---Copyright: Matra Datavision 1991 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 uses Ax1 from gp, Ax2 from gp, Ax3 from gp, Dir from gp, Pnt from gp, Trsf from gp, Vec from gp raises ConstructionError from Standard is Create returns Cone; ---C++:inline --- Purpose : Creates an indefinite Cone.
