Hmmm, my problem is not here I think but rather on how to connect both grids by tetrahedra so as to have a multiblock dataset emcompassing the whole 3D area, ie the original low-resolution grid, since the reason I have to face this issue comes from the fact I have run a more accurate simulation on part of the original grid and to do it I have oversampled the grid in a specific zone.<br><br><hr id="stopSpelling">From: gbivins@objectreservoir.com<br>Date: Tue, 17 Nov 2009 15:41:21 -0600<br>Subject: Re: [vtkusers] Joining 2 strutured grids<br>To: stan1313@hotmail.fr<br>CC: vtkusers@vtk.org<br><br><br>Hi "Fred Fred",<div>One way would be to create <a href="http://www.vtk.org/doc/release/5.4/html/a00854.html">ImplicitDataSets</a> for each of your structured grids and then use the <a href="http://www.vtk.org/doc/release/5.4/html/a00853.html">ImplicitBoolean</a> to combine the two datasets into one.</div>

Hello,<br>I have 2 structured grids of different granularities, one of them being partially included in the other. When I try to render these grids, there is of course an overlapping region in which the visualization is not nice. So I can just visualize the non overlapping regions of both grids but this yields to a gap of course. My problem nom is: how to join these 2 grids, ie how to tetrahedralize the gap between them? I need some tetra Delaunay. I suppose this problem has been addressed by several vtk or PV users and may be I could get some hints here.<br>
Thanks in advance for your help.<br><div class="ecxhm"><br><br> <br><hr>PC, téléphones portables, souris hi-tech. à gagner grâce à Hotmail ! <a href="http://www.hotmailmagicmoment.com">C'est ici !</a></div>
