Orientation in Extended Position-Based Dynamics: Application to Rigid Bodies and Cosserat Rods

XPBD is getting a serious orientation upgrade: a new Lie-theory framework makes rotational constraints, interpolation, and differentiation much cleaner. The payoff is a rigid-body simulation consistency boost of more than 10,000x over prior XPBD methods, plus better Cosserat rod behavior. For teams leaning on position-based solvers, that could mean sturdier constraints and smoother deformables.
