calculateMassInfo method

@override void calculateMassInfo(MassInfo out)

Calculate the mass information of the shape.

Implementation

@override
	void calculateMassInfo( out ) {
		double mass = volume() * radius * radius * density;
		out.mass = mass;
		double inertia = mass * radius * radius * 0.4;
		out.inertia.set( inertia, 0, 0, 0, inertia, 0, 0, 0, inertia );
	}
