IGetTessPts Method (ICurve)

Gets a set of points that represent the tessellation of this curve.

.NET Syntax

Visual Basic (Declaration) 
Function IGetTessPts( _
   ByVal ChordTolerance As Double, _
   ByVal LengthTolerance As Double, _
   ByRef StartPoint As Double, _
   ByRef EndPoint As Double _
) As Double
Visual Basic (Usage) 
Dim instance As ICurve
Dim ChordTolerance As Double
Dim LengthTolerance As Double
Dim StartPoint As Double
Dim EndPoint As Double
Dim value As Double
value = instance.IGetTessPts(ChordTolerance, LengthTolerance, StartPoint, EndPoint)
double IGetTessPts( 
   double ChordTolerance,
   double LengthTolerance,
   ref double StartPoint,
   ref double EndPoint
double IGetTessPts( 
&   double ChordTolerance,
&   double LengthTolerance,
&   double% StartPoint,
&   double% EndPoint



Chord tolerance to use in tessellation (meters); this is the maximum permitted distance from a cord to the curve between the cord endpoints; the smallest allowable value for this parameter is 1E-8; if 0.0 or a value smaller than 1E-8 is specified, then 1E-8 is used by default


Length tolerance to be used to filter out very short segments (meters); this method does not return tessellated segments shorter than this value


Pointer to an array containing the start point of the curve


Pointer to an array containing the end point of the curve

Return Value

  • in-process, unmanaged C++: Pointer to an array containing the tessellation points (see Remarks)
  • VBA, VB.NET, C#, and C++/CLI: Not supported
  • See In-process Methods for details about this type of method.


    The array returned contains the x, y, z location of the tessellation points:

    [ x1, y1, z1, x2, y2, z2, ... ]

    Before calling this method, call ICurve::IGetTessPtsSize to determine the size of the array needed to contain the return values of this method.
