Detailed Description

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.

Constructor & Destructor Documentation

GSphere.GSphere

(

)

Creates an indefinite sphere.

GSphere.GSphere	(	GAx3	A3,
		double	Radius
	)

Constructs a sphere with radius Radius, centered on the origin of A3. A3 is the local coordinate system of the sphere. Warnings : It is not forbidden to create a sphere with null radius. Raises ConstructionError if Radius < 0.0

Member Function Documentation

double GSphere.Area

(

)

Computes the aera of the sphere.

void GSphere.Coefficients	(	double[]	A1,
		double[]	A2,
		double[]	A3,

		double[]	B2,
		double[]	B3,
		double[]	C1,
		double[]	C2,
		double[]	C3,
		double[]	D
	)

Computes the coefficients of the implicit equation of the quadric in the absolute cartesian coordinates system : A1.X**2 + A2.Y**2 + A3.Z**2 + 2.(B1.X.Y + B2.X.Z + B3.Y.Z) + 2.(C1.X + C2.Y + C3.Z) + D = 0.0

boolean GSphere.Direct

(

)

Returns true if the local coordinate system of this sphere is right-handed.

GPnt GSphere.Location

(

)

— Purpose ; Returns the center of the sphere.

GSphere GSphere.Mirrored

(

GPnt

P

)

Performs the symmetrical transformation of a sphere with respect to the point P which is the center of the symmetry.

GSphere GSphere.Mirrored

(

GAx1

A1

)

Performs the symmetrical transformation of a sphere with respect to an axis placement which is the axis of the symmetry.

GSphere GSphere.Mirrored

(

GAx2

A2

)

Performs the symmetrical transformation of a sphere with respect to a plane. The axis placement A2 locates the plane of the of the symmetry : (Location, XDirection, YDirection).

GAx3 GSphere.Position

(

)

Returns the local coordinates system of the sphere.

double GSphere.Radius

(

)

Returns the radius of the sphere.

GSphere GSphere.Rotated	(	GAx1	A1,
