GProp Class Reference

This package defines algorithmes to compute the global properties
of a set of points, a curve, a surface, a solid (non infinite
region of space delimited with geometric entities), a compound
geometric system (heterogeneous composition of the previous
entities).

Global properties are :
. length, area, volume,
. centre of mass,
. axis of inertia,
. moments of inertia,
. radius of gyration.

It provides also a class to compile the average point or
line of a set of points.

static void GProp::HOperator	(	const gp_Pnt &	G,
		const gp_Pnt &	Q,
		const Standard_Real	Mass,
		gp_Mat &	Operator
	)		[static]

• Mass, i.e. the mass of the system,
  
• G, the center of mass of the system.
  The "Huyghens Operator" is used to compute
  Inertia/Q, the matrix of inertia of the system at
  the point Q using Huyghens' theorem :
  Inertia/Q = Inertia/G + HOperator (Q, G, Mass)
  where Inertia/G is the matrix of inertia of the
  system relative to its center of mass as returned by
  the function MatrixOfInertia on any GProp_GProps object.
