation? (e.g. by defining start-endpoint of the line/segment)<br>
<br>
regards,<br>
a.<br>
