	GProp_GProps ()
	The origin (0, 0, 0) of the absolute cartesian coordinate system is used to compute the global properties. More...
	GProp_GProps (const gp_Pnt &SystemLocation)
	The point SystemLocation is used to compute the gobal properties <br> of the system. For more accuracy it is better to define this point closed to the location of the system. For example it could be a point around the centre of mass of the system. This point is referred to as the reference point for this framework. For greater accuracy it is better for the reference point to be close to the location of the system. It can, for example, be a point near the center of mass of the system. At initialization, the framework is empty; i.e. it retains no dimensional information such as mass, or inertia. However, it is now able to bring together global properties of various other systems, whose global properties have already been computed using another framework. To do this, use the function Add to define the components of the system. Use it once per component of the system, and then use the interrogation functions available to access the computed values.

void	Add (const GProp_GProps &Item, const Standard_Real Density=1.0)
	Either More...
Standard_Real	Mass () const
	Returns the mass of the current system. <br> If no density is attached to the components of the current system the returned value corresponds to : More...
gp_Pnt	CentreOfMass () const
	Returns the center of mass of the current system. If <br> the gravitational field is uniform, it is the center of gravity. The coordinates returned for the center of mass are expressed in the absolute Cartesian coordinate system. More...
gp_Mat	MatrixOfInertia () const
	returns the matrix of inertia. It is a symmetrical matrix. <br> The coefficients of the matrix are the quadratic moments of inertia. | Ixx Ixy Ixz | matrix = | Ixy Iyy Iyz | | Ixz Iyz Izz | The moments of inertia are denoted by Ixx, Iyy, Izz. The products of inertia are denoted by Ixy, Ixz, Iyz. The matrix of inertia is returned in the central coordinate system (G, Gx, Gy, Gz) where G is the centre of mass of the system and Gx, Gy, Gz the directions parallel to the X(1,0,0) Y(0,1,0) Z(0,0,1) directions of the absolute cartesian coordinate system. It is possible to compute the matrix of inertia at another location point using the Huyghens theorem (you can use the method of package GProp : HOperator). More...
void	StaticMoments (Standard_Real &Ix, Standard_Real &Iy, Standard_Real &Iz) const
	Returns Ix, Iy, Iz, the static moments of inertia of the <br> current system; i.e. the moments of inertia about the three axes of the Cartesian coordinate system. More...
Standard_Real	MomentOfInertia (const gp_Ax1 &A) const
	computes the moment of inertia of the material system about the axis A. More...
GProp_PrincipalProps	PrincipalProperties () const
	Computes the principal properties of inertia of the current system. <br> There is always a set of axes for which the products of inertia of a geometric system are equal to 0; i.e. the matrix of inertia of the system is diagonal. These axes are the principal axes of inertia. Their origin is coincident with the center of mass of the system. The associated moments are called the principal moments of inertia. This function computes the eigen values and the eigen vectors of the matrix of inertia of the system. Results are stored by using a presentation framework of principal properties of inertia (GProp_PrincipalProps object) which may be queried to access the value sought. More...
Standard_Real	RadiusOfGyration (const gp_Ax1 &A) const
	Returns the radius of gyration of the current system about the axis A. More...
