TryGetBoneTransforms()

virtual HandPartTrackingState plXRHandTrackingInterface::TryGetBoneTransforms ( plEnum< plXRHand > hand, plEnum< plXRHandPart > handPart, plEnum< plXRTransformSpace > space, plDynamicArray< plXRHandBone > & out_bones )

pure virtual

Returns a array of bones in the given part of the hand.

Bones are always ordered from furthest from the body moving inwards. E.g. for a finger index 0 should be the tip followed by distal, etc. ending in the wrist bone. Depending on the implementation the number of bones returned can be less than the number of actual bones in the hand.

Implemented in plOpenXRHandTracking.
