Verifies that a point is on a curve.
rhinoscriptsyntax.IsPointOnCurve (object_id, point, segment_index=-1)
rhinoscript.curve.IsPointOnCurve (object_id, point, segment_index=-1)
object_id |
Required. String or Guid. The object's identifier. |
point |
Required. List of 3 numbers or Point3d. The test, or sampling, point. |
segment_index |
Optional. Number. If object_id identifies a polycurve object, then segment_index identifies the curve segment of the polycurve to query. |
Boolean |
True if successful, otherwise False. |
