<div dir="ltr"><div>Hi All,</div>
<div> </div>
<div>I hope somebody will answer me this time :-)</div>
<div>actualy, my question is very simple:</div>
<div> </div>
<div>In order to divide my polyData- I simply divided it to buckets such that each bucket will contain X number of cells in this way:</div>
<div> </div>
<div><br> unsigned int cell_num = poly->GetNumberOfCells();</div>
<div> </div>
<div>// building vtkCellLocator<br> vtkSmartPointer<vtkCellLocator> cellLocator = vtkSmartPointer<vtkCellLocator>::New();<br> cellLocator->SetDataSet(poly);<br> cellLocator->BuildLocator();<br> cellLocator->SetNumberOfCellsPerBucket(cell_num/numOfRequiredRegions);<br>
cellLocator->Update();</div>
<div> </div>
<div>//build a list of indexes for each region<br> vtkSmartPointer<vtkIdList> listOfIndexesInBucket = vtkSmartPointer<vtkIdList>::New(); </div>
<div> vtkIdType curIdx;</div>
<div> </div>
<div> //go over each bucket</div>
<div> for(int i=1; i<numOfRequiredRegions; i++)</div>
<div> {<br> <strong>listOfIndexesInBucket = cellLocator->GetCells(i);</strong></div>
<div> for(vtkIdType id=1; id<cell_num; id++) //go over each cell in bucket<br> curIdx = listOfIndexesInBucket->GetId(id); //get the index in each cell</div>
<div> }</div>
<div> </div>
<div> </div>
<div>Unfortunately, there is a RT error in the marked line above and the folowing code + massage are represented the error:</div>
<div> </div>
<div>unhandled exeption acces violaion reading location ...</div>
<div>and the code is:</div>
<div> </div>
<div>void vtkSmartPointerBase::Register()<br>{<br> // Add a reference only if the object is not NULL.<br> if(this->Object)<br> {<br> this->Object->Register(0);<br> }<br>}<br></div>
<div> </div>
<div>Any Idea ?</div>
<div> </div>
<div> </div>
<div>Thanks.</div>

<div dir="ltr">Hi all,<br><br>I have a vtkPolyData and would like to:<br>1. divide it to regions/areas/pieces<br>2. get the indexes/cells/array from that division to further processing<br><br>Visually, I'd like to get <a href="http://www.vtk.org/Wiki/VTK/Examples/Cxx/Meshes/OBBDicer" target="_blank">this</a> division BUT to use the indexes that this division returns.<br>
(if you look at the attached link, I'd like to get the points that each piece has)<br>I know OBBDicer won't return the required data, but which can?<br><br>ANY help, I'm lost ...<br>Thanks.<br></div></div><br>
