I am reading a data file that is a has dimensions 189 x 201 x 1.
During the RequestInformation I set the WHOLE_EXTENT to:
int NumEvenCols = 189;
int NumRows = 201;
extents[0] = 0;
extents[1] = NumEvenCols-1;
extents[2] = 0;
extents[3] = NumRows-1;
extents[4] = 0;
extents[5] = 0;
outInfo->Set( vtkStreamingDemandDrivenPipeline::WHOLE_EXTENT(),
extents,
6 );
Then in the RequestData() method I initialize each vtkImageData
object
(there are 6 output ports):
//------------------
output->SetScalarTypeToFloat();
int xDim=NumEvenCols;
int yDim=NumRows;
int zDim=1;
output->SetDimensions( xDim, yDim, zDim );
output->SetNumberOfScalarComponents( 1 );
output->AllocateScalars();
output->GetPointData()->GetScalars()->SetName("Data");
output->GetPointData()->SetActiveScalars("Data");
//------------------
The data seems to be read OK but when the GUI tries to finish up
the
display I get an "Unhandled exception at 0x01462f3f

paraview.exe: 0xC0000005: Access violation writing location

Now, what is odd is that if I set the Z Extent from 0 to 1, then
I get
a rendering except that the rendering is wrong because there are
now 2
slices in the z direction. So what am I doing wrong? I can send
code
and data file if necessary.
