Hello MITK community,
I want to show a vtkUnstructuredGrid with scalars in the MITK application and
have problems with showing the color coded scalars and to make the data node
again visible after make it unvisible using the check box of the data manager
to show and hide nodes.
Here is the code:
void QmitkStentBundleView::makeFEresult(QString filename, QString nodename)
{
/********************************************************
* create a mitk::DataNode
* the data is a unstructured Grid of the class FEresult
* the FEresult is called with "filename"
* the name of the node is "nodename"
* at the end a global reinit ist called to show the new node
*********************************************************/
//FEresult builds a vtkUnstructuredGrid with scalar values out of an external
data file
FEresult* result = new FEresult(file); //NR Übergabe ifstream
result->uGrid->SetPoints(result->nodeCoordinates);
result->uGrid->GetPointData()->SetScalars(result->scalars);
result->buildScalars();
result->nodeCoordinates->Delete();
mitk::UnstructuredGrid::Pointer grid = mitk::UnstructuredGrid::New();
grid->SetVtkUnstructuredGrid(result->uGrid);
//Generate data node
mitk::DataNode::Pointer node = mitk::DataNode::New();
node->SetName(nodename.toStdString().c_str());
node->SetOpacity(1.0f);
//Node properties
mitk::LookupTable::Pointer lookupTable = mitk::LookupTable::New();
lookupTable->SetVtkLookupTable(result->lut);
node->SetBoolProperty("scalar visibility", true);
//scalarBar???
node->SetBoolProperty("color mode", true);
node->SetFloatProperty("ScalarsRangeMaximum",
(float)*result->uGrid->GetScalarRange());
node->SetProperty("outline polygons", mitk::BoolProperty::New(false));
node->SetBoolProperty("show points", true);
node->SetBoolProperty("show contour", false);
node->Update();
//Attach grid + mapper to data node
node->SetData(grid);
//data storage
mitk::DataStorage::Pointer m_DataStorage = this->GetDataStorage();
m_DataStorage->Add(node);
//global reinit:
mitk::RenderingManager::GetInstance()->InitializeViews(
m_DataStorage->ComputeBoundingGeometry3D(m_DataStorage->GetAll()));
return;
}
Thanks in advance.
Best regards,
Sandra
