OdGeCurve3d::paramOf Method (OdGePoint3d&, OdGeInterval*, OdGeTol&)
|
Parameters |
Description |
|
const OdGePoint3d& point |
[in] Point to be evaluated. |
|
const OdGeInterval* range |
[in] Interval on the curve. |
|
const OdGeTol& tol = OdGeContext::gTol |
[in] Geometric tolerance. |
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, end or start of the interval will be set. In case of uvBox == NULL paramOf(point, rng, tol) is called in which range - native range of the curve. If you are not sure whether the point is on this curve, use isOn() instead of this function.
