BRepGProp_Cinert Class Reference

Computes the global properties of bounded curves in 3D space. The curve must have at least a continuity C1. It can be a curve as defined in the template CurveTool from package GProp. This template gives the minimum of methods required to evaluate the global properties of a curve 3D with the algorithms of GProp. More...

	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.

Detailed Description

Computes the global properties of bounded curves in 3D space. The curve must have at least a continuity C1. It can be a curve as defined in the template CurveTool from package GProp. This template gives the minimum of methods required to evaluate the global properties of a curve 3D with the algorithms of GProp.
