详细描述

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 Qt3DRender::QGeometry .

QMorphTarget:: QMorphTarget ( QObject * parent = nullptr)

Constructs a QMorphTarget with given parent .

void QMorphTarget:: addAttribute ( Qt3DRender::QAttribute * attribute )

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

QVector < Qt3DRender::QAttribute *> QMorphTarget:: attributeList () const

Returns a list of attributes contained in the morph target.

[static] Qt3DAnimation::QMorphTarget *QMorphTarget:: fromGeometry ( Qt3DRender::QGeometry * geometry , const QStringList & attributes )

Returns a morph target based on the attributes 以给定 geometry .

注意: 此函数可以被援引,通过元对象系统和从 QML。见 Q_INVOKABLE .

void QMorphTarget:: removeAttribute ( Qt3DRender::QAttribute * attribute )

Removes an attribute from the morph target.

void QMorphTarget:: setAttributes (const QVector < Qt3DRender::QAttribute *> & attributes )

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