[Paraview] Problems writing binary vtu file
Dear Paraview, I tried to extend my VTU writer to write into binary format. I have tried either writing floats using Float32 format and doubles using Float64 format, both fail the same way. I write into binary by using file.write( (char*) , sizeof(BinaryType)); In both cases, Paraview complains that there is an invalid token immediately at the beginning of binary output within the first DataArray clause. Could someone please hint me as of what I am doing wrong.

[Paraview] Problems writing an .vtu file
Hello everybody, I've been trying to write a c++ function to convert my data into .vtu files. Unfortunately, paraview isn't able to read my .vtu files. I get the following error-message: ERROR: In /home/zam/domini/paraview/ParaView3src/VTK/Filtering/vtkExecutive.cxx, line 757 vtkCompositeDataPipeline (0x8cf34b0): Algorithm vtkXMLUnstructuredGridReader(0x8d915d0) returned failure for request: vtkInformation (0x90c34e8) Debug: Off Modified Time: 383066 Reference Count: 1 Registered Events: (none) Request: REQUEST_INFORMATION FORWARD_DIRECTION: 0 ALGORITHM_AFTER_FORWARD: 1 I'm obviously doing something wrong... can anyone help?
