Hi,
Thank you very much for your reply. It seems that I would have to deal
with the input data once again.
Is there a way for the surface to be modified in such way that you have
stated? Would you suggested starting to look at vtk/CGAL codes or
something similar?
Best regards,
Quang

Quang,
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.
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.

Subject: [EXTERNAL] Re: [Paraview] Create 4D Animation from sets of 3D
Data
Hi,
Thanks for your reply.
1) The data sets are all in STL format.
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?
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.

Hi,
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.
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.
Would anyone be kind enough to give me some advices on this,
please?
Thanks,
Quang
