Hi,
I was able to enable the vtkSplineFilter in ParaView-3.7 with the
attached ServerManager XML. But with the current 3.9, I am having a
segfault after the filter updates. Here is the WinXP32 call stack
after the segfault :

Hi Biddiscombe,
I do a similar thing. But I use a Qt thread instead of a timer. The thread
controls the entire progress. I define a iteration steps in the thread,
e.g.,1024. In each iteration, the thread triggers the slot accept() method
(in ParaView3/Qt/Components/pqObjectInspectorWidget), in
Hi again !
I tried to replace the SplineFilter with a ProgrammableFilter
containing the following script :
input = self.GetInput()
splineFilter = vtk.vtkSplineFilter()
splineFilter.SetInput( input )
splineFilter.SetSubdivideToLength()
splineFilter.SetLength( 1 )
splineFilter.Update( )
Hi,
The error related to command prompt was removed.
But now during building I am getting 80% of the projects as failed with
many types of errors.
Please could you give me the exact link (other than the wiki page for
build and install) to build it from scratch again.
The specifications of my
The Wiki page pretty much covers all that's necessary to build the
software. You'll have to be a bit more elaborate than many types of
errors before we can offer some concrete help. Are you using Qt
binaries downloaded from Nokia's website? As mentioned on their
download page, Nokia's binaries are
What is the standard way to represent image data in VTK/ParaView, where the
image data is intended to represent finite sized voxels? Here the 3D image
data represent values at the centre of voxels (or presumably some sort of
weighted value centred on the voxel centre).
This may seem like a
Hello,
in vtkImageData, Dimension is the number of points along each axis,
not the number of cells along each axis. If you want one voxel, then
you need 2x2x2 points.
Note that using GetDimension() is OK but SetDimension() is only here
for backward compatibility, use SetExtent() instead:
Hi,
I have seen this error mostly relating to a plugin being loaded on the
client side but not the server side. It looks like
vtk1DTransferFunctionFilter, is part of a PointSprite plugin. You could
check the tools-plugin manager dialog to see if the client and server
have the same plugins
Hello to all,
thanks for your help. Oh, I think I got it...

Thanks Eric, all,
but this does not seem to work at all. My loop looks something like this:

output = self.GetOutputDataObject(0)
if input.IsA(vtkMultiBlockDataSet):

Francois,
Thank you for the reply.
Using 2x2x2 points for one voxel is fine in principle. The difficulty is, you
can't really conveniently (as far as I can tell) use a vtkImageData object for
this purpose. Because now of course our scalar image data needs to be
associated with cells, not to
Hi Eric,
Because now of course our scalar image data needs to be associated with cells,
not to points. But vtkImageData in many cases only deals with the scalar data
attached to the PointData.
Could you use the concept of a dual grid? In other words make your vis
grid node centered with the

Burlen,
I assume by dual grid you mean creating two vtkImageData objects, which both
contain pointers (properly registered and reference counted) to the same
vtkDataArray object, but in one case, as the Scalars for the CellData, and in
the other case as the Scalars for the PointsData. This
Hello,
I have downloaded the 3.8 release source from the download page and I try to
compile it on Mac OS X Leopard, using the classic cmake porcedure that has been
successful with the 3.6.2 but I get a surprising error:
