<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> Okay, not sure what is going on here. I have an image stack that is pretty dark with a semi-white blob in the center. I would like to be able to select any point on that blob.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> I find that I can do this, if I turn the pickable setting of the volume off, and create an isosurface for the semi-white blob. However, ideally, I would prefer to just use the vtkVolumePicker to select the blob, rather
than having to spend the time creating the isosurface.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> When I try to click on the white area of the blob, I always get the edges of the volume. Is there a way to ignore the volume’s dark areas? Since I don’t know what the exact pixel values are, is there a way to define a
range of pixels to ignore (i.e. ignore all pixels < 10 and pixels > 100)?<o:p></o:p></p>
