详细描述

Defines an infinite conical surface. A cone is defined by its half-angle (can be negative) 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
