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 :

The API provides classes to call the algorithms of the Geometry

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();

◆ To2d()

static Handle< Geom2d_Curve > GeomAPI::To2d ( const Handle< Geom_Curve > &  C,
const gp_Pln P 
)
static

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:

  • 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.

◆ To3d()

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 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.
