I see now that it’s just a matter of using multiple Clip filters, using planes with orthogonal normals, resulting in the desired boolean set of points. Still need to figure out how to cap the clipped glyphs though…<div class=""><br class=""><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Oct 17, 2017, at 3:55 PM, Heiland, Randy <<a href="mailto:heiland@iu.edu" class="">heiland@iu.edu</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><meta http-equiv="Content-Type" content="text/html charset=utf-8" class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class="">Thanks. Actually, I did a poor job explaining what I want to do. I’d like to have *partial* clip planes (as opposed to “infinite" planes over the entire domain). More specifically, my current use case is a bunch of spheres (representing biological cells) inside a spheroidal tumor. I’d like to cut out an octant, for example, from that spheroid to be able to peer inside better.<div class=""><br class=""></div><div class="">I’ve mocked up an example, using random points, and put the PV state file at <a href="https://github.com/rheiland/paraview_play" class="">https://github.com/rheiland/paraview_play</a> (along with some sample /images). I just used the Box option of the Clip filter, because the Plane option seems to define an infinite plane (via Point and Normal). But the Box params (Position, Rotate, Scale) is not intuitive for my use case. Ideally I’d like to be able to specify a Corner and 3 Vectors. And, eventually, I’d like “cutter” results, where the spheres/cells are actually cut and capped.</div><div class=""><br class=""></div><div class="">So perhaps, I need an alternative pipeline for my use case. Suggestions welcome. For that matter, am I mistaken in thinking I can do what I want using OSPRay spheres?</div><div class=""><br class=""></div><div class="">thanks! -Randy<br class=""><div class=""><br class=""><div class=""><blockquote type="cite" class=""><div class="">On Oct 17, 2017, at 8:37 AM, Mathieu Westphal <<a href="mailto:mathieu.westphal@kitware.com" class="">mathieu.westphal@kitware.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><meta http-equiv="Content-Type" content="text/html; charset=utf-8" class=""><div dir="ltr" class=""><div class=""><div class="">Hello<br class=""><br class=""></div>It is called Slice, and is available in the Filters and in the Common Filters toolbar.<br class=""><br class=""></div>Best,<br class=""></div><div class="gmail_extra"><br clear="all" class=""><div class=""><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr" class="">Mathieu Westphal<br class=""></div></div></div>
