- inverseBindMatrix : matrix4x4
- rotation : quaternion
- rotationX : real
- rotationY : real
- rotationZ : real
- scale : vector3d
- translation : vector3d

## Detailed Description

The Joint node is used to build skeletons as part of the skinned mesh support in Qt 3D. A joint can be transformed by way of its scale, rotation and translation properties. Any mesh vertices that are bound to the joint will have their transformations updated accordingly.

## Property Documentation

[read-only] childJoints : list<Joint>

inverseBindMatrix : matrix4x4

Holds the inverse bind matrix of the joint. This is used to transform vertices from model space into the space of this joint so they can subsequently be multiplied by the joint's global transform to perform the skinning operation.

rotation : quaternion

Holds the rotation of the joint as quaternion.

rotationX : real

Holds the x rotation of the joint as an Euler angle.

rotationY : real

Holds the y rotation of the joint as an Euler angle.

rotationZ : real

Holds the z rotation of the joint as an Euler angle.

scale : vector3d

Holds the uniform scale of the joint.

translation : vector3d

Holds the translation of the joint as vector3d.
