[vtkusers] Issues with using vtkSmartVolumeMapper.

[vipulraikar]

Hello Everybody,

I am currently working on some volume rendering and using vtk.6.1.0. I am
aware that since vtk 6.0 the need to init factories for modules. I have done
the same. 
I am having issues when I am trying to create a new instance of
vtkSmartVolumeMapper. It returns the following error:

Generic Warning: In
V:\Research\code\libsrc\VTK-6.1.0\Rendering\Volume\vtkRayCastImageDisplayHelper.cxx,
line 20
Error: no override found for 'vtkRayCastImageDisplayHelper'

On further investigation I gather that this call is returning a NULL.

this->ImageDisplayHelper  = vtkRayCastImageDisplayHelper::New(); (in
vtkFixedPointVolumeRayCastMapper.cxx, Ln 716)

Am I missing something? Is there any other module that needs to be
initialized? (other than the following)

VTK_MODULE_INIT(vtkRenderingOpenGL);
VTK_MODULE_INIT(vtkInteractionStyle);
VTK_MODULE_INIT(vtkRenderingFreeType);
VTK_MODULE_INIT(vtkRenderingFreeTypeOpenGL);

Any help/direction/thoughts would be greatly appreciated. :)

best regards,

Vipul
