OdGeCurve2d::closestPointTo Method (OdGePoint2d&, double&, OdGeInterval*, OdGeTol&)
Collapse All
Syntax
C++
OdGePoint2d closestPointTo(const OdGePoint2d& point, double& param, const OdGeInterval* range, const OdGeTol& tol = OdGeContext::gTol) const;
Parameters
Parameters 
Description 
const OdGePoint2d& point 
[in] Point to be evaluated.  
double& param 
[out] uv-coord of closest point.  
const OdGeInterval* range 
[in] Interval on the curve.  
const OdGeTol& tol = OdGeContext::gTol 
[in] Geometric tolerance.  
Returns

The closest point on this curve.

Description

Finds the closest point on this curve to the input point. 

 

Remarks

Native interval is not considered. If projection of the point does not lie in range-interval, the closest bound of the interval is returned. In case of uvBox == NULL closestPointTo(point, range, tol) is called where range is a native curves interval. An unbounded interval should not be used here.
