In volume rendering, how to set the rendering result to not blur when rotating the camera

[estan (Elvis Stansvik)]

I think you can call AutoAdjustSampleDistancesOff() on the mapper to turn off the automatic adjustment of raycasting sampling distance, then either call LockSampleDistanceToInputSpacingOn() to lock the sampling distance to the input data spacing, or set the sampling distance manually with SetSampleDistance(…).
