Volumetric rendering artefacts

Support

Hi Guys,
I am new to VTK and i am having some issues related to volumetric rendering using the vtkGPUVolumeRayCastMapper class. It works fine but when the data is moving or rotating, it shows some artefacts on the volumic. I would like to have help about this.
Thank you.

The ray sampling distance is reduced automatically during interaction in order to maintain a certain frame rate. To disable this you can call AutoAdjustSampleDistancesOff() on the mapper.

See https://vtk.org/doc/nightly/html/classvtkGPUVolumeRayCastMapper.html#a1efa0bc84b54f52564153fb22ae4b1fa
