| Geom2dLProp_CLProps2d (const Handle< Geom2d_Curve > &C, const Standard_Integer N, const Standard_Real Resolution) | |
Initializes the local properties of the curve The current point and the derivatives are computed at the same time, which allows an optimization of the computation time. <N> indicates the maximum number of derivations to be done (0, 1, 2 or 3). For example, to compute only the tangent, N should be equal to 1. <Resolution> is the linear tolerance (it is used to test if a vector is null). More... | |
| Geom2dLProp_CLProps2d (const Handle< Geom2d_Curve > &C, const Standard_Real U, const Standard_Integer N, const Standard_Real Resolution) | |
Same as previous constructor but here the parameter is set to the value <U>. All the computations done will be related to and <U>. More... | |
| Geom2dLProp_CLProps2d (const Standard_Integer N, const Standard_Real Resolution) | |
Same as previous constructor but here the parameter is set to the value <U> and the curve is set with SetCurve. the curve can have a empty constructor All the computations done will be related to and <U> when the functions "set" will be done. More... | |
