I am trying to use the vtkUnstructuredGridVolumeRayCastMapper in a C++
program to visualize some scalar pointdata. Everytime i call
RenderWindow->Render(); I get an NullException Error. I think it has
something to do with a missing VTK_MODULE_INIT(XXX) since I am not using
Cmake, but i cant find the right macro.

Thanks for the help
