NurbsSurface.CreateCurveOnSurfacePoints

Public Class

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.

Namespace: Rhino.Geometry

Assembly: RhinoCommon (in RhinoCommon.dll)

**Since:**6.3

Syntax

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

Parameters

surface

Type: Rhino.Geometry.Surface
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.Generic.IEnumerable. Point2d.
Surface points to interpolate given by parameters. These must be distinct.

tolerance

Type:System.Double
Relative tolerance used by the solver. When in doubt, use a tolerance of 0.0.

periodic

Type:System.Boolean
When true constructs a smoothly closed curve.

initCount

Type:System.Int32
Maximum number of points to insert between fixed points on the first level.

levels

Type:System.Int32
The number of levels (between 1 and 3) to be used in multi-level solver. Use 1 for single level solve.

Return Value

Type:. Point2d.
A sequence of surface points, given by surface parameters, if successful. The number of output points is approximately: 2 ^ (level-1) * initCount * fixedPoints.Count.

Remarks

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