SubD.NurbsSurfaceType

SubD.NurbsSurfaceType enum

ON_SubD::NurbsSurfaceType specifies what type of NURBS surfaces are returned by ON_SubD.GetSurfaceNurbsFragments()

Derived Classes:

Namespace: Rhino.Geometry
SubD.NurbsSurfaceType: references

Values (5)

Unset = 0

Not a valid type. Used to indicate the type has not been set and to encourage developers to explicitly specify a type. When in doubt, specify NurbsSurfaceType::Large.

Large = 1

Onee NURBS surface will be generated for each SubD quad. N NURBS surfaces will be generated for each SubD N-gon (N = 3, 5 or more). ON_Brepface may cover multiple Near extraordinary vertices, the surfaces may have lots of knots.

Medium = 2

NURBS surfaces will be as large as possible without the addition of extra knots. Near extraordinary vertices, the surfaces may have lots of knots. This option is preferred when a user wants larger NURBS surfaces but not at the cost of additional NURBS control points.

Small = 3

NURBS surfaces will not be merged and will have clamped knots.

Unprocessed = 4

NURBS surfaces will not be merged and will have unclamped uniform knots. This is useful as a starting point for customized merging and modifying continuity at extraordinary vertices.
