Parameters

mainSegmentCount

Type: SystemInt32
If mainSegmentCount <= 0, then both subSegmentCount and mainSegmentCount are ignored. If mainSegmentCount > 0, then subSegmentCount must be >= 1. In this case the NURBS will be broken into mainSegmentCount equally spaced chords. If needed, each of these chords can be split into as many subSegmentCount sub-parts if the subdivision is necessary for the mesh to meet the other meshing constraints. In particular, if subSegmentCount = 0, then the curve is broken into mainSegmentCount pieces and no further testing is performed.

subSegmentCount

Type: SystemInt32
An amount of subsegments.

maxAngleRadians

Type: SystemDouble
( 0 to pi ) Maximum angle (in radians) between unit tangents at adjacent vertices.

maxChordLengthRatio

Type: SystemDouble
Maximum permitted value of (distance chord midpoint to curve) / (length of chord).

maxAspectRatio

Type: SystemDouble
If maxAspectRatio < 1.0, the parameter is ignored. If 1 <= maxAspectRatio < sqrt(2), it is treated as if maxAspectRatio = sqrt(2). This parameter controls the maximum permitted value of (length of longest chord) / (length of shortest chord).

tolerance

Type: SystemDouble
If tolerance = 0, the parameter is ignored. This parameter controls the maximum permitted value of the distance from the curve to the polyline.

minEdgeLength

Type: SystemDouble
The minimum permitted edge length.

maxEdgeLength

Type: SystemDouble
If maxEdgeLength = 0, the parameter is ignored. This parameter controls the maximum permitted edge length.

keepStartPoint

Type: SystemBoolean
If true the starting point of the curve is added to the polyline. If false the starting point of the curve is not added to the polyline.

curveDomain

Type: Rhino.GeometryInterval
This sub-domain of the NURBS curve is approximated.
