OdGeNurbSurface::paramOfPrec Method
Collapse All
Syntax
C++
OdGePoint2d paramOfPrec(const OdGePoint3d& point, const OdGeTol& tol = OdGeContext::gTol) const;
Parameters
Parameters 
Description 
const OdGePoint3d& point 
[in] Point to be evaluated.  
const OdGeTol& tol = OdGeContext::gTol 
[in] Geometric tolerance. 
Returns

2D pair of parameter values of a point on this surface as a OdGePoint2d object.

Description

Returns the 2D pair of parameter values of a point on this surface. 

 

Remarks

The returned parameters specify a point within tol of point. If point is not on this surface, the results are unpredictable. If you are not sure the point is on this surface, use isOn() instead of this function. This method is slower than paramOf, but more accurate.
