Thanks for your reply.<br>
<br>
Unfortunately i cannot share the dataset. However, the input data only relates to the output data in a way that it provides an upper bound for the output bounds. The actual dimensions and bounds are input by the user and are then processed to extent and spacing
which are used for the output properties.<br>
<br>
I am constructing the grid in the following way: <br>
<br>
this->seedGrid = vtkSmartPointer<vtkImageData>::New();<br>
<br>
int extentSeedGrid[6];<br>
extentSeedGrid[0] = 0;<br>
extentSeedGrid[1] = static_cast<int>(this->dimensionSeedGrid[0])-1;<br>
extentSeedGrid[2] = 0;<br>
extentSeedGrid[3] = static_cast<int>(this->dimensionSeedGrid[1])-1;<br>
extentSeedGrid[4] = 0;<br>
extentSeedGrid[5] = static_cast<int>(this->dimensionSeedGrid[2])-1;<br>
<br>
///Set Size and extent of the seedng grid<br>
seedGrid->SetExtent(extentSeedGrid);<br>
seedGrid->SetOrigin(this->originSeedGrid);<br>
///Calculate and set spacing of the seeding grid<br>
<br>
<br>
this->spacingSeedGrid[0] = this->boundsSeedGrid[0]/static_cast<double>(extentSeedGrid[1]);<br>
this->spacingSeedGrid[1] = this->boundsSeedGrid[1]/static_cast<double>(extentSeedGrid[3]);<br>
this->spacingSeedGrid[2] = this->boundsSeedGrid[2]/static_cast<double>(extentSeedGrid[5]);<br>
this->seedGrid->SetSpacing(this->spacingSeedGrid);<br>
<br>
<br>
<br>
#if VTK_MAJOR_VERSION <= 5<br>
<br>
this->seedGrid->SetNumberOfScalarComponents(1);<br>
this->seedGrid->SetScalarTypeToDouble();<br>
this->seedGrid->AllocateScalars();<br>
<br>
#else<br>
this->seedGrid->AllocateScalars(VTK_DOUBLE,1);<br>
#endif<br>
<br>
<br>
Where dimensionsSeedGrid and boundsSeedGrid are input by the user. <br>
Paraview does show the correct bounds and dimensions within the information tab.
<br>
<br>
I hope this provides useful information to find the solution of my problem<br>
<br>
<br>
Best regards <br>

<p>Dear all,</p>
<p>Within one of my custom filters i am trying to return an uniform grid, i.e. vtkImageData.</p>
<p>When using the filter within paraview the bounds, extent and spacing are detected correctly, meaning they are the same as the input, as intended. However, the outline representation greatly differs from the outline of the input data. I have included pictures
of the surface and point representation of the output. Notice that the "volume" is open on the one side. The outline image shows the outline of the original image, which would be the correct size, while the actual outline is larger than intended. I appreciate
any indication what might be causing this behavior. <br>
