class Cone from gp inherits Storable
--- Purpose :
-- Defines an infinite conical surface.
-- A cone is defined by its half-angle at the apex and
-- positioned in space with a coordinate system (a gp_Ax3
-- object) and a "reference radius" where:
-- - the "main Axis" of the coordinate system is the axis of revolution of the cone,
-- - the plane defined by the origin, the "X Direction" and
-- the "Y Direction" of the coordinate system is the
-- reference plane of the cone; the intersection of the
-- cone with this reference plane is a circle of radius
-- equal to the reference radius,
-- if the half-angle is positive, the apex of the cone is on
-- the negative side of the "main Axis" of the coordinate
-- system. If the half-angle is negative, the apex is on the positive side.
-- This coordinate system is the "local coordinate system" of the cone.
-- Note: when a gp_Cone cone is converted into a
-- Geom_ConicalSurface cone, some implicit properties of
-- its local coordinate system are used explicitly:
-- - its origin, "X Direction", "Y Direction" and "main
-- Direction" are used directly to define the parametric
-- directions on the cone and the origin of the parameters,
-- - its implicit orientation (right-handed or left-handed)
-- gives the orientation (direct or indirect) of the
-- Geom_ConicalSurface cone.
-- See Also
-- gce_MakeCone which provides functions for more
-- complex cone constructions
-- Geom_ConicalSurface which provides additional
-- functions for constructing cones and works, in particular,
-- with the parametric equations of cones gp_Ax3
