[vtkusers] vtksmartvolumemapper issues

[Maguire, Alister Owen]

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?
