 GProp_GProps (const gp_Pnt &SystemLocation)
 The point SystemLocation is used to compute the global properties 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.

gp_Mat MatrixOfInertia () const
 returns the matrix of inertia. It is a symmetrical matrix. The coefficients of the matrix are the quadratic moments of inertia. More...
 
void StaticMoments (Standard_Real &Ix, Standard_Real &Iy, Standard_Real &Iz) 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. 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

Detailed Description

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

The surface can be :

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.
