Class: CurvatureBasedInterpolator

PathBuilding.Pipeline.CurvatureBasedInterpolator(calculateDerivatesopt, keepSplineParametersopt)

Catmull-Rom spline interpolator.Provided with Catmull-Rom spline control points, produces multiple sample points of the same kind along the spline trajectory.

Constructor

new CurvatureBasedInterpolator(calculateDerivatesopt, keepSplineParametersopt)

Parameters:

Name	Type	Attributes	Default	Description
calculateDerivates	boolean	<optional>	false	The derivatives of the curve are calculated for each sample point. This is needed for some modes of the raster rendering.
keepSplineParameters	boolean	<optional>	false	Interpolated spline contains SplineParameter for every sampled point.

Properties:

Name	Type	Attributes	Default	Description
errorThreshold	float	<optional>	0.15	Gets or sets the allowed difference between the actual and the interpolated curve
maxRecursionDepth	int	<optional>	100	Subdivide max resurions allowed
