Detailed Description
Encapsulates geometry
A Qt3DRender::QGeometry class is used to group a list of Qt3DRender::QAttribute objects together to form a geometric shape Qt3D is able to render using Qt3DRender::QGeometryRenderer. Special attribute can be set in order to calculate bounding volume of the shape.
Property Documentation
boundingVolumePositionAttribute : Qt3DRender::QAttribute*
Holds the attribute used to compute the bounding volume. The bounding volume is used internally for picking and view frustum culling.
If unspecified, the system will look for the attribute using the name returned by QAttribute::defaultPositionAttributeName.
Access functions:
Qt3DRender::QAttribute * | boundingVolumePositionAttribute() const |
void | setBoundingVolumePositionAttribute(Qt3DRender::QAttribute *boundingVolumePositionAttribute) |
Notifier signal:
void | boundingVolumePositionAttributeChanged(Qt3DRender::QAttribute *boundingVolumePositionAttribute) |

Member Function Documentation
QGeometry::QGeometry(Qt3DCore::QNode *parent = nullptr)
Constructs a new QGeometry with parent.
void QGeometry::addAttribute(Qt3DRender::QAttribute *attribute)
Adds an attribute to this geometry.
Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.
QVector<Qt3DRender::QAttribute *> QGeometry::attributes() const
Returns the list of attributes in this geometry.
void QGeometry::removeAttribute(Qt3DRender::QAttribute *attribute)
Removes the given attribute from this geometry.
Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.
