Hello Steiner <span dir="ltr">，</span>thank you <span dir="ltr"></span>very much at first！ If my undestanding is right，your code may be very suitable to catch exception! I will learn it !<br>However, the key problem of my app may not the bug, but how to manage memory more efficiently !<br>

<b>Betreff:</b> [vtkusers] memory allocate problem of multi-iso
reconstruction(large data)</span></p>
</div><div><div></div><div class="h5">
<p class="MsoNormal"> </p>
<p class="MsoNormal">Hello all in mailing list,<br>
<br>
The develop tool of my application are VC6.0 + vtk5.1. And I'd
appreciate any advice to help me to soleve the problem.<br>
<br>
The state of mine is that when i use MC to reconstruct , and select one single
contour value, the number of image is 200(bmp: 329*354). of coucse , the
app is sucessfully executing!<br>
However, i'd like to reconstuct multi-isosurface. In addition, i hope the app
can control property of each isosurface(vtkactor*). So I use multi-pipeline to
reconstruct,each actor has private pipeline, but the result is error when there
are many contour values ,for example the number of contour values is 4 , the
main code and relevant information as follows:<br>
<br>
// the data set is bmp: 329*354*350<br>
<br>
std::vector<vtkMarchingCubes*> vskinExtractor;<br>
std::vector<vtkDecimatePro*> vdeci;//<br>
std::vector<vtkSmoothPolyDataFilter*> vsmoother;//<br>
std::vector<vtkPolyDataNormals*> vskinNormal;//<br>
std::vector<vtkPolyDataMapper*> vskinMapper;//<br>
std::vector<vtkActor*> vskin;<br>
<br>
//y is the number of the scalar value, here is 4<br>
for (size_t numIndex = 0; numIndex < y; numIndex++)<br>
{<br>
vskinExtractor.push_back(vtkMarchingCubes::New());<br>
vskinExtractor[numIndex]->SetInputConnection(m_read->GetOutputPort());<br>
vskinExtractor[numIndex]->SetValue(numIndex, vYuzhi[numIndex]);<br>
<br>
vdeci.push_back(vtkDecimatePro::New());<br>
vdeci[numIndex]->SetInputConnection(vskinExtractor[numIndex]->GetOutputPort());//<br>
vdeci[numIndex]->SetTargetReduction(0.5);//<br>
vdeci[numIndex]->PreserveTopologyOn();//<br>
<br>
vsmoother.push_back(vtkSmoothPolyDataFilter::New());<br>
vsmoother[numIndex]->SetInputConnection(vdeci[numIndex]->GetOutputPort());//<br>
vsmoother[numIndex]->SetNumberOfIterations(800);//Specify the number of
iterations for Laplacian smoothing<br>
<br>
vskinNormal.push_back(vtkPolyDataNormals::New());<br>
vskinNormal[numIndex]->SetInputConnection(vsmoother[numIndex]->GetOutputPort());//<br>
vskinNormal[numIndex]->SetFeatureAngle(60.0);//<br>
<br>
vskinMapper.push_back(vtkPolyDataMapper::New());<br>
vskinMapper[numIndex]->SetInputConnection(vskinNormal[numIndex]->GetOutputPort());<br>
vskinMapper[numIndex]->ScalarVisibilityOff();<br>
<br>
vskin.push_back(vtkActor::New());<br>
vskin[numIndex]->SetMapper(vskinMapper[numIndex]);
<br>
}<br>
<br>
<br>
After the app executing dozens of minutes, the vtkOutputWindow
output error messages:<br>
Error:in c:\vtk5.0\vtk\common\vtkDataArrayTemplate.cxx line 255<br>
vtkIdTypeArray(0x...):unable to allocate 62300005 elements of size 2<br>
<br>
In my opinion,may be the reason is that data is too large or there
are generating too many meshes while MC extracting isosurface, but
i do not know how to solve it!<br>
I alse lookup information in "VTK FAQ" in KitWare web, and the
solution can't fit my problem. Thanks for any help!!<br clear="all">
