The GeomAPI package provides an Application
Programming Interface for the Geometry.
The API is a set of classes and methods aiming to
provide :
* High level and simple calls for the most common
operations.
* Keeping an access on the low-level
implementation of high-level calls.
The API provides classes to call the algorithmes
of the Geometry
* The constructors of the classes provides the
different constructions methods.
* The class keeps as fields the different tools
used by the algorithmes
* The class provides a casting method to get
automatically the result with a function-like
call.
For example to evaluate the distance <D> between a
point.

static Handle_Geom2d_Curve | To2d (const Handle< Geom_Curve > &C, const gp_Pln &P) |
To intersect a curve and a surface. //! This function builds (in the parametric space of the plane P) a 2D curve equivalent to the 3D curve C. The 3D curve C is considered to be located in the plane P. Warning The 3D curve C must be of one of the following types: | |
static Handle_Geom_Curve | To3d (const Handle< Geom2d_Curve > &C, const gp_Pln &P) |
Builds a 3D curve equivalent to the 2D curve C described in the parametric space defined by the local coordinate system of plane P. The resulting 3D curve is of the same nature as that of the curve C. |
and a curve , one can writes :
D = GeomAPI_ProjectPointOnCurve(P,C);
or
GeomAPI_ProjectPointOnCurve PonC(P,C);
D = PonC.LowerDistance();
