[vtkusers] vtksmartvolumemapper issues

 Alister,
 
Thanks for your help I managed to get the code working now It was a missing autoinit line.
 
I ended up needing to add
#define vtkRenderingVolume_AUTOINIT 1(vtkRenderingVolumeOpenGL2)
 
at the top of my code
-Thanks,
Mark

  Are you including the following two lines in your .C file?
 
 #include <vtkAutoInit.h>
 VTK_MODULE_INIT(vtkRenderingVolumeOpenGL2);
 
 I'm not sure if this is the root of your issue, but I had run into problems while working with vtkSmartVolumeMapper a while back, and I ended up discovering that these two lines were needed for it to be used properly.
 
 You can find more info about it here

 Best,

Hello all,
 
 
 
I am updating some old vtk 6.3 code to vtk 8.1, Currently the older code uses vtksmartvolumemapper, I am running into a run time error with a new smart pointer. 
 
 
 
my code:
 
 
 
#include <vtkSmartVolumeMapper.h>
 
..
 
..
 
..
 
vtkSmartPointer<vtkSmartVolumeMapper> vMapper  = vtkSmartPointer<vtkSmartVolumeMapper>::New();    < = this breaks with unhandled exception at (vtkRenderingVolume-8.1.dll) Access violation reading location 0x0000000000000000
 
 
 
 
 
 
 
The code compiles, but I hit this run time exception on execution. I don't believe the smartvolumemapper has been deprecated, does anyone have any idea of what I am doing wrong?
