mitk::Surface objects can be visualized directly in MITK, just like any
other mitk::BaseData subclass. Just put it in a mitk::DataNode and add
it to your mitk::DataStorage.

Hi Miklos,
My Exception is:
"..\..\..\CMakeExternals\Source\ITK\Code\Common\itkProcessObject.cxx:981:
itk::ERROR: myModule:(18F41FB8): At least 1 inputs are required but
only 0 are specified"
In the output from Debug of visual studio:
ERROR: In
//\//\CMakeExternals\Source\VTK\Rendering\vtkPolyDataMapper.cxx, line
60 vtkPaintPolyDataMapper (18F4D168) : Mapper has no input
ERROR: In

196 vtkOpenGLTexture (188432F0): No scalar value found for texture input!
what might be the reason for that run time error?
* another conversion question which can save my time: I have a pointer
to a mitk::surface data and would like to view that surface on mitk. I
might need to convert that surface to an mitk::image. how should I do
this?
Thanks,
Miri

Hi Miri,
in your original e-mail there was this line:
itk::Image < ImageType > ::Pointer itkImage_1;
now there is these lines:
typedef unsigned short InputPixelType;
typedef itk::Image < InputPixelType, 3 > InputImageType;
itk::Image< InputPixelType, 3>::Pointer itkImage_1;
These are different. In the first case you have a 2D image, in the
second case 3D.
If the exception is thrown by the Update() function, it means that
it is thrown by the filter's GenerateData function (or from its
call chain). So, I still think that there is a type mismatch
during the cast.
I suggest to put the Update call into an exception handler, catch
itk::ExceptionObject, and print its message. (As I remember, it is
the what() function that tells it to you.)
Best,
Miklos

Thank you for tying to help me.
Casting to the exact input image type is what I tryied to
implement (after checking it with the debugger).
Actually, I ran it again with these commands, but received the
mentioned error.
typedef unsigned short InputPixelType;
typedef itk::Image < InputPixelType, 3 >
InputImageType;
itk::Image< InputPixelType, 3>::Pointer itkImage_1;
- I'd like to mention again that the error accepted in the
following command:
myModulePointer->Update(); // a command at the file:
MyPlugInView.cpp
- My application was generated by the CTK's generator and I
just changed that application in order to get a multiple
number of input images (instead of one input image, as the
generator implemented).

Hi,
are these 2D images?
The itk::Image template class expects two parameters, the
pixel type and the dimension. For the dimension there is a
default value that is 2. That's why your code does not
cause compile error.
However, you must cast the mitk::Image into exactly the
same kind of itk::Image. If you have a 3D mitk::Image, you
cannot cast it into a 2D itk image. Even the pixel types
must be the same.
In your code:
itk::Image < ImageType > ::Pointer itkImage_1;
The ImageType name is rather misleading, since a primitive
type should be there, typically.
Best,
Miklos

Hi everyone,
I manipulated the ability to select and manipulate
four 3D input images from a known type (all of them
have the same type). I mean that the user has to pick
four images on mitk platform and run my module.
But it returns a run-time error which described below.
That run time returned after the command:
myModulePointer->Update();
In addition below is my code, please help me to figure
it out. It's just my first time to manipulate things
like that ...
