[vtkusers] Trying out the new vtkGPUVolumeRayCastMapper null pointer

[Doug Hoppes]

Hi all,

                I got the latest nightly build and trying out the new vtkGPUVolumeRayCastMapper. The build works fine but when I try to call

m_pMapper = vtkSmartPointer<vtkSmartVolumeMapper>::New();

I get an immediate crash.

Inside of the vtk code, the crash happens when it tries to instantiate  the GPUMapper and then set the MaxMemoryInBytes, it crashes because the GPUMapper instantiation is null (vtkSmartVolumeMapper.cxx line 66).

Any idea why?  For my vtk library builds, I made sure that the Module_vtkRenderingVolumeOpenGLNew = 1).

Doug
