Hi,<div><br></div><div>I have several vtkUnstructuredGrid(s) that I read in from disk, they are separate components of a large model. For various reasons I'd like to be able to keep them separate but, for the majority of my program proxy them all by one interface as one single "glued" object of that type, in this case a single <span style="background-color:rgb(255,255,0)">vtkUnstructuredGrid</span>. For example, if I have a file that I read in for a nut, and a second file for a bolt, I would like them to remain separate, but pass around an object that allowed me to do, say GetPoints(), on a single <span style="background-color:rgb(255,255,0)">vtkUnstructuredGrid object </span>that gave me all the points in both the nut and bolt meshes. Actually, I would like to in a sense have the whole interface for vtkUnstructuredGrid and anything beneath it, but behind hold a vector of vtkUnstructuredGrids, or indeed another type, vtkpolydata for example. </div>
<div><br></div><div>Is this possible? I do not think the vtkMultiBlock... is what I want. Alternatively, if this is not possible, is there anything that will allow me to "add" using operator+ for example the nut and bolt together to get a single mesh back. This is not really what I want but would suffice.</div>
<div><br></div><div>I would much prefer the former, but the latter is fine if the former is not possible.</div><div><br></div><div>Any help much appreciated. Again, primary importance is one interface that under the hood is a vector of said types, where that type need not be a vtkunstructuredGrid, but that would be ideal initially....</div>
<div><br></div><div>Cheers again,</div><div>Andy<br>
