Detailed Description

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 <br>
     operations. <br>

• 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

and a curve , one can writes :

D = GeomAPI_ProjectPointOnCurve(P,C);

or

GeomAPI_ProjectPointOnCurve PonC(P,C);
D = PonC.LowerDistance();



Member Function Documentation

static Handle_Geom2d_Curve GeomAPI::To2d ( const Handle< Geom_Curve > &  C, const gp_Pln &  P  )

static

 To intersect a curve and a surface. <br>//! This function builds (in the <br>

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:

• a line
  
• a circle
  
• an ellipse
  
• a hyperbola
  
• a parabola
  
• a Bezier curve
  
• a BSpline curve
  Exceptions Standard_NoSuchObject if C is not a defined type curve.
  

static Handle_Geom_Curve GeomAPI::To3d ( const Handle< Geom2d_Curve > &  C, const gp_Pln &  P  )

static

 Builds a 3D curve equivalent to the 2D curve C <br>

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.
