 BRepGProp_MeshCinert ()
 
void SetLocation (const gp_Pnt &CLocation)
 
void Perform (const NCollection_Array1< gp_Pnt > &theNodes)
 Computes the global properties of of polylines represented by set of points.
 
- Public Member Functions inherited from GProp_GProps
 GProp_GProps ()
 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.
 
void Add (const GProp_GProps &Item, const double Density=1.0)
 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
 Returns the static moments of inertia of the current system - i.e. the moments of inertia about the three axes of the absolute Cartesian coordinate system.
 
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.
 
double RadiusOfGyration (const gp_Ax1 &A) const
 Returns the radius of gyration of the current system about the axis A.
