QConeGeometry Class

class Qt3DExtras::QConeGeometry

The QConeGeometry class allows creation of a cone in 3D space. * * * * * The QConeGeometry class is most commonly used internally by the QConeMesh * but can also be used in custom Qt3DRender::QGeometryRenderer subclasses. The class * allows for creation of both a cone and a truncated cone. More...
