Hello

I’m working with VTK for volume rendering but encountering unexpected artifacts when visualizing medical imaging data. Specifically, I notice strange flickering or ghosting effects when rotating the volume, even with proper shading and transfer functions applied. 🙃

Adjusting sampling distance and interpolation methods improves it slightly, but the issue persists. 🤔

Has anyone else faced similar rendering artifacts in VTK? Could this be related to [devops](https://www.igmguru.com/cloud-computing/devops-certification-training) GPU driver compatibility, or is there an optimal setting to smooth out these visual glitches? Any insights or debugging techniques would be greatly appreciated! 🙂

Thank you!!
