AnyCAD.Foundation.GSphere类 参考

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 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. 更多...
