## Detailed Description

A Qt3DAnimation::QMorphTarget class is a convenience class, which provides a list of QAttributes, which the QMorphingAnimation uses to animate geometry. A QMorphTarget can also be created based on existing Qt3DCore::QGeometry.

## Property Documentation

### `[read-only]` attributeNames : const QStringList

Holds a list of attribute names contained in the morph target.

Access functions:

QStringList | attributeNames() const

Notifier signal:

void | attributeNamesChanged(const QStringList &attributeNames)

## Member Function Documentation

### `[explicit]` QMorphTarget::QMorphTarget(QObject *parent = nullptr)

Constructs a QMorphTarget with given parent.

### void QMorphTarget::addAttribute(Qt3DCore::QAttribute *attribute)

Adds an attribute the morph target. An attribute with the same name must not have been added previously to the morph target.

### QList<Qt3DCore::QAttribute *> QMorphTarget::attributeList() const

Returns a list of attributes contained in the morph target.

### `[static invokable]` Qt3DAnimation::QMorphTarget *QMorphTarget::fromGeometry(Qt3DCore::QGeometry *geometry, const QStringList &attributes)

Returns a morph target based on the attributes in the given geometry.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

### void QMorphTarget::removeAttribute(Qt3DCore::QAttribute *attribute)

Removes an attribute from the morph target.

### void QMorphTarget::setAttributes(const QList<Qt3DCore::QAttribute *> &attributes)

Sets attributes to the morph target. Old attributes are cleared.
