Specifies the parameter from which the length is to be measured.
Specifies the parameter to which the length is to be measured.
Returns the length between the specified parameters.
Description
Returns the length, measured along the curve, from one given parameter to another.
Syntax
Visual Basic
Public Sub GetLengthAtParam( _
ByVal FromParam As Double, _
ByVal ToParam As Double, _
ByRef Length As Double _
)
Parameters
FromParam
Specifies the parameter from which the length is to be measured.
ToParam
Specifies the parameter to which the length is to be measured.
Length
Returns the length between the specified parameters.
Remarks
If either of the input parameters is out of the bounds of the curve's parametric range, GetLengthAtParam snaps the value to the closest endpoint before computing the Length.
