<p>Dear community,</p>
<p><br>
</p>
<p>Is it possible with ParaView to group vtkImageData objects in a single file format? I would like to import a couple of regular grids (i.e. vtkImageData objects) as a single file, rather than as grid_1.pvti, grid_2.pvti, etc... Once imported I would like
to simply select which grid to visualize (with volume rendering). </p>
<p><br>
</p>
<p>I tried the following structures already:</p>
<p><br>
</p>
<p></p>
<ol style="margin-bottom: 0px; margin-top: 0px;">
<li>vktMultiBlockDataSet containing N vtkImageData objects as child blocks.</li><li>vtkMultiBlockDataSet containing 1 vtkMultiPieceDataSet, which contains N vtkImageData objects as child pieces</li></ol>
<div><br>
</div>
<div>The first structure kind of works, but in order to visualize one vtkImageData I need to "Extract Block" and "Resample to Image", which doesn't result in the exact same image when doing volume rendering.</div>
<div>The second structure mixes my vtkImageData into a single data object. I cannot do something like "Extract Piece".</div>
<div><br>
</div>
<div>The main reason I want to have a single data structure containing all my grids is so that I can pass it to my Python CoProcess Catalyst pipeline. The number of grids can vary so I cannot simply hardcode the pipeline for a fixed number of grids.</div>
<div><br>
</div>
<div>If there is a way to make this work, please let me know!</div>
<div><br>
</div>
<div>Best,</div>
