Dear James,<br>thank you for the tips.<br><br>I am trying to figure out if your vtkImplicitPolyDataDistance class contribution would help me somehow solve the issue. <br><br>Would you be able to post some simple example on how to use it?<br>

</font> </div><div><div class="h5"> <br><div>Hi there,<br>I am facing some problems with a boolean filter (vtkBooleanOperationPolyDataFilter) applied to a pair of vtkTubeFilter. The thing is that for my application the vtkTubeFilterfits better than a vtkCylinderSource. Besides, I want the capping property of the tubeFilter to be off.<br>
<br>I use a vtkTriangleFilter in order to transform the tubeFilters into objects that the boolean filter can deal with.<br><br>When performing an intersection boolean operation, it seems like capping is necessary in order to get acceptable results. However, since I cannot erase the cap to the actor yielded by the boolean operator, this is not a good solution.<br>
<br>On the other hand, I can give some "thickness" to the tubeFilter by creating an "inner" tubeFilter and then applying the difference boolean operator. <br><br>However, then the problem is that the inner wall of the resulting actor seems not to have a geometry. Or at least it is not shown. <br>
<br>Setting the backfaceculling property on does not change things.<br><br>I have attached some images in order to clarify things.<br><br>Any guess?<br><br>Thank you,<br>JON HAITZ<br><br><br>
