Hi I uploaded a cleaned version of the reader without gui component to https://expirebox.com/download/b5db956fb2b0787ac16ef9b42e46698a.html (again 48h available). The GUI has included a timer which polls on the HasNewData() function and if it returns true it forces an update of the request data function. I copied that workflow of the PCLPlugin of Paraview of the Kinect OpenNI Source….. the commented code also displays the *.vti writing....

That's weired, your VTI is correct. And what if you save the output of your filter/reader with ParaView "Save Data"? Is data correctly saved and reloaded correctly?

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.

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(), &oData.imgData[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 1920000 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), by the way: can I disable "MapScalars" by default?
