Yes, that does make sense. Is there any case where it would not be (0,0,0)? I don't see one based on your explanation, but I want to be sure.<br>

Subject: Re: [Paraview] pqMultiSliceView bug?<br>
<div class="im"><br>
The origin is "always" 0 as we rely on the slice offset. So in order to figure out easily where each slice is, it is better to have an origin at 0, so the offset become the location on any slice.<br>
<br>
Does that make sense ?<br>

Hi,<br>
<br>
I'm using the new pqMultiSliceView in our C++ application. Everything seems to work fine except when I use the information from GetSliceOrigin(). It always returns (0,0,0) even when the sliceOffsetOnAxis in the sliceClicked() signal shows the correct slice location on the particular axis. I can create an origin vector using the normal vector from GetSliceNormal() (which is correct), but I think GetSliceOrigin() should return the right thing.<br>
<br>
Thanks,<br>
