gp_Sphere Class Reference

Describes a sphere.
A sphere is defined by its radius and positioned in space
with a coordinate system (a gp_Ax3 object). The origin of
the coordinate system is the center of the sphere. This
coordinate system is the "local coordinate system" of the sphere.
Note: when a gp_Sphere sphere is converted into a
Geom_SphericalSurface sphere, 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 sphere and the origin of the parameters,
- its implicit orientation (right-handed or left-handed)
gives the orientation (direct, indirect) to the
Geom_SphericalSurface sphere.
See Also
gce_MakeSphere which provides functions for more
complex sphere constructions
Geom_SphericalSurface which provides additional
functions for constructing spheres and works, in
particular, with the parametric equations of spheres.
