### `[constexpr noexcept]` QSurfaceDataItem::QSurfaceDataItem()

Constructs a surface data item.

### `[explicit constexpr noexcept]` QSurfaceDataItem::QSurfaceDataItem(QVector3D position)

Constructs a surface data item at the position position.

### `[constexpr noexcept]` QSurfaceDataItem::QSurfaceDataItem(float x, float y, float z)

Constructs a surface data item at the position specified by x, y, and z.

### `[constexpr noexcept]` QVector3D QSurfaceDataItem::position() const

Returns the position of this data item.

See also setPosition().
