Hi Miri,
the code looks fine to me. Although, you did not show how you created the
lookup table and how you set the scalars. Here is one example how it worked for
me:
Assume your table range is from 0 to 10, your mesh is contained in the
vtkPolyData polyData, and your scalars are stored in vtkDoubleArray* scalars.
// set scalars to poly data
polyData->GetPointData()->SetScalars(scalars);
mitk::Surface::Pointer surface = mitk::Surface::New();
surface->SetVtkPolyData(polyData);
// create vtk lookup table
vtkLookupTable* vtkLut = vtkLookupTable::New();
vtkLut->SetTableRange(0.0,10.0);
vtkLut->Build();
// create mitk lookup table
mitk::LookupTable::Pointer mitkLut = mitk::LookupTable::New();
mitkLut->SetVtkLookupTable(vtkLut);
// create lookup table property
mitk::LookupTableProperty::Pointer mitkLutProp =
mitk::LookupTableProperty::New(mitkLut);
// create node and add properties
mitk::DataNode::Pointer node = mitk::DataNode::New();
node->SetData(surface);
node->SetProperty("LookupTable",mitkLutProp);
node->SetBoolProperty("scalar visibility",true);
node->SetFloatProperty("ScalarsRangeMaximum",10);
node->SetBoolProperty("color mode",true);
node->Update();

Alex

Betreff: Re: [mitk-users] Visualization of a colored surface
Hi Alexander,
Thank you for the helpful idea.
(isn't this the right command- with argument two? :
Node->SetProperty("LookupTable",LookupTableProp);)
Anyway, attached the code's snippet which still not visualizes the colored
surface on the 2d planes.
- any suggestions?
mitk::LookupTableProperty::Pointer myFilter::getLookUpTableProp()
{
mitk::LookupTable::Pointer mitk_lut = mitk::LookupTable::New();
mitk_lut->SetVtkLookupTable(m_vtk_lut);
mitk::LookupTableProperty::Pointer LookupTableProp =
mitk::LookupTableProperty::New();
LookupTableProp->SetLookupTable(mitk_lut);
return LookupTableProp;
}
mitk::LookupTableProperty::Pointer LookupTableProp =
mitk::LookupTableProperty::New();
LookupTableProp = myFilter->getLookUpTableProp();
mitk::DataNode::Pointer Node = mitk::DataNode::New();
Node->SetData( Surface );
Node->SetProperty("scalar visibility", mitk::BoolProperty::New(true));
Node->SetProperty("color mode", mitk::BoolProperty::New(true));
Node->SetProperty("material.specularCoefficient",
mitk::FloatProperty::New(0.5));
Node->SetProperty("LookupTable",LookupTableProp);
Node->SetName(scalpNodeName.str());
Node->Update();

Hi Miri,
you could also try to add a LookupTableProperty to your surface node you
want to have colored. That will allow you to specify the range of colors
your scalars will be visualized. That worked for my case also for the 2D
planes. What you have to do is:
- Create your specific lookup table mitk::LookupTable::Pointer lut
- Set the lookup table as a property to your node:
node->SetProperty("LookupTable",lut);
Regards,
Alex
