SplineClosed
is an option for B-spline functions and graphics primitives that specifies whether spline curves or surfaces should be closed.
Details

- For curves, the setting SplineClosed->True makes the first and last points be connected smoothly.
- For higher-dimension surfaces and manifolds, SplineClosed->True makes all boundaries be connected smoothly.
- With the setting SplineClosed->True, all boundaries are connected smoothly.
- With the setting SplineClosed->{c1,c2,…}, the boundaries are connected in directions i for which ci is True.
