gp_Cone Class Reference

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 <br> 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
