	The origin (0, 0, 0) of the absolute Cartesian coordinate system is used to compute the global properties.

	GProp_GProps (const gp_Pnt &SystemLocation)
	The point SystemLocation is used to compute the global properties of the system. For greater accuracy, define this point close to the location of the system; for example a point near the centre of mass of the system.

	Either:

double	Mass () const
	Returns the mass of the current system.

gp_Pnt	CentreOfMass () const
	Returns the centre of mass of the current system. With a uniform gravitational field this is also the centre of gravity. The coordinates returned for the centre of mass are expressed in the absolute Cartesian coordinate system.

gp_Mat	MatrixOfInertia () const
	Returns the matrix of inertia. It is a symmetric matrix whose coefficients are the quadratic moments of inertia:

void	StaticMoments (double &Ix, double &Iy, double &Iz) const

double	MomentOfInertia (const gp_Ax1 &A) const
	Computes the moment of inertia of the system about the axis A.

GProp_PrincipalProps	PrincipalProperties () const
	Computes the principal properties of inertia of the current system. 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 coincides with the centre of mass of the system. The associated moments are called the principal moments of inertia.

Detailed Description

Computes the global properties of a geometric solid (3D closed region of space) delimited with :

a point and a surface
a plane and a surface

The surface can be :

a surface limited with its parametric values U-V, (naturally restricted)
a surface limited in U-V space with its boundary curves.

The surface's requirements to evaluate the global properties are defined in the template FaceTool class from the package GProp.

The adaptive 2D algorithm of Gauss-Kronrod integration of double integral is used.

The inner integral is computed along U parameter of surface. The integrand function is encapsulated in the support class UFunction that is defined below.

The outer integral is computed along T parameter of a bounding curve. The integrand function is encapsulated in the support class TFunction that is defined below.
