OdGeCurve3d::paramOf Method (OdGePoint3d&, OdGeTol&)
|
Parameters |
Description |
|
const OdGePoint3d& point |
[in] Point to be evaluated. |
|
const OdGeTol& tol = OdGeContext::gTol |
[in] Geometric tolerance. |
Parameter value of the point.
Returns the parameter value of a point.
The returned parameter specifies a point within the tolerance of the point. If the point is not on this curve, the results are unpredictable. If you are not sure whether the point is on this curve, use isOn() instead of this function.
If projection of the point does not lie in range-interval, the closest bound of the interval is returned. In case of uvBox == NULL paramOf(point, tol) is called.
