## NurbsSurfaceCreateCurveOnSurfacePoints Method |

Computes a discrete spline curve on the surface. In other words, computes a sequence
of points on the surface, each with a corresponding parameter value.

Syntax

public static Point2d[] CreateCurveOnSurfacePoints( Surface surface, IEnumerable<Point2d> fixedPoints, double tolerance, bool periodic, int initCount, int levels )

- surface
- Type: Rhino.GeometrySurface

The surface on which the curve is constructed. The surface should be G1 continuous. If the surface is closed in the u or v direction and is G1 at the seam, the function will construct point sequences that cross over the seam. - fixedPoints
- Type: System.Collections.GenericIEnumerablePoint2d

Surface points to interpolate given by parameters. These must be distinct. - tolerance
- Type: SystemDouble

Relative tolerance used by the solver. When in doubt, use a tolerance of 0.0. - periodic
- Type: SystemBoolean

When true constructs a smoothly closed curve. - initCount
- Type: SystemInt32

Maximum number of points to insert beteween fixed points on the first level. - levels
- Type: SystemInt32

The number of levels (between 1 and 3) to be used in multi-level solver. Use 1 for single level solve.

A sequence of surface points, given by surface parameters, if successful. The number of output points is approximatelely: 2 ^ (level-1) * initCount * fixedPoints.Count.

Remarks

To create a curve from the output points, use Surface.CreateCurveOnSurface.
