Syntax
C++
bool getPoles(OdGeDoubleArray * uParams, OdGeDoubleArray * vParams, OdGePoint3dArray * uPoints, OdGePoint3dArray * vPoints, double tol = 1e-13) const;
Parameters
Parameters 
Description 
OdGeDoubleArray * uParams 
[out] (Optional) Pointer to an array that receives U-params for poles with U = const.  
OdGeDoubleArray * vParams 
[out] (Optional) Pointer to an array that receives V-params for poles with V = const.  
OdGePoint3dArray * uPoints 
[out] (Optional) Pointer to an array that receives 3D points for poles with U = const.  
OdGePoint3dArray * vPoints 
[out] (Optional) Pointer to an array that receives 3D points for poles with V = const.  
double tol = 1e-13 
[in] Geometric tolerance. 
Returns

true if the surface has poles, false otherwise.

Description

Finds all poles of surface. Surface envelope not considered. In case of NurbSurface extreme points of envelope are checked. Input arrays may be not empty. In this case new poles will be written to the ends of the arrays.
