| accelerations | Supplied list of floats to read back and store the joint accelerations data. |
int Total degrees of freedom for the entire hierarchy of articulation bodies.
Reads back articulation body joint accelerations of the entire hierarchy to the supplied list of floats .
This returns joint accelerations in the reduced coordinate space for the entire articulation hierarchy starting from root to the supplied list of floats.
Every joint acceleration DOF is represented by one float value, however depending on the type of the articulation joint there might be zero, one or 3 DOFs per joint.
The exact location of the data in resulting list for the specific articulation body can be found by calling ArticulationBody.GetDofStartIndices and indexing returned dofStartIndices list by the particular body index via ArticulationBody.index.
Number of degrees of freedom for the articulation body can be found using ArticulationBody.dofCount.
Units of measurement - m/s^2 (meters per second squared) for linear and rad/s^2 (radians per second squared) for angular motion.
