QCylinderGeometry Class

(Qt3DExtras::QCylinderGeometry)

The QCylinderGeometry class allows creation of a cylinder in 3D space. * * * * * The QCylinderGeometry class is most commonly used internally by the QCylinderMesh * but can also be used in custom Qt3DRender::QGeometryRenderer subclasses. More...
