Detailed Description

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.
