package GeomAPI
|
|
|
|
---Purpose: 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 <P> and a curve <C>, one can writes :
|
|
--
|
|
-- D = GeomAPI_ProjectPointOnCurve(P,C);
|
|
--
|
|
-- or
|
|
--
|
|
-- GeomAPI_ProjectPointOnCurve PonC(P,C);
|
|
-- D = PonC.LowerDistance();

To2d(C : Curve from Geom; P : Pln from gp) returns Curve from Geom2d;
|
|
---Purpose: 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(C : Curve from Geom2d; P : Pln from gp) returns Curve from Geom;
|
|
---Purpose: 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.
