T-Spline surfaces look pixelated in Rhino

[anjahilber]

T-Spline surfaces in rhino look pixelated.
I changed the setting of Meshing from Low to High, but it still looks like the photos in the appendix.
Is it possible that the T-Spline body was not drawn correctly in some places and therefore it looks like this?
or could it be related to a Rhino visualization setting?

Thanks…

Looks like you might be very, very far from the origin…
