Mass ()

Creates an uninitialized mass.

Mass (EDirectInit init_mode, dReal value, const osg::Vec3 &size)

Creates and initializes the mass for BOX and BOX_TOTAL.

Mass (EDirectInit init_mode, dReal value, dReal radius)

Creates and initializes the mass for SPHERE and SPHERE_TOTAL.

Mass (EDirectInit init_mode, dReal value, EAxis axis, dReal radius, dReal length)

Creates and initializes the mass for CYLINDER/CAPSULE and CYLINDER_TOTAL/CAPSULE_TOTAL.

Mass & operator= (const Mass &v)

dReal getMass () const

osg::Matrix getInertiaTensor () const

osg::Vec3 getCenter ()

Gets the center of mass.

osg::Vec3 centerMass ()

Sets the center of mass to be (0,0,0) and returns the translation that has occured.

void adjust (dReal mass)

Sets mass and adjusts the inertia matrix (to keep data consistent).

void addMass (const Mass &m2)

Add some mass to the current mass (when adding or removing somme matter).

Mass & operator+= (const Mass &m2)

void translateMass (const osg::Vec3 &vec)

void rotateMass (const osg::Quat &q)

void rotateMass (const osg::Matrix &m)

void setSphere (dReal density, dReal radius)

Computes everything that is needed for the mass to behave as a sphere.

Detailed Description

Wrapper for mass parameters.

The underlaying dMass structure is hidden to allow mass modification without having to re-set body masses afterwards.
