HandJointUtils Class

Utility methods for working with HandJointIds.

Public Statics

A list of joint arrays representing HandJointIds for each finger.
The list is indexed by the integer value of HandFinger.
An array indexed by the integer value of HandJointId which provides the corresponding HandFinger, if applicable.
If the joint used to index into this array is not a finger joint, the value at that index will be HandFinger.Invalid
An array indexed by the integer value of HandJointId which provides the parent HandJointId, if applicable.
If the joint used to index into this array does not have a valid parent, the value at that index will be HandFinger.Invalid
An array indexed by the integer value of HandJointId which provides an array of child HandJointIds, if applicable.
If the joint used to index into this array does not have children, the value at that index will be a zero-length array.

Static Member Functions

Returns the Tip joint corresponding to the provided HandFinger.
Parameters
finger
The finger to retrieve the tip for.
Returns
The fingertip joint.
Returns true for HandJointIds that represent finger tips.
Returns the "proximal" JointId for the given finger.
This is commonly known as the Knuckle. For fingers, proximal is the join with index 1; eg HandIndex1. For thumb, proximal is the joint with index 2; eg HandThumb2.
Translates an array of joint poses in wrist space to an orientation-only Quaternion array in local space.
Parameters
jointPoses
Joint poses in wrist space.
joints
Joint orientations in local space (local to the joint's parent).
Returns
True if the arrays provided are valid for this operation.
