GetNumberOfKnots

Description

Gets the number of distinct knots on a curve. The multiplicity of a knot is not taken into account.

Note: This command uses output arguments. C# and some scripting languages (such as JScript, PerlScript and Python) don't support arguments passed by reference so you need to use the best workaround for your situation:

For scripting languages this command returns an ISIVTCollection which you can use to get the output arguments.

For C# you can use the XSIApplication.ExecuteCommand method to call this command. ExecuteCommand packs the output arguments into a C# System.Object containing an Array of the output arguments (see Calling Commands from C#).

Scripting Syntax

    GetNumberOfKnots( InputObj, [NbItems] )

Parameters

Parameter | Type | Description
InputObj | String | Curve to evaluate.
NbItems [out] | Integer | Returns the number of knots.

Examples

VBScript Example

    'This example shows how to get the number of distinct knots from a curve
    newscene
    dim nbKnots
    'Create a standard spiral with 16 subdivisions.
    CreatePrim "Spiral", "NurbsCurve"
       ' Get the number of knots.
    GetNumberOfKnots "Spiral", nbKnots
    logmessage "Number of Knots: " & nbKnots
