(
QVector3D
position
)
Constructs scatter data item with position position .
[explicit noexcept]
QScatterDataItem::
QScatterDataItem
(
QVector3D

QVector3D
QScatterDataItem::
位置
() const
Returns the position of this data item.
另请参阅 setPosition ().
Returns the rotation of this data item.
另请参阅 setRotation ().
[noexcept]
void
QScatterDataItem::
setPosition
(
QVector3D
pos
)
Sets the position pos for this data item.
另请参阅 位置 ().
[noexcept]
void
QScatterDataItem::
setRotation
(const
QQuaternion
