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 //\//\CMakeExternals\Source\VTK\Rendering\vtkOpenGLTexture.cxx,
line 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
