<div>Dear list,</div>
<div><br>
</div>
<div>I would like to generate some AMR data structures from custom data and filters, but I’m having trouble locating information about the format/relationships of AMR blocks. The wiki contains old outdated references to the heirarchicalbox structures and not
to the overlapping and non overlapping AMR formats.</div>
<div><br>
</div>
<div>Specifically, I’d like to know if each level of AMR boxes must always have a fixed refinement level wrt to the level above, or whether I can refine arbitrarily (i.e. Have a root box of resolution x and sub boxes with different subdivision ratios at the
same level). Also, the overlapping AMR dataset examples I’ve looked at seem to use an oct tree style decomposition where each node must be subdivided along mid planes, can I use a pure BSPtree where every node is subdivided along any axis at any point on the
axis and still maintain a non overlapping amr dataset?</div>
<div><br>
</div>
<div>The vtkAMRInformation documentation consists only of </div>
<div><br>
</div>
<blockquote style="margin:0 0 0 40px; border:none; padding:0px;">
<div>Refinement ratio between AMR levels</div>
<div>Grid spacing for each level</div>
<div>The file block index for each block</div>
<div>parent child information, if requested</div>
</blockquote>
<div><br>
</div>
<div>But does the refinement ratio have to be constant for each level?</div>
<div>Most of the paraview filters appear to be greyed out for vtkNonOverlappingAMR data, whereas the Overlapping appears to have support for certain operations like contouring and slicing – is it the case that only nonoverlapping datasets are supported for
these operations. </div>

<div>If there is detailed info anywhere, could someone please send me a link.</div>

<div>Thanks</div>
