Re: [Paraview] [Paraview-developers] vtkImageData Plugin, vtkImageData not rendered
I now have it (but don’t know why, an explanation would be great), my solution
was deleting RequestData and using same pipeline as copied from
vtkJPEGReader/vtkImageReader2 with request information:
int vtkROSImageSource::RequestInformation(
vtkInformation * vtkNotUsed(request),
vtkInformationVector** vtkNotUsed(inputVector),
vtkInformationVector * outputVector)
{
vtkSmartPointer latest = this->m_poInternal->GetLatestImageData();
if (latest)
{
this->DataExtent[0] = oLatest->GetExtent()[0];
this->DataExtent[1] = oLatest->GetExtent()[1];
this->DataExtent[2] = oLatest->GetExtent()[2];
this->DataExtent[3] = oLatest->GetExtent()[3];
this->DataExtent[4] = oLatest->GetExtent()[4];
this->DataExtent[5] = oLatest->GetExtent()[5];
this->SetDataScalarType(latest ->GetScalarType());
this->SetNumberOfScalarComponents(latest
->GetNumberOfScalarComponents());
// get the info objects
vtkInformation* outInfo = outputVector->GetInformationObject(0);
outInfo->Set(vtkStreamingDemandDrivenPipeline::WHOLE_EXTENT(),
this->DataExtent, 6);
outInfo->Set(vtkDataObject::SPACING(), this->DataSpacing, 3);
outInfo->Set(vtkDataObject::ORIGIN(), this->DataOrigin, 3);
vtkDataObject::SetPointDataActiveScalarInfo(outInfo,
this->DataScalarType,
this->NumberOfScalarComponents);
outInfo->Set(CAN_PRODUCE_SUB_EXTENT(), 1);
}
return 1;
}
void vtkROSImageSource::ExecuteDataWithInformation(vtkDataObject *output,
vtkInformation *outInfo)
{
vtkImageData *data = this->AllocateOutputData(output, outInfo);
vtkSmartPointer latest =
this->m_poInternal->GetLatestImageData();
if(latest)
{
data->ShallowCopy(latest);
}
}
The only thing which is bad is that paraview does use "SolidColor" as default
with "Outline" Representation. I have to switch to my scalar name and "Slice"
representation manually, any hints how to do that automatically? Would also
like to turn off "MapScalars" by default...

Betreff: AW: [Paraview-developers] [Paraview] vtkImageData Plugin, vtkImageData
not rendered
Good idea, I made some tests:
if (this->HasNewData())
{
this->OLatest = this->m_poInternal->GetLatestImageData();
}
else
{
vtkErrorMacro(“You should never came here”); }
I also tested to set a member variable vtkSmartPointer
myTempImage; to the class (like you mentioned) and store it everytime so that
output gets always ShallowCopied regardless to the HasNewData, but no effect.
The HasNewData is always true because I call this function from my GUI panel
and only force an update if that function returns true, so it would be strange
if that would not work…..
I have the exact same workflow in my vtkPolyData source which works perfectly…
I really don’t know why this does not work…. I copied the workflow from the
PointCloud plugin…. (OpenNISource)
I also made now a minimalistic test and changed my requestdata function to:
vtkInformation *outInfo = outputVector->GetInformationObject(0);
vtkImageData *output = vtkImageData::SafeDownCast(outInfo
->Get(vtkDataObject::DATA_OBJECT()));
vtkSmartPointer imageData =
vtkSmartPointer::New();
imageData ->SetDimensions(10, 10, 1);
imageData ->AllocateScalars(VTK_FLOAT, 1);
memset(imageData ->GetScalarPointer(), 0, 10*10*sizeof(float));
output ->ShallowCopy(imageData);
same behaviour….
Another failed try:
output ->SetDimensions(10, 10, 1);
output ->AllocateScalars(VTK_FLOAT, 1);
memset(output ->GetScalarPointer(), 0, 10 * 10 * sizeof(float));
By the way: why dows paraview say that images are rectilinear grid's? My output
is a vtkImageData which does not seem to be inherited from rectilinear grid
also when I load images normally into paraview I get rectilinear grids as
output. should I program a rectilinear grid output filter?

Gerald,
I think there is the problem with this:
if (!this->HasNewData())
return 1;
It means that most of the time, the filter will return an empty output.
Instead, you should cache (retain a pointer off oLatest as member variable) the
last image and ShallowCopy it to the output in this case.

Could you share the code of your reader? If you prefer you can remove all
specific stuff and keep only VTK related stuff.
I would like to see how exactly you fetch the output grid to fill and how your
filter defines its output.

OK. That's weired, your VTI is correct.
And what if you save the output of your filter/reader with ParaView "Save

Hmm sorry if I had took a closer look I would have seen that AllocateScalars
set a default name "ImageScalars" to the scalar array.
Then don't know what you did but the print says that the name of your array is
"21745593" which is quite strange. Is it what you did?
Could you write your "output" image data to a .VTI file using a
vtkXMLImageDataWriter after initializing it in your RequestData
function and see if you can load in with PV and view it? Share it if you can't.

ParaView won't make visible arrays which don't have a name.
Example:
output->GetPointData()->GetScalars()->SetName("values");

Hi
I programmed successfully a plugin source wich generates a vtkImageData output
and made it the same way as on my 3d cloud plugins of vtkPolyData. The source
is inherited from vtkImageAlgorithm and only contains one output with unsigned
char array and one component.
In the request data function of the filter I currently have a very dummy:
output->SetDimensions(oData.imgSizeX, oData.imgSizeY, 1);
output ->AllocateScalars(VTK_UNSIGNED_CHAR, 1);
memcpy(output ->GetScalarPointer(), [0], oData.imgSizeX*
oData.imgSizeY*sizeof(unsigned char));
in paraview I see in the information tab that I have an uniform rectilinear
grid with 1917201 cells and 192 points (image is 1600*1200px). In data
Arrays I get an "ImageScalars" of unsigned char and a correct range of my
memcopy data (my min max range is not 0,255 so data seems to be there)...
the problem is that I cannot see anything in the render view, any suggestions
what I am making wrong? I tested all representation (slice, surface, outline,
on Solid Color and on my array), never see anything.
I also compared the Information tab on a loaded jpeg image and cannot see any
difference (which is rendered in render view except the Array's string name),
