Description:
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.
Parameters:
- surface
- Type: 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: IEnumerable<Point2d>
- Surface points to interpolate given by parameters. These must be distinct.
- tolerance
- Type: double
- Relative tolerance used by the solver. When in doubt, use a tolerance of 0.0.
- periodic
- Type: bool
- When True constructs a smoothly closed curve.
- initCount
- Type: int
- Maximum number of points to insert between fixed points on the first level.
- levels
- Type: int
- The number of levels (between 1 and 3) to be used in multi-level solver. Use 1 for single level solve.
Returns:
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.
