<div>First before answering your question, let me alert you to an easier way to load your data into ParaView. First, name your files with numbers just before the extension (e.g. left_ventricle_00.stl, left_ventricle_01.stl, left_ventricle_02.stl, etc.). Then
just load this file series as one unit (they will be grouped in the ParaView file browser) and ParaView will automatically animate them; no need to add them manually with the Animation View.</div>
<div><br>
</div>
<div>Now the bad news. I don't think the Temporal Interpolator is going to work with your data. The Temporal Interpolator needs a way to register where a point in one time step goes to in the next time step. It does this in a very simplistic way by assuming
the topology is consistent across time steps. That is, each data set has the exact same triangles listed in the same order connected the same way but at different positions. The surface from your segmentation is surely not of this nature.</div>

<p dir="ltr">Hi,</p>
<p dir="ltr">Thanks for your reply. </p>
<p dir="ltr">1) The data sets are all in STL format. </p>
<p dir="ltr">2) I am not very sure about this. After using text editor to open the mesh file I can say that they are not... Is there anyway to change this?

1) What file format are the 10 data sets in?
<div>2) do all meshes have the same number of points and cells and do the come in the same order in every timstep? temporal interpolation requires a 1:1 correspondence so that it knows what to interpolate between.</div>

Hi,<br>
<br>
I have a group of 10 data sets of the left ventricle at different cardiac phases. They have been 3D reconstructed using segmentation method. Now I am trying to use ParaView to see the dynamic changes over different cardiac phases.<br>
<br>
I have been able to get to the View -> Animation mode and add each 3D data at different time, but they only show me a jump from one data to another, rather than 'deforming' into another. I have done some searches on the internet and found someone suggesting
the use of 'Temporal Interpolator' but failed to utilise it.<br>
<br>
Would anyone be kind enough to give me some advices on this, please?<br>
<br>
Thanks,<br>
Quang<br>
