Detailed Description#

The QJoint 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.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property inverseBindMatrixᅟ: QMatrix4x4#

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.

Access functions:

inverseBindMatrix()
setInverseBindMatrix()
Signal inverseBindMatrixChanged()

property nameᅟ: str#

Access functions:

name()
setName()
Signal nameChanged()

property rotationᅟ: QQuaternion#

Holds the rotation of the joint as QQuaternion.

Access functions:

rotation()
setRotation()
Signal rotationChanged()

property rotationXᅟ: float#

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

Access functions:

rotationX()
setRotationX()
Signal rotationXChanged()

property rotationYᅟ: float#

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

Access functions:

rotationY()
setRotationY()
Signal rotationYChanged()

property rotationZᅟ: float#

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

Access functions:

rotationZ()
setRotationZ()
Signal rotationZChanged()

property scaleᅟ: QVector3D#

Holds the scale of the joint.

Access functions:

scale()
setScale()
Signal scaleChanged()

property translationᅟ: QVector3D#

Holds the translation of the joint as QVector3D.

Access functions:

translation()
setTranslation()
Signal translationChanged()

__init__([parent=None])#

Parameters:: parent – QNode

Constructs a new QJoint with parent.

addChildJoint(joint)#

Parameters:: joint – QJoint

Adds joint as a child of this joint. If joint has no parent, then this joint takes ownership of it. Child joints are in the coordinate system of their parent joint.

childJoints()#

Return type:: .list of Qt3DCore.QJoint

The vector of joints this joint has as children.

inverseBindMatrix()#

Return type:: QMatrix4x4

inverseBindMatrixChanged(inverseBindMatrix)#

Parameters:: inverseBindMatrix – QMatrix4x4

Notification signal of property inverseBindMatrixᅟ .

name()#

Return type:: str

Returns the name of the joint.
