 * Interpolates a simulated 4D rigid-body pose onto an ObjectN scene node.

 * The binding stores two simulation snapshots. Call `capture()` after every
 * fixed physics step, then call `apply(alpha)` before the scene's single
 * `updateWorld()` traversal. `alpha=0` selects the previous snapshot and
 * `alpha=1` the current one.
 *
 * Body poses are world-space. If the target node is parented, `apply()`
 * converts the interpolated pose through the parent's current world transform
 * so hierarchy composition reconstructs the body pose exactly.
