Id like to understand why visualization performance are so poor after clipping (and not after slicing)

Have you heard about a similar issue? I can send some video capture if you want me to

Thank you

Regards

Richard

This is just a guess, but my guess is you have structured data. Clipping will create unstructured meshes. This could make your dataset significantly larger in memory.
