| gp_Sphere () |
| Creates an indefinite sphere.
|
| gp_Sphere (const gp_Ax3 &A3, const Standard_Real Radius) |
| Constructs a sphere with radius Radius, centered on the origin

|
void | SetPosition (const gp_Ax3 &A3) |
| Changes the local coordinate system of the sphere.
|
void | SetRadius (const Standard_Real R) |
| Assigns R the radius of the Sphere.
Warnings :
It is not forbidden to create a sphere with null radius.
Raises ConstructionError if R < 0.0
