| void | pinocchio::computeJointKinematicHessians (const ModelTpl< Scalar, Options, JointCollectionTpl > &model, DataTpl< Scalar, Options, JointCollectionTpl > &data) |
| Computes all the terms required to compute the second order derivatives of the placement information, also know as the kinematic Hessian. This function assumes that the joint Jacobians (a.k.a data.J) has been computed first. See computeJointJacobians for such a function. More... | |

| Computes the partial derivaties of the spatial acceleration of a given with respect to the joint configuration, velocity and acceleration. You must first call computForwardKinematicsDerivatives before calling this function. It is important to notice that a direct outcome (for free) of this algo is v_partial_dq and v_partial_dv which is equal to a_partial_da. More... | |

Retrieves the kinematic Hessian of a given joint according to the values aleardy computed by computeJointKinematicHessians and stored in data. While the kinematic Jacobian of a given joint frame corresponds to the first order derivative of the placement variation with respect to  , the kinematic Hessian corresponds to the second order derivation of placement variation, which in turns also corresponds to the first order derivative of the kinematic Jacobian. The frame in which the kinematic Hessian is precised by the input argument rf. More... | |
