i want to contribute a bit

to btScalar.h:

Code: Select all

SIMD_FORCE_INLINE btScalar btRecip( const btScalar& x ) { return x != btScalar(0.0) ? btScalar(1.0) / x: btScalar(0.0); }

to btVector3.h, method of btVector3 class:

Code: Select all

SIMD_FORCE_INLINE	btVector3	getRecip() const
{
	return btVector3( btRecip(m_floats[0]), btRecip(m_floats[1]), btRecip(m_floats[2]) );
}

to btRigidBody.cpp:

Code: Select all

void btRigidBody::setMassProps(btScalar mass, const btVector3& inertia)
{
	m_inverseMass = btRecip(mass);
	if (mass == btScalar(0.))
		m_collisionFlags |= btCollisionObject::CF_STATIC_OBJECT;
	else
		m_collisionFlags &= (~btCollisionObject::CF_STATIC_OBJECT);

	//Fg = m * a
	m_gravity = mass * m_gravity_acceleration;
	
	m_invInertiaLocal = inertia.getRecip();
	m_invMass = m_linearFactor*m_inverseMass;
}

less code, faster compilation. I have Pentium I.
