Dear Mitk users,
I am still developping my application using Mitk as a library.
I have a new issue: I use a custom class of data, containing a 3D point
set and a surface. The surface is a cylinder around the 3D points. I
created a new class, inheriting form mitk::Surface. At the beginning,
only the surface was displayed in the multiwidget, I assume because the
SurfaceVtkMapper is used. I started writing a custom mapper for my
custom data, but the 3D points are still not displayed.
My mapper class inherits mitk::SurfaceVtkMapper2D, and has a
mitk::PointSetVtkMapper2D as a protected member.
Its header is as follows:
class NerveDataVtkMapper2D : public mitk::SurfaceVtkMapper2D
{
public:
mitkClassMacro(NerveDataVtkMapper2D, mitk::SurfaceVtkMapper2D)
itkFactorylessNewMacro(Self)
itkCloneMacro(Self)
/// \brief Constructor.
NerveDataVtkMapper2D();
~NerveDataVtkMapper2D();
virtual const NerveData *GetInput() const;
virtual vtkProp *GetVtkProp(mitk::BaseRenderer *renderer)
override;
static void SetDefaultProperties(mitk::DataNode *node,
mitk::BaseRenderer *renderer = NULL, bool overwrite = false);
virtual void Update(mitk::BaseRenderer *renderer) override;
virtual void SetDataNode(mitk::DataNode* dataNode) override;
protected:
mitk::PointSetVtkMapper2D::Pointer _pointSetMapper;
};
and the Update function is:
void NerveDataVtkMapper2D::Update(mitk::BaseRenderer * renderer)
{
// Update control points
_pointSetMapper->Update(renderer);
// Update Surface
mitk::SurfaceVtkMapper2D::Update(renderer);
}
When I try to display the data, only the surface is displayed.
Do you have any idea of what I am missing? I will happily provide more
information about my code if necessary.
