- vr_arms.c: vr_finger_nodes, vr_pose_finger (after HaloCE-Quest-VR, CC0,
nearly verbatim): each finger's three joints found by name under the
hand, posed by absolute directions in the palm's frame (a little bent
at rest, a fist at full curl; the thumb up the handle or across the
palm), each segment's subtree turned with its length kept. Its touch
of the world (rays per finger) is left out for the Frame's processor.
- The free left hand takes its controller's curls (halo_vr_finger_curls:
index from the trigger, the others from the grip, the thumb from where
it rests; round a held grenade). On the foregrip the hand keeps the
weapon's pose.
- The hand on the weapon keeps its grip; only its index finger is lifted
part way off the trigger while the controller says it is (touch known
and the finger off it), never where touch is unknown.
- Joints found once per skeleton; the cost is a few dozen node turns.
