示例1:
//constraint between two different rigidbodies
btVehicleJacobianEntry(
const Basis &world2A,
const Basis &world2B,
const Vector3 &rel_pos1,
const Vector3 &rel_pos2,
const Vector3 &jointAxis,
const Vector3 &inertiaInvA,
const real_t massInvA,
const Vector3 &inertiaInvB,
const real_t massInvB) :
m_linearJointAxis(jointAxis) {
m_aJ = world2A.xform(rel_pos1.cross(m_linearJointAxis));
m_bJ = world2B.xform(rel_pos2.cross(-m_linearJointAxis));
m_0MinvJt = inertiaInvA * m_aJ;
m_1MinvJt = inertiaInvB * m_bJ;
m_Adiag = massInvA + m_0MinvJt.dot(m_aJ) + massInvB + m_1MinvJt.dot(m_bJ);
//btAssert(m_Adiag > real_t(0.0));
