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.
Property Documentation▲
inverseBindMatrix : 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:
-
QMatrix4x4 inverseBindMatrix() const
-
void setInverseBindMatrix(const QMatrix4x4 &inverseBindMatrix)
Notifier signal:
-
void inverseBindMatrixChanged(const QMatrix4x4 &inverseBindMatrix)
rotation : QQuaternion▲
Holds the rotation of the joint as QQuaternion.
Access functions:
-
QQuaternion rotation() const
-
void setRotation(const QQuaternion &rotation)
Notifier signal:
-
void rotationChanged(const QQuaternion &rotation)
rotationX : float▲
Holds the x rotation of the joint as an Euler angle.
Access functions:
-
float rotationX() const
-
void setRotationX(float rotationX)
Notifier signal:
-
void rotationXChanged(float rotationX)
rotationY : float▲
Holds the y rotation of the joint as an Euler angle.
Access functions:
-
float rotationY() const
-
void setRotationY(float rotationY)
Notifier signal:
-
void rotationYChanged(float rotationY)
rotationZ : float▲
Holds the z rotation of the joint as an Euler angle.
Access functions:
-
float rotationZ() const
-
void setRotationZ(float rotationZ)
Notifier signal:
-
void rotationZChanged(float rotationZ)
scale : QVector3D▲
Holds the scale of the joint.
Access functions:
-
QVector3D scale() const
-
void setScale(const QVector3D &scale)
Notifier signal:
-
void scaleChanged(const QVector3D &scale)
translation : QVector3D▲
Holds the translation of the joint as QVector3D.
Access functions:
-
QVector3D translation() const
-
void setTranslation(const QVector3D &translation)
Notifier signal:
-
void translationChanged(const QVector3D &translation)
Member Function Documentation▲
[explicit] QJoint::QJoint(Qt3DCore::QNode *parent = nullptr)▲
Constructs a new QJoint with parent.
void QJoint::addChildJoint(Qt3DCore::QJoint *joint)▲
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.
QList<Qt3DCore::QJoint *> QJoint::childJoints() const▲
The vector of joints this joint has as children.
QString QJoint::name() const▲
void QJoint::removeChildJoint(Qt3DCore::QJoint *joint)▲
Removes joint from this joint's list of children. The child joint is not destroyed.
void QJoint::setToIdentity()▲
Sets the transform matrix for this joint to the identity matrix.
