Hi,
I'm new to using ITK, and I'm trying to execute the following code.
typedef double VoxelType;
const unsigned int VolumeDimension = 3;
typedef itk::Image< VoxelType, VolumeDimension >
ImageTypeVolume;
typedef itk::RayCastInterpolateImageFunction< ImageTypeVolume, double >
RayCastType;
RayCastType::Pointer RayCaster = RayCastType::New();
However, I get the following error from MVC++ 6.0 that says
.itkRayCastInterpolateImageFunction.txx(595) : error C2440:
'initializing' : cannot convert from 'const class itk::Vector<double,3>'
to 'const double *
'
No user-defined-conversion operator available that can perform
this conversion, or the operator cannot be called
.\..\..\Insight\InsightToolkit-1.6.0\Code\Common\itkImportImageContainer
.h(87) : while compiling class-template member function 'bool __thiscall
itk::RayCastInterpolateImageFunction<class
itk::Image<double,3>,double>::SetRay(class itk::Point
<double,3>,class itk::Vector<double,3>) const'
So, what exactly am I doing wrong?
Thanks for your help!
-Jared
